|4952 - How global warming works||25/06/2005 - 12:40:52|
|by Ed Grabianowski|
Well, is it? In this article, we'll learn what global warming is, what causes it and what the effects could be. Not everyone is convinced that global warming is happening; and even if it is happening, some aren't sure it's something we need to worry about.
So what is global warming and how does it happen? To understand the global warming phenomenon, first we have to learn about the difference between weather and climate.
Weather and Climate
It's important to understand that when we talk about climate being long-term, we mean really long-term. Even talking about a few hundred years is pretty short-term when it comes to climate. In fact, changes in climate sometimes take tens of thousands of years. That means if you happen to have a winter that isn't as cold as usual, with not very much snow -- or even two or three such winters in a row -- that isn't a change in climate. That's just an anomaly -- an event that falls outside of the usual statistical range but doesn't represent any permanent, long-term change.
It's also important to understand that even small changes in climate can have major effects. When scientists talk about "the Ice Age," you probably envision the world frozen, covered with snow and suffering from frigid temperatures. In fact, during the last ice age (ice ages recur roughly every 50,000 to 100,000 years), the earth's average temperature was only 5 Celsius degrees cooler than modern temperature averages.
Global warming is a significant increase in the Earth's climatic temperature over a relatively short period of time as a result of the activities of humans.
In specific terms, an increase of 1 or more Celsius degrees in a period of one hundred to two hundred years would be considered global warming. Over the course of a single century, an increase of even 0.4 degrees Celsius would be significant.
The Greenhouse Effect
You can think of the Earth sort of like your car sitting out in a parking lot on a sunny day. You've probably noticed that your car is always much hotter inside than the outside temperature if it's been sitting there for a while. The sun's rays enter through your car's windows. Some of the heat from the sun is absorbed by the seats, the dashboard and the carpeting and floor mats. When those objects release this heat, it doesn't all get out through the windows. Some is reflected back in -- the heat radiated by the seats is a different wavelength than the light of the sun that made it through the windows in the first place. So a certain amount of energy is going in, and less energy is going out. The result is a gradual increase in the temperature inside your car.
When the sun's rays hit the Earth's atmosphere and the surface of the Earth, approximately 70 percent of the energy stays on the planet, absorbed by land, oceans, plants and other things. The other 30 percent is reflected into space by clouds, snow fields and other reflective surfaces [ref]. But even the 70 percent that gets through doesn't stay on earth forever (otherwise the Earth would become a blazing fireball). The things around the planet that absorb the sun's heat eventually radiate that heat back out. Some of it makes it into space, and the rest of it ends up getting reflected back down to earth when it hits certain things in the atmosphere, such as carbon dioxide, methane gas and water vapor. The heat that doesn't make it out through Earth's atmosphere keeps the planet warmer than it is in outer space, because more energy is coming in through the atmosphere than is going out. This is all part of the greenhouse effect that keeps the Earth warm.
Global Warming: What's Happening?
Carbon dioxide (CO2) is a colorless gas that is a by-product of the combustion of organic matter. It makes up less than 0.04 percent of Earth's atmosphere, most of which was put there by volcanic activity very early in the planet's life. Today, human activities are pumping huge amounts of CO2 into the atmosphere, resulting in an overall increase in carbon dioxide concentrations. These increased concentrations are considered the primary factor in global warming, because carbon dioxide absorbs infrared radiation. Most of the energy that escapes Earth's atmosphere comes in this form, so extra CO2 means more energy absorption and an overall increase in the planet's temperature.
The Worldwatch Institute reports that carbon emissions worldwide have increased from about 1 billion tons in 1900 to about 7 billion tons in 1995. The Institute also notes that the average surface temperature of Earth has gone from 14.5 degrees C in 1860 to 15.3 degrees C in 1980.
Nitrous oxide (NO2) is another important greenhouse gas. Although the amounts being released by human activities are not as great as the amounts of CO2, nitrous oxide absorbs much more energy than CO2 (about 270 times as much). For this reason, efforts to curb greenhouse gas emissions have focused on NO2 as well. The use of large amounts of nitrogen fertilizer on crops releases nitrous oxide in great quantities, and it is also a by-product of combustion.
Methane is a combustible gas, and it is the main component of natural gas. Methane occurs naturally through the decomposition of organic material and is often encountered in the form of "swamp gas." Man-made processes produce methane in several ways:
What will actually happen if the entire planet warms up a few degrees? Read the next section to find out.
Effects of Global Warming: Sea Level
Glaciers and ice shelves around the world could begin to melt. In fact, this is already happening. The loss of large areas of ice on the surface could accelerate global warming because less of the sun's energy would be reflected away from Earth to begin with (refer back to our discussion of the greenhouse effect). An immediate result of melting glaciers would be a rise in sea levels. Initially, this would only be an inch or two (however, if the West Antarctic Ice Sheet were to melt and collapse into the sea, it would push sea levels up 10 feet, and many coastal areas would completely disappear beneath the ocean). Sea levels would also rise because ocean waters would grow warmer, causing the water to expand. Even a modest rise in sea levels could cause flooding problems for low-lying coastal areas.
With a rise in the overall temperature of the ocean, ocean-borne storms such as tropical storms and hurricanes, which get their fierce and destructive energy from the warm waters they pass over, would increase in number and force.
Effects of Global Warming: Seasons and Ecosystems
The most devastating effects, and also the hardest to predict, would be the effects on the world's living ecosystems. Many ecosystems are very delicate, and the slightest change can kill off several species as well as any other species that depend on them. Most ecosystems are interconnected, so the chain reaction of effects could be immeasurable. The results could be something like a forest gradually dying off and turning to grassland or entire coral reefs dying. Many species of plants and animals would adapt or move to deal with the shift in climate, but many would become extinct.
The human cost of global warming is hard to quantify. Thousands of lives per year could be lost as the elderly or ill suffer from heat stroke and other heat-related trauma. Poor people and underdeveloped nations would suffer the worst effects, since they would not have the financial resources to deal with the problems that come with an increase in temperature. Huge numbers of people could die from starvation if a decrease in precipitation limits crop growth and from disease if coastal flooding leads to widespread water-borne illness.
Next, we'll find out why some people aren't concerned about global warming.
Is Global Warming a Real Problem?
What's the correct answer? It can be hard to figure out. Most scientists will tell you that global warming is real and that it is likely to do some kind of harm, but the extent of the problem and the danger posed by the effects are wide open for debate.
In the next section, we'll see if there's anything we can do to help prevent global warming.
Can We Stop Global Warming?
Here are some other specific ways you can help decrease greenhouse-gas emissions:
To really stem the emission of greenhouse gases, we need to develop non-fossil fuel energy sources. Hydro-electric power, solar power, hydrogen engines and fuel cells could all create big cuts in greenhouse gases if they were to become more common.
At the international level, the Kyoto treaty was written to reduce CO2 and other greenhouse gas emissions worldwide. Thirty-five industrialized nations have committed to reducing their output of those gases to varying degrees. Unfortunately, the United States, the world's primary producer of greenhouse gases, did not sign the treaty.

On Sunday afternoon, a wildfire began burning south of U.S. 41 and west of Krome Avenue, said Scott Peterich, a wildfire mitigation specialist with the Florida Forest Service. The fire was consuming about 400 acres before it moved into the fringes of Everglades National Park.
“The communities are probably going to smell smoke because of the wind,” Peterich said.
The wind Monday morning was blowing out of the southwest at about 8 mph and, according to the National Weather Service, is expected to become very strong during the day as temperatures soar to near record levels.
Other wildfires were also burning Monday.
Helicopter images broadcast by WSVN-Ch. 7 showed plumes of smoke coming from scrub land south of Kendall Drive and west of Krome Avenue (Southwest 177th Avenue).
People reported smelling smoke Monday as far north as Fort Lauderdale.
The immediate weather conditions will not do much to diminish the smell of smoke or help contain the fires.
Monday’s high temperature will be near 93. The record high for Fort Lauderdale on April 20th is 90, which happened in 2006.
In a special weather statement, the weather service said southwest winds will peak at 15 to 25 mph today with gusts nearing 30 mph.
Because of the lack of rain, the region’s “Fire Danger Index” is level 4 or “Very High” on a scale of 1 to 5, according to the state forest service.
There could be some slight relief on Tuesday when a 30% chance of showers moves in and the predicted high temperature drops to 88.


Improving New Zealand's weather forecasting ability
A team of meteorologists at NIWA, led by principal scientist Dr Michael Uddstrom, have been looking into how to improve weather forecasts for New Zealand. The team has been developing a new numerical weather prediction model for the country that will be much more capable of representing the unique features of our environment, such as the geography of the Southern Alps.
What is NWP?
