The heat wave has ended for New England, with 90s not expected Monday. That said, while the deep heat has been forced south and the humidity has been cut back, it’s still humid enough that incoming disturbances aloft, moving west to east across New England, will trigger showers, downpours and thunderstorms.
The unsettled weather will come in fits and starts, at first, then expand and become more consistent as afternoon turns to evening. Feeding off plenty of humid air aloft, downpours will drop quick, hearty rainfall that may result in localized flooding and ponding of water Monday evening into Monday night.
In southern New England, particularly near the South Coast, we’ll also be on guard for embedded strong wind gusts that may cause localized damage.
Expect periods of rain and embedded thunder to continue off and on through the overnight into Tuesday morning, slowly settling southeast as the day wears on, but still producing showers for much of southern New England through at least midday, holding temperatures to the lower 70s at even their warmest point.
Northern New England is likely to stay dry after an early shower exits Maine, and that dry and comfortable air will take over for all of New England for a pleasant and lovely day Wednesday, lasting into the start of the weekend with slowly rising temperatures that eventually will near 90 this weekend, first inland on Saturday, then even to the coast Sunday as humidity increases and a chance of thunder builds.
The heat and humidity is expected to stick around through the first half of next week in our exclusive First Alert 10-day forecast.
