This steamy Summer is not giving up without a fight. Despite a few “Fall- esque ” days, heat and humidity soars again through midweek. A handful of early morning showers in northern New York and northern Vermont will roll out, yielding to partly sunny sky. Southern counties in Vermont and New Hampshire are mostly sunny this afternoon. The temp jumps from the mid 60s to mid 70s early, into the mid to upper 80s, even nearing 90 degrees in broad valleys. Dewpoint temperatures make it into the low 70s, giving the air that soupy, humid feel, and pushing heat index values into the mid and upper 90s, even close to 100 degrees. South breeze 10 to 15 mph.
Tonight, an isolated shower or thunderstorm is possible near the International Border, and into southern Quebec, but most are dry under a partly to mostly cloudy sky. It’s warm and muggy overnight, with a low in the 70s. Wednesday, more sun, but also more heat and humidity. Tuesday and Wednesday play out similarly on the thermometer and in those heat index values. Both days feature a Heat Advisory in broad valleys. (See image above for more information).
Late Wednesday night, an end is in sight. We avoid the heat wave (three consecutive days at 90° or above) with an approaching, strong cold front. That front is preceded by showers and thunderstorms. Some overnight storms could be strong to severe and produce briefly heavy rain. Then, Thursday, clouds linger over higher terrain with a few morning showers, before dewpoints and temperatures drop and skies clear. We’re in the mid to upper 70s with beautiful sunshine late Thursday, Friday and Saturday.
Have a terrific day! Stay cool!