Numerical Weather Prediction (NWP) is a term used to describe the use of computer modelling to predict the weather. More formally, the intention of NWP is to predict the future state of the atmosphere using data gathered from observations of its current state and the application of a set of numerical approximations to the equations of fluid dynamics and physical processes. Those processes include convection, boundary layer turbulence, radiation, cloud physics, microphysics and orographic drag.
A NWP forecast is thus made possible by four broad components:
- a numerical model that describes how the atmosphere behaves
- observation data
- a means of inserting that observation data into the model to generate the best possible initial condition, and
- a computer of sufficient power to be able generate a forecast sufficiently quickly for it to be useful.
For the last few years, NIWA has operated the New Zealand Limited Area Model, or NZLAM. This model is a local configuration of the UK Met Office Unified Model. In NZLAM, New Zealand and its surrounding seas are divided onto a 324x324 horizontal grid, while the atmosphere is split into 70 vertical levels, from the surface to approximately 80km above sea level. Each horizontal grid square is about 12km (0.11 degrees) in length.
Figure 1 An illustration of an NWP Limited Area Model domain showing how it is discretized into a horizontal (x, y) grid, vertical layers (z) - which near the surface are terrain following, but become smoother with height. (Courtesy of the UCAR COMET programme.)
Observational data for New Zealand’s atmosphere is typically provided via satellite, in particular from instruments on board NOAA-14 and NOAA-15. Additional data are provided from ship, airplane readings and weather stations from around the country.
These data are then inserted into the model using a process called data assimilation, where the model state from a previous forecast is altered to include the new observations and becomes the initial state for the next forecast. During the course of this assimilation process, a number of processing, data cleansing and bias correction steps are carried out to ensure no erroneous data is included that could lead to problems running the model. For the NZLAM, the initial conditions comprise 86 different meteorological variables, with 18 of those having values covering the lowest 80km of the atmosphere, 4 containing data for the 2m of soil directly below the surface and the rest being valid only at the surface.
NeSI is essential for the fourth component of NWP. The computing platforms, in particular the synergy of many processors, large amounts of memory and extremely fast interconnects, enables a 2-day forecast to be produced within minutes. On FitzRoy, a typical 2-day NZLAM forecast takes approximately 11 minutes to complete, using 256 processors across 8 nodes.
There is a difficult trade off in NWP between accuracy and speed. A more accurate model is much more computationally intensive. With access to HPC facilities through NeSI, NIWA is able to increase the accuracy of the modelling while retaining the speed necessary for effective planning.
A finer grid enables the model to more accurately represent the topography of the region of interest and the surface processes occurring at the smaller spatial scales. Unfortunately, as the number of grid points increases, so does the number of calculations and the communication overhead that is imposed between each region to progress to the next step in the simulation.
While the process of developing a new model may sound simple – simply divide the area of interest into smaller pieces – there are a number of factors which make this an extremely challenging task. For example, the numerical approximations, or parameterisations, of physical processes that could be applied at the 12km scale in NZLAM may no longer be applicable or even needed at these finer scales. Thus new parameterizations may be required, or in the case of convection, it may be possible to dispense with the need to use a parameterisation scheme altogether and explicitly model this process. Going one step further, for groundwater and soil temperature calculations to be accurate, a new land surface process model which is coupled to the NWP model, is used.
The data assimilation and observation processing techniques must also be developed to copewith the additional detail that the finer resolution NWP models are capable of producing. All of these changes and developments are verified against actual observations and compared against forecasts from the coarser resolution forecasts over a series of case studies to identify any local bias in the model and ensure that there really is a benefit to using the finer resolution.
Figures 2-4 Images showing how the topography of the South Island as used in an NWP model varies at horizontal resolutions of 12km (left), 4km (centre) and 1km (right) horizontal resolutions. At 12km, resolution, Mt Cook has a peak height of just 1675m (cf 3754m in reality) and the Southern Alps is a continuous ridge, while at 1km, Mt Cook now stands at 2820m above sea level and the glacial valleys, fjords and basins that litter the Southern Alps can be better resolved.
In parallel to NZLAM, NIWA has recently begun running a 1.5km resolution NWP model called the New Zealand Convective Scale Model (NZCSM). This model uses initial conditions interpolated from NZLAM onto a 1.5km grid. This first guess is then adapted to match up-to-date observation data. The domain is divided into a horizontal grid of 1200x1350 1.5x1.5km squares and has 70 vertical levels that cover the lowest 40km of the atmosphere. This resolution produces a model 15 times larger than NZLAM computationally, but still only covers a much smaller geographic area. It also requires a lot more computational power to produce a forecast in a timely manner. Currently, a 36 hour forecast by NZCSM takes 130 minutes to complete using 810 processors spread across 13 nodes of FitzRoy. The resolution difference between those two models means that while they will both be able to predict which cities will be affected by storms, NZCSM should be able to predict which suburbs will be heaviest hit.
Figure 5 10m surface wind gusts showing outflows from South Island fjords.
One of the biggest challenges in NWP is verification. While forecasts at finer resolutionsmay look more detailed and realistic, that does not mean they are necessarily more accurate. At NIWA, a lot of effort is currently being put into ensuring that forecasts from NZLAM and NZCSM are properly verified against local observations of key meteorological variables. These include precipitation, wind speed and direction, temperature, relative humidity and mean sea level pressure. Proper verification of precipitation is vital as model resolutions increase due to the greater spatial variability of the field and the effect that the local topography can play in where precipitation occurs. For this reason, effort is put into regional, rather than just location-specific verification and novel, spatially-aware verification techniques are being developed.
Why is this work important?
In its current form, NZLAM is unable to adequately resolve important features of New Zealand’s unique landscape, such as the Southern Alps. More accurately representing the geography, soil conditions and other physical processes that affect the weather will all combine to improve the accuracy of NWP in New Zealand.
As well as providing improved accuracy generally, finer resolutions also enable far better modelling of severe weather events. A mesoscale model, that is a model with a horizontal resolution of about 12km (such as NZLAM), typically relies on statistical approximation to represent atmospheric convection processes, including precipitation. At finer resolutions, atmospheric convection is able to be modelled explicitly. Coupled with improvements in the representation of the topography, this should lead to more accurate modelling of severe weather for both national and local forecasts.

What is Humidity?
Easily said, humidity is just the sum of water vapor held in the atmosphere. Since the air temperature rises, more water vapor could be held because molecules’ motion in higher temperatures prevents moisture from occurring.
There are 3 chief dimensions of humidity: relative, complete, as well as specific.
The greater the total amount of water vapor, the greater the total humidity. By way of instance, a maximum of approximately 30 g of water vapor may exist at a cubic meter volume of air temperature from the middle 80s.
Relative humidity, expressed as a percentage, indicates the quantity of water vapor that air is holding about the amount it can hold at a certain temperature. Warm air can have additional water vapor (moisture) than cold air; therefore, with all exactly the identical quantity of absolute/specific humidity, air will probably have greater relative humidity. Relative humidity of 50 percent signifies that the air keeps on this day (specific temperature) retains 50 percent of the water required for the atmosphere to be soaked.
Hence the relative humidity of the atmosphere is a function of the water content and temperature.
Complete and humidity are rather similar in theory.
What is Dew Point?
The higher the dew point increases, the larger the quantity of moisture from the atmosphere.
What is the relationship between Dew Point and Relative Humidity?
Compared with relative humidity, the dew point is often cited as a more precise method of measuring the atmosphere humidity and relaxation because it’s a complete dimension (unlike relative humidity).
In case the temperature drops any farther, condensation will end up, and liquid water will start to form.
When the relative humidity is 100 percent (i.e., dew point temperature and real air temperatures are the same), this doesn’t automatically signify that precipitation will happen. It only suggests that the maximum quantity of moisture is in the atmosphere at the specific temperature that the atmosphere is at. Saturation might come in fog on the floor and clouds aloft (which include water droplets suspended in the atmosphere ).
While dew point provides you a fast notion of moisture content in the atmosphere, relative humidity doesn’t because it is relative to the atmosphere temperature. To put it differently, relative humidity cannot be determined from understanding the dew point; the true air temperature also has to be known.
The relative humidity can be about the proportion of the real into the saturation vapor pressure.
Real vapor pressure is a measurement of the quantity of water vapor at a volume of atmosphere and increases as water vapor increases.
Saturated vapor pressure is the maximum VP that could exist at any given temperature.
Air, which can be at 100% relative humidity (RH), comprises water vapor that the VP is its own SVP in the specified temperatures. This contrasts with the atmosphere, which can be in equilibrium with liquid water. ‘Dry’ atmosphere will include water vapor using a VP that can be significantly less than the SVP in the specified temperature.
How is humidity measured?
The easiest hygrometer – a sling psychrometer – includes two thermometers mounted using a string handle. 1 thermometer is normal. Another has a fabric wick over its own bulb and can be referred to as a wet-bulb thermometer.
