 Rocky Mountain News Network, I'm Teresa Taylor. If you enjoyed the cooler temps across eastern Colorado on Sunday, you'll have one more day today as most locations along the Front Range will climb into the lower 80s. Temps for the eastern plains will return to the 90s starting Tuesday as a ridge of high pressure slides our way. That same ridge has been responsible for a prolonged heat wave on the west coast where most areas are under heat advisories and warnings.
