 Plenty of extra time, plenty of shade, and give yourself lots of liquids, too. Daytime highs on the thermometer are going to be registering up in the 80s, but with the humidity, it's going to feel like it's well into the 90s, and thus the heat advisories. Overnight lows, not much lower than 65. There will be some widely scattered showers and thundershowers, both today and this evening. There's already one batch coming across Coash County, New Hampshire right now, headed towards the northwest corner of the state.