How does a psychrometer measure relative humidity?
One is sterile (often known as the dry bulb thermometer) and measures the true air temperature. Another, known as the wet-bulb thermometer, has a moist cloth in the tip. As water molecules evaporate on the wet-bulb surface, they will choose the heat together, lowering the valve’s reading. The rate of evaporation is dependent upon the vapor pressure or quantity of water vapor from the atmosphere. In 100% relative humidity, no water will vanish from the wet-bulb, and also, the readings on the thermometers will be the same. Assessing the 2 temperatures at a graph will provide the relative humidity.


World’s first year-long breach of key 1.5C warming limit
For the first time, global temperatures have surpassed the 1.5C warming limit, according to the EU’s climate service. This is by far the warmest period since modern records began– and likely for much longer.
Limiting long-term warming to 1.5C above pre-industrial levels – before humans started burning large amounts of fossil fuels – has become a key symbol of international efforts to tackle climate change.
Read the article to learn more about why we have broken pass the 1.5C limit and what this means for the future.


Abstract: This cross-national study employs a time-series cross-sectional Prais-Winsten regression model with panel-corrected standard errors to examine the relationship between renewable energy consumption and economic growth, and its impact on total carbon dioxide emissions and carbon dioxide emissions per unit of GDP. Findings indicate that renewable energy consumption has its largest negative effect on total carbon emissions and carbon emissions per unit of GDP in low-income countries. Contrary to conventional wisdom, renewable energy has little influence on total carbon dioxide emissions or carbon dioxide emissions per unit of GDP at high levels of GDP per capita. The findings of this study indicate the presence of a “renewable energy paradox,” where economic growth becomes increasingly coupled with carbon emissions at high levels of renewable energy, and the negative effect of economic growth on carbon emissions per unit of GDP lessens as renewable energy increases. These findings suggest that public policy should be directed at deploying renewable energy in developing countries, while focusing on non-or-de-growth strategies accompanied with renewable energy in developed nations.

Nairobi, 22 June 2009—A scientific paper, highlighting the need to accelerate action over a group of gases known as Hydroflurocarbons (HFCs) as part of the climate change agenda, was today welcomed by the head of the UN Environment Programme (UNEP).
The findings, by an international team of researchers are published in the Proceeedings of the National Academy of Sciences.
The scientists argue that HFC use could climb sharply in the coming years in products such as insulation foams, air conditioning units and refrigeration as replacements for ones being phased-out to protect the ozone layer.
Under a scenario where carbon dioxide emissions are pegged to 450 parts per million HFCs could equal nine Gigatonnes—equivalent to around 45 per cent of total C02 emissions-- by 2050 if their growth is unchecked.
Conversely, rapid action to freeze and to cut emissions annually alongside fostering readily available alternatives could see HFC emissions fall to under one Gigatonne by 2050.
Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said: “Dramatically cutting carbon dioxide emissions from society’s inefficient energy use is the key to catalyzing a transition to a low, carbon, resource efficient Green Economy. It is also central to delivering a stabilization of the atmosphere as outlined by the assessments of the Intergovernmental Panel on Climate Change”.
“But there are other low hanging fruit in the climate change challenge and this new scientific paper spotlights one of them—HFCs. By some estimates, action to freeze and then reduce this group of gases could buy the world the equivalent of a decades-worth of C02 emissions,” he added.
The projected growth in production and consumption of HFCs is in part linked with the success of the UNEP-administered Montreal Protocol on substances that deplete the ozone layer.
Since the late 1980s, this treaty has successfully phased-out 97 per cent of 100 chemicals that damage the protective shield that filters out harmful ultra violet rays to the Earth.
Over recent years, research has outlined that global efforts to protect the ozone layer has also delivered climate benefits as many of the chemicals that damage the ozone layer—such as chloroflurocarbons or CFCs-- also cause global warming.
In 2007 a scientific paper calculated the climate mitigation benefits of the ozone treaty as totalling an equivalent of 135 billion tonnes of C02 since 1990 or a delay in global warming of seven to 12 years.
In that same year countries meeting in Canada, under the Montreal Protocol, agreed to an accelerated freeze and phase-out of Hydrochloroflurocarbons (HCFCs)—chemicals designed to replace the old, more ozone-damaging CFCs—in the main for the climate benefits.
The new paper indicates that unless there is action on HFCs, then countries and companies are likely to pick this group of gases to replace HCFCs in products such as air conditioning units, refrigeration and insulating foams.
Guus Velders of the Netherlands Environmental Assessment Agency, the lead author, said in a statement: “Our team of scientists calculates that HFCs present a significant threat to the world’s efforts to stabilize climate emissions”.
“Because of the projected growth of these climate-warming chemicals, they could represent up to 45 per cent of the total global C02 emissions by 2050 under a scenario that stabilizes C02 emissions at 450 parts per million. Preventing strong growth in HFC use is an important climate mitigation option the world has now”.
Under a business as usual scenario, where C02 emissions are higher, HFCs could equate to between nine and 19 per cent of C02 emissions in 2050 causing a greenhouse effect equal to 6-13 years of global C02 pollution.
In 2008, governments requested the executive secretaries of the Montreal Protocol and the UN Framework Convention on Climate Change—Marco Gonzalez and Yvo de Boer-- to cooperate more closely including on the issue of HFCs and that cooperation is on-going.

12/26/2022 - 5:20PM - Merry Christmas to all! I have received and installed a second new webcam for my homepage (see above)! One cam in own is at my parents home in Leeds, ME still, while this new cam is from my house in Manchester, ME. Both cams will auto-refresh on this page once every 2 minutes.
12/13/2022 - 6:27PM - We may have our first snowstorm of the season on its way! Right now it still has a chance to mix with rain! Stay tuned for updates!
12/05/2022 - 9:09AM - After nearly a full week into December and we still don't see any significant chances of cold or snow in the forecast for our area. The area lakes/ponds haven't even frozen up yet. Rain storms and mild temperatures continue to lead weather headlines. Maybe things will shift more wintry by mid-month. Some forecasting is signaling that may be the case! We an only hope!
11/23/2022 - 5:25PM - After a very mild beginning of November things have turned much colder. We saw our first snow last week (1.7"), but that has since melted away. Slightly warmer temps will move in this coming weekend just in time for a storm which is now looking like a rain and wind storm. We're hoping more signinicant snow will be here soon!
10/24/2022 - 10:08AM - We continue to stay mild and rainy, with another 1" - 2" of rain expected over the next 3 days. Hopefully temps will start to cool down soon so that we can start introducing snow chances into the forecast! Now that the fall foliage season has ended, it's onto the anticipation of the first snow.
10/15/2022 - 11:48AM - We received just under 6" of rain in yesterday's storm! Amazing! And our peak wind gust was 42MPH. We lost a lot of leaves from the trees but thankfully there is still a decent amount up, allowing us to enjoy the nice foliage color for a bit longer.
10/11/2022 - 5:03PM - Peak foliage for our area has now gone past, and with rain and wind on the way for Friday, we expect to see a significant amount of leaf drop. It's going to start looking a lot like November around here before too long. Numerous Frosts and a couple Freezes have put an end to our growing season as well.
9/21/2022 - 8:58PM - Happy last day of summer! I'm working on getting my webcam to upload to this website again, hopefully just in time for peak fall foliage season and then the winter snow!
8/20/2022 - 8:25PM - The first fall foliage report of the season will be September 14th! Be sure to check back on my 'Fall Foliage' page for updated details then.
8/08/2022 - 8:40PM - Another month has gone by, and it sure has been hot and dry! We're ready for cooler fall weather just around the corner!
7/08/2022 - 8:50PM - Well July 4th has come and gone, and before you know it it'll take the rest of the summer with it. The Fall foliage season will be here soon enough! My favorite time of the year is fast approaching!
6/24/2022 - 6:14PM - Warm temps will envelop our are this weekend with highs reaching the upper 80's. After last weeeknds 50's and even a low of 39F on the first day of summer, this upcoming heat will feel even worse as we are not ready for it in this area after dealing with the recent cool weather. But it could be much worse!
4/12/2022 - 6:48PM - High temps over the past 2 days have reached the low 60's, something we haven't seen since early last fall. It is a welcome sight! The weather pattern has been wet and will continue to be so over the coming week. April showers bring May flowers, so they say!
4/07/2022 - 7:21PM - Maple syruping season has now come to an end for our area. It turend out to be be a great year for syrup making, with many warm days and cold nights over the past month leading to good sap runs. Spring has arrived and things are thawing out nicely. Lakes in the area should start to melt and open up over the coming weeks.
