The hot and humid conditions begin on Wednesday, and continue through at least Friday across northern New England. The heat peaks on Thursday, with only a gradual cool down expected into the weekend. Nighttime lows in the 70s offer little relief, and result in accumulated heat stress. Starting late today through the end of the week the ingredients will be there for thunderstorms, some of which could be strong to severe. SPC has a Marginal Risk for severe storms for at least a portion of our area late today through Thursday. |
