8/22 storm threat

Clouds linger across western Mass this evening and tonight. Temperatures remain mild, but they only dip into the upper 60s tonight as skies turn overcast and rain moves in with an approaching warm front.

Wednesday is a First Warning Weather Day!

Showers and an embedded thunderstorm are expected from 3-4 am through mid-morning as this front comes through. The severe weather threat for the morning is quite low, but with the warm front, higher dew points and stronger winds aloft, a few very isolated strong to severe storms are possible. An isolated tornado is always a small concern in this setup.

We should see a break in showers mid-morning and if the sun can come out, then some stronger thunderstorms would be possible with a passing cold front in the early afternoon. It's possible that clouds linger and our atmosphere doesn't destabilize enough to give us much for thunderstorms with the passing cold front. Dew points will climb into the 70s ahead of the front, so at least some scattered downpours should occur.

Once we are behind the cold front Wednesday evening, our weather will improve quickly. Skies clear out and drier air gradually works in Wednesday night. By Thursday, dew points will be in the 40s-giving us a fall-like feel outside! Don't get too used to it though. After another dry, cool start Friday, temperatures return to the lower 80s in the afternoon under a sunny sky. Temps should reach low 80s over the weekend as well.

Our cool nights at the end of the week get a bit milder over the weekend with lows back to around 60. A ridge of high pressure will build into the Southeast over the weekend, which will help to bring in some warmer, more humid air starting Sunday and especially for early next week. We may see highs get into the 90s by Monday and Tuesday.