3/07/2022 - 8:39AM - Things are starting to come back together on this website. Just a few more tweak and additions and it'll be good to go once again! Now just to figure out if I want to change the URL away from the old monumenthillweather.webs.com to something more like centralmaineweather theme...
3/04/2022 - 6:31PM - I've made good progress on updating this website. Need to still get new pictures of my new weather station setup, but that's proving more difficult to do during the winter with lots of snow on the ground and very cold temperatures. I'll keep working at it!
3/01/2022 - 8:34PM - As I find time, I'm continuing to update this website to reflect my new weather station location. Keep checking back for the final look!
2/28/2022 - 3:48PM - It looks like Webs.com has not deleted their websites yet, so I'm in the process of updating this webpage to accomodate my new weather station after my move to a new town here still here in Central Maine! Stay tuned and keep checking back here for updates!
7/12/2021 - 8:17AM - Well it's July 12th and Webs.com still hasn't disabled their websites yet, so this website remains active for now! Hopefully it stays up for good!
12/07/2020 - 3:53PM - We finally have internet back, so my weather data and webcams have resumed uploading to this website! Thankful for all the power and utility crews for their hard work getting power and communications restored!
12/06/2020 - 3:16PM - Looks like we are going to be without internet for a while sadly, so no weather data or webcam updates for a while on this website. Hopefully it'll be fixed soon, but right now priority is to get power back to those that don't have it. Still over 125,000 without power. There are trees, lines, and poles down everywhere around our area.
12/06/2020 - 6:22AM - We never lost power, but we still don't have internet, so my webcams and weather data are not uploading. Hopefully crews are out and get it fixed soon but we are thankful to still have power with over 200,000 outages statewide currently. We ended up with 7" of very heavy wet snow and a peak wind gust of 45MPH.
12/05/2020 - 7:59PM - This has been a decent storm so far. We haven't lost power yet but it keeps flickering. We have lost interent however so my weather data and webcams sadly aren't uploading to the website. Hopefully that comes back up soon!
11/30/2020 - 9:20AM - A good storm is on the way this afternoon through tomorrow morning. 2-3" of rain is expected with winds gusting 40-50MPH consistently through most of the night. We may lose power but I'll have this station data back up and running as soon as we get power back if we do lose it.
10/28/2020 - 8:17PM - We had our first snowflakes of the season today! Our high only reached 35F and we had on and off snow showers throughout the day with no accumulation. More snow and cold temps is on the way over the next few days.
10/26/2020 - 7:54AM - Sleet and freezing rain falling this morning. Some snow is possibly on the way later this week! Winter is fast approaching!
10/17/2020 - 8:36PM - Wow have we been getting some serious rain over the past 2 weeks. Over 2" today and a little under a week ago we got just under 2". After our drought summer it sure is a sight for sore eyes! Lots of snow fell just to our NW this morning as well! Winter is just around the corner!
9/30/2020 - 7:00PM - Quite the storm this morning. We lost power for about 6 hours today, and my data is a bit off for the day because of it. Our rainfall total for this storm was 1.30", and our peak wind gust was 53MPH!! A lot of the fall foliage has dropped from this wind and rain, marking the near end of the foliage season here in West-Central Maine. The oak trees are all that are really left to change and drop their leaves.
9/20/2020 - 7:08PM - Well, temps in the mid 20's the past 2 mornings and possibly again tonight and our growing season is over. Combined with the drought, we now have to worry about all this dead, dry fuel for wildfires, something we don't usually have to worry about too much here in New England. On the bright side the fall foliage is really starting to pop!!
9/15/2020 - 8:56PM - 32F this morning with plenty of frost! Cooler temps still coming up with weekend with widespread frost likely multiple nights, and daytime highs staying in the 50's and low 60's. This is my kind of weather. We could use some serious rain though! Fall foliage is now starting to pop in areas and will continue to progress over the coming weeks.
9/13/2020 - 9:15PM - 36F the other morning and light frost. Colder nights ahead over the next week. Fall temps look to be here. Now if we could just get some rain to relieve us of this terrible drought we're in!
9/08/2020 - 7:14AM - After cooler temps the past couple days (a low temp of 43 a few mornings ago), the next couple days will be back near 80F before 60's for highs return, with lows in the upper 30's and low 40's. Fall is close now!
8/29/2020 - 8:46PM - Wow, our first rain drops in over a month! We picked up a little under an inch of rain today, the first time we've had that much rain since this past spring! We need a lot more where that came from! Every little bit helps our current drought situation.
8/22/2020 - 6:16AM - It may finally be cooling off a bit around here. Our high temps have been running in the 70's with lows over the past couple morning dropping down into the mid 40's to low 50's! Much better! We are still in a drought though with no rain still in sight!
8/11/2020 - 9:01PM - It's still hot around here! Our high today was 90F with a high dew point of 73F! We are all anxious for fall weather here, and we need rain badly, but there is none in sight. Our drought continues to worsen. This has been the hottest and one of the driest summers on record for our area.
7/28/2020 - 7:41AM - Is fall here yet?! The summer heat and humidity continues for our area, and after a wet spell the last few weeks we are starting to dry out again. Anxious for cool, crisp weather!
7/04/2020 - 7:29AM - Happy 4th of July! After what was one of the driest May/June's in memory, we picked up nearly 4" of much needed rain over the past week! Showers and storms are possible multiple days this upcoming week. Hopefully we are out of that drought pattern!
5/26/2020 - 3:31PM - It seems as though we jumped right into summer from winter this year. Temps have been running in the 80's with some 90's farenheit plus increased humidity levels likely over the next few days! And we just had a heavy frost with a low temp of 31F just a few mornings ago!
5/09/2020 - 8:01AM - Well, it's May 9th and we have 3.0" of new snow on the ground currently and its still snowing at a good clip! Winter just doesn't want to let go this year!
4/20/2020 - 6:48AM - 60F felt great yesterday even though it was a bit breezy throughout the day. Cooler temps return for this week though as this cool spring continues. No real warmth in sight for us yet! It was 24F out of the past 3 mornings.
4/13/2020 - 8:33PM - My latest video on my YouTube channel covers footage I took of our most recent snowstorm that caused the tree damage and power outages in our area. Head on over and check it out. Like and subscribe to my channel The Maine Naturalist!
4/11/2020 - 3:22PM - Our power is back after 2+ days of it being out. Cleanup continues as we prepare for the next round of possible outages during the next storm which will contain rain and winds gusting possibly over 50MPH on Monday!
4/11/2020 - 5:56AM - Still no power. Lots of tree damage from the 12.5” of heavy wet snow we ended up getting. Hoping our power is restored at some point today. We’re extra thankful for a woodstove in times like these. Its a great source of heat and something to cook on!
4/09/2020 - 4:43PM - Very heavy snow falling right now, and its heavy wet snow. Already 3" and accumulating rapidly. We may lose power if this keeps up! 8-12" expected by the end of this storm!
4/04/2020 - 11:11AM - Finally a welcomed return to some sunshine today after clouds and rain over the last 4 days! We picked up 1.99" of rain over just the past 2 days, with winds gusting up to 40MPH as well. We all need the return to this nice spring weather right now.
3/21/2020 - 8:19PM - Most of the snow is now gone, and Maple Syruping season is winding down. It looks like winter isn't over just yet however. Windy and cold conditions will prevail through this weekend into early next week followed by what's looking like a plowable snow event for our area Monday night into early Tuesday.
3/09/2020 - 7:58PM - Wow! 60F today! That is crazy warm for this early in the season. Our snow is melting away fast. Most of it has melted out of the fields, and it's coming down fast in the woods too. With warm temps and a few shots at some rain over the next week, it will continue to melt away. Spring has arrived very early here in Western Maine!
3/07/2020 - 11:05AM - I continue to upload videos to my YouTube channel. Head on over and check them out! Here is the link to my most recent video! The Maine Naturalist
3/06/2020 - 7:58PM - The spring-like weather continues for our area. Its been crazy mild with little to no snow for weeks now. Our snow is melting away fast! It will be gone soon at this rate. The frost is already coming out of the ground here too. Earliest I ever remember it doing that.
2/27/2020 - 6:31PM - We didn't see much snow from this storm (a slushy coating is about all), but we did see over an inch and a half of rain and winds gusting 30MPH to 40MPH most of the day today. We did have wet snow falling for a good part of the day but the temp was in the mid 30's at the time which meant it didn't accumulate at all. Places just NW of us did see quite a bit of accumulation however, upwards of a foot in the higher elevations in western Maine.
2/24/2020 - 7:14PM - The Maple sap ran great over the past two days with high temps in the upper 40's to low 50's! This spring teaser felt great, and we have one more 'warm' day tomorrow before it starts to cool back down. We even have a decent snowstorm on the way for Thursday. Rain may mix in, but right now it's looking like at least 6" of snow is likely with more further inland and less towards the coast where more mixing with rain will occur. Stay tuned for updates as any shift in storm track could mean more or less snow!
