Thunderstorms roll through Southeastern Mass., Cape, islands

Strong thunderstorms are rolling through areas of Southeastern Massachusets, Cape Cod, and the islands today, forecasters say.

The National Weather Service warned the storms could bring strong winds, lightning, hail, and torrential downpours. They also warned that the rain could cause send small streams over their banks, and flood roads and urban areas.

Sun and clouds were expected to mix with showers and thunderstorms across Southern New England today.

With a dewpoint around 70 degrees today (as it was Sunday) and afternoon temperatures reaching just past 80, oppressive humidity will remain, and only slowly will more tolerable conditions arrive, said National Weather Service meteorologist Eleanor Vallier-Talbot.

Humidity will decline some, but it will stay uncomfortably high through Wednesday, as will clouds and a chance of rain, Vallier-Talbot said.

Tonight there’s a 60 percent chance of showers and isolated thunderstorms throughout Massachusetts, and Tuesday night into Wednesday there’s a chance for additional precipitation, said Vallier-Talbot.

Tuesday and Wednesday will also be cooler — expect afternoon highs in the mid-70s on Tuesday and in the low 70s on Wednesday.

By Thursday, however, conditions will become drier and sunnier, even as temperatures remain below 80 degrees until Saturday.
