Partly cloudy overnight, severe thunderstorms possible Sunday evening.
The threat of rain is over as we go through the remainder of the evening. The lone batch of thunderstorms for western Massachusetts today produced more than 3 inches of rain in the Charlemont area. All of the isolated thunderstorms across New England will die out, and skies will stay partly cloudy overnight with lows near the mid-60s.
Sunday will start off very similar to today...areas of fog in the morning, with partly sunny skies and temperatures quickly warming up. However, after noontime there will be showers and thunderstorms moving towards the region. The first batch of thunderstorms are expected to develop in the Springfield area shortly after 2 p.m., with the chance of rain continuing throughout the evening and overnight.
Some of these storms may be severe as a sharp cold front will be cutting into the hot and humid airmass we've had in place for the last few days. This front will not be clearing western Massachusetts until Monday morning, so the target area for severe weather outbreaks on Sunday night will be focused further off to our west in the Mid-Atlantic. Some leftover rain sticks around for Monday morning, and then we're looking pretty nice through the first half of the workweek.
Tonight: Partly cloudy, mild and muggy, areas of fog, low 68.
Sunday: Scattered showers and thunderstorms, heaviest in the evening, severe storms possible, high 86.
Monday: Rain ends early, mostly sunny afternoon, high 85.
Tuesday: Sunny and seasonal, high 84.