2/22/2020 - 2:32PM - With the warm temps expected over the next several days we decided to tap our Maple trees. Syruping season 2020 has begun! They are running a bit today but should run good tomorrow and Monday. With plenty of snow on the ground and these warmer temps, outdoor winter activites are great right now, so get out there and enjoy! Another snow event is possible later this upcoming week. Stay tuned for updates!
2/15/2020 - 11:56AM - It sure was cold this morning! Our low temp was -16.4F, the coldest morning so far this winter. Some mountain and northern Maine valleys were around -30F! Brrr!
2/11/2020 - 8:49PM - After picking up 4" of new snow Monday morning, we have more on the way for Thursday. Another 4-8" is expected for our area.
2/09/2020 - 5:54PM - Some light snow is on the way for tonight into tomorrow morning. A general 1-3" is expected. A couple more chances of light snow through this upcoming week. No big storms in sight however, and no arctic cold after the past 2 days we've had.
2/07/2020 - 5:50PM - We ended up with 1/4" of ice accretion, 2" of pure sleet, and now it is snowing heavily and we've picked up 2" of snow since the changeover which happened about an hour ago. Looks like the storm is wrapping up however and other than wind and some drifting, it should be over within the next couple of hours.
2/07/2020 - 11:10AM - We picked up a decent coating of ice from freezing drizzle overnight last night, now it is heavy sleet falling. Hoping it changes back over to snow this afternoon before it all wraps up tonight. Lets see how much we get now that precipitation intensity is picking up!
1/26/2020 - 8:49AM - My new snow depth webcam is set up and uploading images to my Snowfall Page. Now I'm working on making a new snow depth stake which I should have in the webcam image by this afternoon. We lost some snow with the rain we received last night (1.08" of rain!), but we still have a good base snowpack which should freeze back up over the next few days. Now we just need more new snow, but nothing is in sight...
1/25/2020 - 1:09PM - My new webcam is now installed and is viewable on my Snowfall Page. I am working on building a bigger (easier to read) snow depth stake to put in the place of the one I currently have for better view ability from the webcam. Check back for that over the next couple of days!
1/24/2020 - 8:33PM - After getting the wrong webcam, I switched it out for the same one I already have been using and that one was delivered this evening, so over the next two days I hope to find time to get this new one set up and uploading images to this website in addition to the current webcam I have. I'm hoping to have this new one as a snow depth monitoring webcam during winter, and as a secondary cam during the warmer months.
1/19/2020 - 7:32PM - I've purchased and am awaiting the arrival of another webcam which I plan to use as a snow depth cam facing my snow stake which will allow for 24/7 monitoring of snow depth here in Leeds. During the warmer months I'll use it for another webcam view (or maybe to watch over our goats and horse barn. I'm hoping to have the camera set up and uploading to this website by next weekend.
1/19/2020 - 8:01AM - 5.5" of snow for this storm, and our snow depth is now up at a foot and a half. Outdoor winter activities (skiing, snowshoeing, snowmobiling, etc.) should be looking great for today and the foreseeable future as temps will remain very cold with no melting expected.
1/17/2020 - 8:45PM - 8.5" of snow yesterday and now we are under a Winter Storm Watch for another 6-10" tomorrow night through early Sunday. We are dealing with brutally cold temps as well which will last through the first half of next week. After a brief January thaw winter has returned.
1/12/2020 - 6:50AM - After mid 50's yesterday, cold air has taken longer to filter back into the area with the pouring rain this morning which has led to just plain rain instead of freezing rain like we were expecting (which is good news!). Because of the warm temps and rain most of our snowpack has melted away however. As the temp continues to fall (now down to 32F) we may see some light icing through the rest of the day, but nothing like we were expecting.
1/06/2020 - 2:59PM - Light snow has started to fall this afternoon. We should see an inch or two from this light event.
1/05/2020 - 8:45AM - We woke up to 2.2" of fresh snow this morning. Should be a great day for any outdoor winter activities with flurries in the air through the day. It will be a bit breezy but nothing too unbearable. A bit more snow is expected tomorrow evening (around 1"), and then another larger storm is possible mid-week.
12/31/19 - 5:42PM - A new video is out on my Youtube Channel! Maine White-tailed deer and Porcupine! Check it out, like, and subscribe to my channel. Thanks for your support! My next video (which will be out soon) will be a silence and solitude style hike in the woods here in Maine during todays snowstorm. Keep an eye out for that/subscribe to my channel so that you get automatically notified when I post a new video! The Maine Naturalist
12/31/19 - 2:35PM - We ended up with 10.5" of snow from this 2-part storm. Finally a decent snow with no mixed precipitation!
12/29/19 - 4:18PM - Snow is on the way but how much is still up in question. Right now we are under a Winter Storm Watch for an expected 6+", it could be up near 10" or as low as 3-4" depending on how strong the storm gets as well as if we see any mixing or not. We should remain dry through tomorrow and snow will overspread our area Monday night and last through most of Tuesday. Stay tuned for updates!
12/23/19 - 3:12PM - With the weather as quiet as it is right now I thought I'd share that a new video is now live on my YouTube channel and includes some great photos of the deer and coyotes that we have around our home here in Leeds, ME. Check it out! Follow the link to my channel 'The Maine Naturalist' and click on the most recent video you see! Enjoy the video! The Maine Naturalist
12/19/19 - 9:31PM - I just installed my new WeatherLink Live for data uploads to this website and CWOP/Weather Underground. Data should now automatically update on this page every minute without the need for you to manually refresh the page.
12/16/19 - 8:25AM - We had a peak wind gust yesterday of 47MPH. Colder air is now here and we should see some snow tomorrow afternoon/evening, though only a general 1-3" by the looks of it.
12/14/19 - 8:36PM - Wow! 2.51" of rain over the past 24 hours and it is still raining on and off! And with frozen ground the water had nowhere to go other than ponding up and running off into rivers and streams which are now flooding. Where did winter go?
12/10/19 - 8:57PM - A new video is out on my Youtube Channel! White-tailed deer everywhere! Check it out, like, and subscribe to my channel. Thanks for your support! The Maine Naturalist
12/10/19 - 8:55PM - Well the rain and warm temps took its toll on our snowpack which is completely gone now (other than a few piles left here and there). More rain this weekend and then snow possibly once again next week. Still plenty of time to get snow for a White Christmas.
12/08/19 - 7:48AM - 1°F this morning, not quite below zero yet. Believe it or not rain is on the way with temps in the 50's for the next few days! Most of our snowpack should melt before colder temps return after this upcoming warm-up.
12/03/19 - 8:41PM - We ended up with an additional 6.5" of snow today, bringing this storms 2-day total to 7.5". It looks and feels like winter out there now for sure!
12/02/19 - 8:20AM - We picked up a quick inch of snow last night (a bit unexpectedly as the snow was supposed to stay south of our area), but the main event should get started later today/tonight and last through tomorrow where we are expecting to see a general 6-10" before all is said and done. Check back for updates! In the meantime check out my YouTube channel for new video updates (follow the YouTube button on the left side of this homepage), some of which will go over weather here in Leeds, ME.
11/30/19 - 6:01AM - A snowstorm looks like it's on the way for Monday into Tuesday. Right now its looking like 4-8" for our area but this storm is very track sensitive and any shift in the current forecasted track could change those totals significantly, so check back for updates!
11/28/19 - 5:28AM - Happy Thanksgiving!
11/25/19 - 6:33AM - After heavy icing yesterday afternoon/evening temps warmed up to the mid 30's and most of the ice melted overnight. Winds have been gusting up near 30MPH all night. Nice weather will be with us the next two days before we watch the approach of our next storm for Wednesday night into Thanksgiving morning. Right now rain to snow looks likely with that one. Check back for updates!
11/24/19 - 4:11PM - We’re currently seeing heavy freezing rain with a good quarter inch of ice accretion already and the temp holding steady at 31F. Hoping it flips back to snow soon instead of this nasty freezing rain!
11/17/19 - 3:17PM - I've created a new Facebook page associated with my YouTube channel. Check it out here The Maine Naturalist
11/15/19 - 6:55AM - We ended up with 3" of snow from the last event. Some snow squalls are possible this evening as an arctic front passes through. After that cold air will be in place for the weekend, with another storm slated to arrive Monday. That looks to be another wintry mix event.
11/12/19 - 6:08AM - So far we've picked up 2.5" of new snow with a glaze of ice on top from the freezing drizzle we are currently seeing. Should see a change back over to a bit more snow later today.
11/11/19 - 6:11AM - Happy Veterans Day and Thank You to all who serve or have served our country!
11/10/19 - 8:45AM - A wintry mix to snow looks to be on the way for tomorrow PM through Tuesday. A few inches of snow is likely with arctic air for the days to follow.
11/08/19 - 6:41AM - We saw our first snowflakes of the season yesterday evening into overnight last night. It dusted the ground in spots, with more accumulation in the higher elevations to our north and west. Now cold air is in place and more significant snow is possible next week with even colder temps likely.
11/06/19 - 8:20PM - A general 1-2" of snow is expected for our area tomorrow night into early Friday. It will start as a cold rain tomorrow afternoon and change to wet snow in the evening. Accumulations will mainly be on grassy surfaces and the trees as the blacktop roads are still pretty warm. Watch out for black ice Friday morning however as temps do drop into the mid to upper 20's as the precipitaion winds down.
11/02/19 - 8:46PM - Our first accumulating snow of the season is possible later this week (Thursday night into Friday)! Stay tuned and check back here for updates.
10/29/19 - 9:04PM - We have yet another large storm on the way for Thursday through Friday. 1-2" of rain again with gusts winds over 40MPH is expected during that timeframe. It has been an active fall for sure. Hopefully this pattern keeps up once the temps cool off for good and it beocmes a snowy winter!
10/27/19 - 6:45AM - Another soaking is on the way for today through tonight. Around an inch of rain is expected with breezy conditions as well. Even some wet snow mixing with the rain in the higher elevations in Western Maine. It'll just be a raw chilly rain for most.
10/23/19 - 8:37PM - 2.38" of rain over the past 24 hours! Quite the soaker! More rain is on the way for Sunday into Monday as well. It has been a wet fall here, but I'm sure we will soon be talking about more 'White' in the forecast as the fall season deepens into winter.
10/18/19 - 5:49AM - We have power back on. We lost it for about 16 hours yesterday during the storm. We picked up 1.52" of rain but winds gusted around 50-60MPH which was enough to cause over 200,000 power outages across the southern and central part of the state yesterday. This morning still 120,000 homes are without power.
10/16/19 - 9:03AM - Forecasts are calling for 1-3" of rain and wind gusts to 50MPH for our area late tonight through the first half of tomorrow. Some power outages are possible. Be aware of flooded roadways from ponding during heavy rain, as well as slippery wet leaves on the roads as the wind and rain knocks them out of the trees.
10/15/19 - 6:36AM - Our first true Nor'easter of the season is on its way for Wednesday night through Thursday. This one will bring rain and wind. We'll have to watch for minor flooding and some power outages. At the very least the storm should knock down the rest of the fall foliage (with the exception of the oak trees which are just changing now).
10/7/19 - 9:19PM - Another new video is out on my YouTube channel covering a fall foliage update for our area as well as a hike in today's rain to set up my game camera. Check it out! (follow the link to my channel by clicking the YouTube button to the left or by following the link on my last note below).
9/30/19 - 8:33AM - New video out on my youtube channel covering a ride I took from here to Mt. Washington, NH checking out the early fall foliage color. Check it out on my YT Channel! The Maine Naturalist
9/26/19 - 8:20PM - The fall colors are really popping now. It should be near peak this weekend in Northern Maine and the mountains. We have another 1-2 weeks before we are at peak in our area. Keep checking the webcam above to see the color progress towards peak!
9/19/19 - 8:56PM - With a low temp early this morning of 28.7F our growing season is officially over. We covered plants but it was colder than expected so we lost some things we had covered as well. We will begin to warm up with the next few days seeing temps around 80F, something we haven't seen in a while. Maybe summer's last take? Time will tell...
9/18/19 - 5:28PM - A frost is likely tonight. We had some frost around early this morning but tonight will be colder with widespread frost a bigger possibility. Bring in or cover any plants (annuals) you want to keep alive later into the season.
9/15/19 - 8:45PM - Cool temps will be the rule over the next 3-4 days with highs in the mid 60's and lows in the upper 30's to mid 40's. Some light frost is possible in the colder valleys around our are both Tuesday night and Wednesday night this week. Fall officially begins next Monday the 23rd. Some color is starting to show now and will progress towards peak but the second week of October.
9/09/19 - 6:25AM - Our first sub 40F degree reading of the season this morning. Our low temp was 38.1F just a few minutes ago, and with the sun coming up now temps should begin to warm back up. Early tomorrow morning may even be a degree or two colder than this morning.
9/08/19 - 9:55AM - Other than some showers and a light NE breeze, we didn't see any impacts from Hurrican Dorian here. Now the weather will turn a bit cooler as fall creeps closer.
8/23/19 - 8:55PM - An early fall-like pattern will set up this weekend for our area with daytime high temps remaining in the upper 60's and nighttime lows dropping down into the 40's and even some 30's in the mountain valleys to our northwest. There will be a nice NW breeze each day as well making it feel even cooler at times. The leaves will start to change in the north Maine woods and mountains before we know it!
8/19/19 - 8:26AM - The beginning of the 2019 Fall Foliage season in Maine is now just a couple of weeks away! I will begin updating my Fall Foliage Page once daily beginning at the end of this month, lasting until early November. My favorite time of the year (next to Winter of course!). Don't forget to check back regularly to see the progression of color of the trees on my webcam on this homepage.
8/08/19 - 7:32AM - We received over half an inch of much needed rain last night, and a bit more is possible throughout the day today. Cooler temps will be the rule over the next week or so as well, a welcome change from the heat and humidity we had been seeing through most of July and early August.
8/05/19 - 12:33PM - There was a feel of fall in the air early this morning with low temps in the low to mid 40's in our area. Some mountain valleys just to our Northwest were in the upper 30's. We typically get our first frost in typically a little over a month from now. It definitely feels like late summer with warm, dry days and cool nights. We need rain however, it is very dry! Some rain is possible mid-week this week.
7/21/19 - 1:35PM - Today will be the last day of this excessive heat and humidity. Tomorrow will still be warm and a bit humid before some rain is likely tomorrow night. This upcoming week looks like great summer weather.
7/17/19 - 9:29PM - Tomorrow will be a beautiful day with low humidity and temps in the 70's, but then the real heat kicks in for this weekend. Saturday will be one of the hottest days we've seen in a long time, with high temps in the low 90's and dew points in the low to mid 70's. Not ideal weather for us Mainers at all. Thankfully we only have to deal with this a few times each summer.
7/14/19 - 9:20PM - The great summer weather continues on. Low temps have been cool at night with warm temps in the 80's during the day. We've had plenty of rain which is keeping things green. This coming week looks warm with numerous chances of showers and storms.
7/06/19 - 9:22PM - We had quite the storm again this afternoon with lots of lightning and very heavy rain. We received 1.31" of rain in 20 minutes, and although we did not lose power at our house many people around us did, with some damage reported and a large tree down across a nearby road due to a direct lightning strike. Thankfully these storms were the leading edge of much cooler, drier air which will be a nice change over the next few days.
7/02/19 - 9:33PM - It's amazing what just a few weeks can do. We are now in the middle of a stretch of summer hear (by Maine standards) with highs in the mid to upper 80's and dew points in the 60's. We are still seeing plenty of showers and t-storms however, but should stay dry over the next few days at least. Happy early 4th of July to everyone!
6/17/19 - 9:13PM - We have yet to have any summer heat, and haven't had any thunderstorms yet this year either. It has been a wet, cool spring, but the pattern seems to be finally warming up a bit and becoming drier, with rain now happening once every few days. Everything sure is green this year so far with all the rain we've received.
5/18/19 - 7:27AM - I'll be playing around with my webcam settings again over the next couple of days so the cam image on this page may not update for a little while. It'll be back up hopefully by early next week, but possibly as soon as later today.
5/14/19 - 7:02PM - It's mid-May and our high temp today was 43F! And on top of that we had some wet snow mixing in with the rain this morning! It has been such a cold, wet spring. It has to warm up at some point...
4/28/19 - 8:26PM - We finally saw a bit of sun today with some more sun on the way for tomorrow. It has been a very chilly and damp stretch over the past few weeks. But all of this rain should really help to green things up once the sun comes out and warms things up a bit more.
4/18/19 - 6:21AM - I moved my webcam from the second story window to underneath our back deck looking at our back yard. There were a couple reasons for this, but the biggest one was I wanted to be able to use the cameras IR nighttime function that it has, which I was not able to use where I originally had it because it was behind the glass window and would not work. Now it is mounted outside where it works and gives a good shot our our backyard day and night. Check it out at night when you get a chance. No lights are on for the image, it's just the Infrared image the camera produces.
4/14/19 - 6:58PM - Unless we get another rogue snow event, the 2018/2019 snowfall season has now ended. There will be no more updates to my snowfall page until next season unless we get more snow this spring. It was another season over 100"!
4/10/19 - 8:33PM - 2.0" of new snow last night and our snow depth made it back up just under a foot once again, here in almost mid-April! It looks and feels like winter still out there. The snow should melt away quickly over the next few days though with temps by Saturday possibly pushing well into the 60's! Spring has to come at some point.
4/08/19 - 5:32PM - Winter has returned! We've picked up 5.0" of snow so far today with a snow/sleet mix falling currently. Another 1-3" is expected tomorrow night, and then eyes will be on the potential for another snow event next Monday. It was almost 60F yesterday and now snow. Typical spring in Maine!
4/04/19 - 4:42PM - With the small bit of snow this AM we've surpassed 100" season snowfall total once again this year, and a bit more looks to be on the way for Friday night into early Saturday.
4/03/19 - 4:34PM - We had a bit of April snow this morning and now temps are well into the 40's! Its definitely spring in Maine. The snow is melting away fast, although out in the woods there is still 1-2'. It will go away pretty quickly over the coming weeks.
3/23/19 - 10:49AM - We picked up just over a half an inch of rain on top of the 1.2" of snow we received yesterday, which melted away that new snow and really started to deplete the snowpack in many areas. Most south facing hills and open areas are melting down fast. Today with sun and temps in the low to mid 40's we should see a decent amount of additional melting. It will be windy with NW gusts to 40MPH. Happy Maine Maple Weekend! Maine Maple Sunday is tomorrow, but many sugar houses are open today as well. Go to Get Real Maine for more info.
3/22/19 - 6:20AM - Today's storm is trending colder and now we could see 1-3" of wet snow. Even though it will begin to warm into the mid 30's we may still see big wet snow falling but after about noon we shouldn't see much more additional accumulation. Liquid equivalent with this storm will be in the 1-2" range. Winds will be gusty out of the East as well.
3/14/19 - 8:44AM - I just put button links to my Weather Facebook page and my YouTube Channel on this homepage and at the bottom of my About page. Please check them out, like and subscribe as I will be doing my best to post new updates on the FB page and new videos on the YouTube page any chance that I get!
3/14/19 - 7:39AM - We picked up more snow last night than expected. We received 3.5" of fresh snow when we were only expecting a coating at most. Snow depth is at 27.5" now. Winter won't let go! Temps should warm into the mid to upper 40's the next 3 days however which should start some good melting.
3/04/19 - 1:54PM - We picked up 5.5" of new snow in this most recent storm, and our current snow depth is now up over 30". The warmer March sun feels great when it does come out, and we will likely be tapping our maple trees very soon once things warm up enough. There's a lot of snow on the ground this syruping season again!
2/25/19 - 6:44AM - We picked up another 1.5" of snow this morning in snow squalls. Now we wait for the wind to pick up!
2/24/19 - 5:14PM - We saw snow to a mix of sleet and freezing rain today with 2.0" of accumulation. It is now freezing drizzle with a temp sitting at 32F. The next weather headline will be high winds tonight through tomorrow. We will see westerly wind gust exceed 50MPH over the next 24 hours which may lead to power outages. A Wind Advisory has been issued for this reason.
2/15/19 - 5:37PM - It stayed colder than expected today and for that reason we received more snow then expected. We picked up 2.5" before the changeover to freezing rain/drizzle, which is still falling at this time. Temps are still around 30F. It was supposed to get up into the low 40's today! Guess not! Good news for winter sports for this upcoming week. 2+ft of snow on the ground going into the weekend!
2/14/19 - 9:34AM - Another 1.1" of snow last night from snow showers/squalls through the night. Snow depth is now just over 2 feet. Great snowpack heading into school vacation week for all outdoor winter activities. Snowmobile trails are great and skiing is at its best right now with comfortable temps expected over the next week as well. The Turner Ridge Riders One Lunger 100 race is in two days! See the Turner Ridge Riders Snowmobile Club tab below (to the left side of this page) for more info.
2/13/19 - 5:26PM - We ended up with a solid 10.0" of snow with this storm. We had some sleet mix in at times but it remained mainly snow for the entire storm.
2/10/19 - 6:47PM - Our next snowstorm is on the way for Tuesday night through the first half of Wednesday. We should see 8-12" with this one. Hoping this one stays all pure snow, with most storms so far this year mixing with sleet/freezing rain. It has been a very odd winter. Stay tuned for updates.
2/06/19 - 7:54PM - Wow! Almost 60F yesterday (59F to be exact!), and now over the next 36 hours we will be seeing nearly all types of possible precipitaion, with snow/sleet tonight (1-3"), a lull with spotty freezing drizzle tomorrow, and then heavier sleet/freezing rain and then rain tomorrow night into Friday morning. A Winter Weather Advisory has been issued for this reason.
1/28/19 - 5:06PM - A Winter Storm Warning has now been issued for our area for tomorrow evening through Wednesday morning for 6-10" of snow. Plan on a messy Wednesday morning commute.
1/25/19 - 3:55PM - Over the past 36 hours we picked up 2.06" of rain!!! It really put a dent in our snowpack and made everything wet with flooding all around. Now things are freezing back up solid which is making quite a mess. We need new snow on top of this ice to freshen the winter sports back up. Maybe next Tuesday/Wednesday. Stay tuned!
1/20/19 - 12:20PM - Precip has now changed over to mainly sleet, and the wind is picking up as well. We've picked up 11.0" so far but lots of drifting is making it hard to measure, and with sleet falling now additional accumulation will be minimal unless it changes back to snow. We're hoping the sleet changes back to snow soon!
1/17/19 - 7:50PM - A Winter Storm Watch has now been issued for our area for 7PM tomorrow through 7PM Sunday evening. Forecasts right now are calling for anywhere between 1-2 feet of snow before all is said and done with this storm. Blizzard-like conditions are possible during the day Sunday. Stay tuned over the coming days for forecast updates.
1/16/19 - 6:50PM - It's looking more and more likely that a foot or more of snow is on the way for Saturday night through Sunday, with strong winds and very cold temperatures. Blizzard like conditions are looking possible. Stay tuned to the forecast over the coming days for updates to the forecast.
1/14/19 - 8:08PM - We've fallen below 0F for the past few nights and may once again tonigh. Some light snow (2-4") is on the way for Friday, but all eyes are on the possibility of a major snowstorm for our area for this weekend (Saturday night through Sunday). Stay tuned for updates!
1/09/19 - 7:51PM - We woke up to a heavy glaze of ice on everything this morning followed by a few more inches of snow that fell during the day today. Now temperatures are dropping and the wind is ramping up and will gust up to 40MPH tomorrow as temperatures continue to plummet for the next few days. With all of the icing and wet snow today my anemometer is frozen up currently. I'm hoping it thaws out enough to start spinning again tomorrow. Until then, no wind readings will show up.
1/08/19 - 8:06PM - We received 2.0" of snow this morning before the precip tapered to just freezing drizzle for the remainder of the day today. Now we are seeing sleet and freezing rain with temps holding in the mid 20's. This will continue into tomorrow AM before changing back to snow where we could see another 3-6" before all is said and done. Then the wind picks up Thursday and arctic air moves in after that for a few days.
1/03/19 - 5:04PM - We picked up 3.8" of snow this morning and now we're keeping an eye on the possibility of a major Nor'easter Tuesday/Wednesday of next week. Stay tuned for updates!
1/01/19 - 5:14AM - Happy New Year! We started off the new year with 4" of snow before things warmed up and it melted down a bit. More light snow is on the way for Thursday (1-3"). It is quite windy out there as well with a peak gust today of 41MPH.
12/29/18 - 5:14AM - We never made it above freezing yesterday or last night and have about 1/4" of ice accretion on everthing this morning, with accretion still building as we are seeing freezing fog currently and a temp sitting between 30-31F. Temps should spike this morning to around 40F before falling through the day on stiff NW winds.
12/28/18 - 12:24PM - We picked up 3.0" of new snow this morning before things changed over to sleet and now freezing rain with a current temp of 27F. It will continue to warm up through the day and any freezing rain will change over to plain rain by days end. No big snow or brutal cold in sight.
12/25/18 - 8:43AM - Merry Christmas to all!
12/22/18 - 6:55PM - We picked up 1.73" of rainfall over the past 2 days and nearly all of our snowpack has melted away from the rain and temps in the 50's the past 2 days! It looks like a green Christmas for us this year! It will be cold going forward though, but no snow in sight until possibly next Thursday. Stay tuned for updates!
12/20/18 - 6:36AM - A Winter Weather Advisory has now been issued for our area for freezing rain tonight into about mid-morning tomorrow morning, for 0.10" to 0.25" of ice accretion before temps warm up and things change over to plain rain. We are expecting to see 1"-3" of rain with this next storm and temps possibly near 50F! Gusty SE winds will be an issue Friday night as well. A Flood Watch has been issued for rapid rises of area streams and rivers due to the heavy rainfall and rapid snowmelt. This storm may completely wipe out our current snowpack making for a green/brown Christmas this year.
12/15/18 - 7:55PM - Temps have moderated over the past day or two and will remain warmer over the next week. Some light snow is likely on Monday, and then we may see a rain storm :( come next Friday. That won't be good for our current snowpack leading into what was originally looking like a White Christmas, but may not end up being so if that forecast holds. We will see...
12/10/18 - 8:08PM - The cold weather continues with lows running in the single digits F and highs making it only into the teens and low 20's. It will remain quiet as well with our next storm not expected until possibly this coming weekend, and temps may end up warming up just in time for that storm to arrive, leading to a messy mix and rain! What an odd winter it has been so far.
12/05/18 - 8:14PM - Mid-winter cold temperatures will continue over the next week but no storms are in sight. Long range models point to a warm-up by mid-month with high temps possibly making it into the 40's for a while. We'll have to wait and see if this holds true. If so, our current snowpack could be in jeoprady of melting away before Christmas. It sure doesn't feel like it will right now however with a temp sitting at 15F as I write this.
11/30/18 - 7:58PM - More messy weather is on the way for tomorrow night into Sunday. We are expecting 1-2" of snow before things change over to sleet and freezing rain, and then plain rain by mid-morning on Sunday. We won't see much rain, but enough to make our current snowpack very wet. More melting on Monday followed by the return to winter thereafter.
11/27/18 - 4:37PM - Our snowfall total is 7.2", and although some rain/snow is still falling and will likely flip back to plain snow before the precip wraps up tonight, not much more accumulation is expected.
11/27/18 - 8:17PM - Snow has begun to fall here in Leeds. We are expecting anywhere from 5-10" by tomorrow afternoon when this storm wraps up. I am away from home for the majority of the day tomorrow but will be home to update snowfall totals in the evening.
11/25/18 - 3:32PM - After snow freezing rain this morning and warmer temps near freezing today, We become more wintry beginning tomorrow. A Winter Storm Watch has now been issued for our area for 8" to 14" of snow tomorrow evening through Tuesday evening. Stay tuned for updates!
11/22/18 - 8:30PM - Happy Thanksgiving! It sure doesn't feel like Thanksgiving around here as we have set a new record low temp for this date (2F) and a new record low high temp for this date (12F)! With winds gusting to 30MPH+ all day we had lots of drifting snow and wind chills well below 0F all day. It feels more like January!
11/21/18 - 6:19PM - We picked up 4.2" of snow yesterday and then another 1.2" this evening in the snow squalls that passed through. They were intense, with gusty winds as well. Now the arctic air is moving in!
11/19/18 - 6:01PM - A Winter Weather Advisory has now been issued for our area for 3-6" of snow tomorrow morning through tomorrow evening. Stay tuned for updates!
11/15/18 - 7:35AM - A Winter Storm Warning has now been issued for our area for 6-10" of snow tonight through tomorrow afternoon. Stay tuned for updates! Meanwhile, our low temp this morning was 9.1F! Winter has definitely arrived!
11/14/18 - 3:48PM - We are now under a Winter Storm Watch for our Snowstorm expected on Thursday night into most of the day Friday for 6-10" of snow possible. Stay tuned for updates!
11/13/18 - 6:37PM - We picked up another 2.5" of new snow this morning before things changed over to some freezing rain and then plain rain (1.36" of liquid equivalent). We are now under a Wind Advisory for tonight through tomorrow for strong NW winds up to 50MPH. Tomorrow will be brutally cold for this time of the year.
11/10/18 - 5:35AM - 2.0" of new snow overnight. Now just rain showers and gusty winds this morning. Winds will ramp up even more this PM and turn towards the west.
11/06/18 - 4:52AM - Today will be damp and chilly, then a warm day tomorrow before things start to cool off. Next week the pattern looks like it'll shift to a much colder and possibly whiter pattern?! Winter may get off to an early start this year around here! Stay tuned and keep checking back on the webcam to see when snow finally covers the ground.
10/30/18 - 11:02AM - After our recent cold snap and multiple light snow events, temperatures will moderate over the next week or so with highs in the 40's and 50's, but the weather will remain active with rain expected each day after Wednesday of this week. The leaves have all dropped with the exception of the oaks, which tend to hang on tough until mid-November. Hunting season in now underway.
10/18/18 - 5:28AM - SNOW!!! We had our first snow as a squall came through around 3AM this morning. It was enough to put a dusting down on all colder surfaces. Now we're just waiting for the wind to ramp up!
10/17/18 - 9:02PM - A Wind Advisory is up for tomorrow for wind gust throughout the day of over 40MPH. It will be a cold day as well with high temps remaining in the 30's, with wind chills in the teens. Some snow flurries may even be in the air from time to time, with accumulating snow likely in the western Maine mountain notches! Winter is on its way!
10/11/18 - 2:50PM - My new webcam is now installed. Check it out above! It's a 4MP HD Reolink IP camera that updates once per minute (just refresh your browser for the latest image). And its up just in time for peak foliage season here!
10/05/18 - 7:02AM - We are under a Freeze Warning for tonight as temps are expected to drop into the upper 20's to around 30F. We have already dropped to 31F a couple weeks ago, so our growing season has already ended, but any areas around that didn't see those cold temps will likely see them tonight.
10/04/18 - 7:50AM - The rainy weather continues for a welcome change as we definitely needed it! And now the fall foliage is rapidly emerging with northern Maine and the mountains now in peak conditions. We are seeing moderate color in our region, with peak color expected for us within the next week or two.
9/26/18 - 8:19AM - We picked up 1.15" of rain over the past 24 hours. It is foggy and drizzling this morning but should brighten up through the day before we have to watch for Severe T-storms this evening as a strong cold front approaches from the west!
9/25/18 - 10:24AM - The growing season has officially ended here in Leeds, ME with a low temp last night of 31.8F. We were at or below freezing for a good portion of the night. Rain is moving in today, and we should see between 1 and 2" by the end of the day tomorrow.
9/22/18 - 2:26PM - Frost Advisories and Freeze Warnings are up for our area for tonight, and likley tomorrow night as the coldes airmass of the season moves in on stiff NW winds today. We have already had a frost, but a heavier frost is likely over the next few nights with much cooler daytime highs as well. With the leaves changing colors now, it really does feel like fall on this first day of the new season.
9/19/18 - 4:01PM - The leaves are starting to change colors quickly now, and with more seasonable temps on the way into the forseeable future the colors should really start to show up over the next few weeks. We would like to see some rain however as it continues to remain very dry!
8/29/18 - 5:38PM - This heat can go away any time now. It's nearly September, which means cooler temps should be on our doorstep, so hopefully this heat and humidity we are seeing now is short lived. We are also still in need of rain as it remains very dry.
8/21/18 - 3:20PM - My new ISS with the 24 hr FARS came in earlier today. It is now installed in place of my old ISS with the standard radiation shield, and I will keep that one in storage as a back-up. I'm anxious to see the difference with this new and improved ISS! Fall foliage season is right around the corner here in Maine. Foliage page updates will begin on this site within the next week or so.


The celebration of the Joint 2021 WDA-EWDA Conference would have implied that around 400 researchers from many different points in the world would have travelled to Spain. With an estimated total CO2 emission of 1,200 tons of the last WDA-EWDA Joint Conference of Lyon (France) in 2012, it was estimated that the 2021 event would have contributed with a carbon footprint equivalent to the emissions of over 200 European citizens along a year.
The Organizing Committee of the Conference adopted a series of measures to reduce the carbon footprint of the presential Conference with the recommendations of the EWDA Sustainability Committee. The question was how reducing and mitigating the environmental effect caused by the Conference. The EWDA Sustainability Committee evaluated the contribution of EWDA conferences in terms of CO2 costs and identified that air travel is behind the 90% of the total emissions (https://ewda.org/bulletin-newsletters/). Holding a Virtual Conference will result in an almost absolute reduction of the carbon footprint of the WDA community. We Spaniards face bad situations by saying 'every cloud has a silver lining', and this time the Virtual Conference will reduce our environmental impact almost absolutely. The second measure aimed at reducing the environmental impact of the conference was to mitigate the unavoidable environmental effects caused by the Conference. The Organizing Committee set up a series of reforestation activities to which the participants of the Conference could voluntarily contribute. The EWDA Sustainability Committee estimated that the plantation of around 1,000 Mediterranean native trees will reduce the carbon cost of the Conference over a 40-year period. Three different tree planting activities were organized for the 2021 Conference in liaison with local authorities, environmental associations and locals. Maintaining this action in 2021 may help mitigate the impact of past WDA face-to-face conferences. The Organizing Committee is looking for the most appropriate ways to contribute to this cause and achieve the goal of replanting more than 1,000 trees in Cuenca.
