Areas in dark grean were under a flash flood watch around 5:45.

With flashes, booms, and buckets of wind-driven rain, thunderstorms are sweeping across Massachusetts today.

Forecasters at one point issued a tornado warning and severe thunderstorms warnings as the storms rolled through.

The storms knocked down power lines and trees in a number of communities and flooded roads, according to reports fielded by the National Weather Service.

The service issued a flash flood watch for the entire region — except Cape Cod and the surrounding islands — through Wednesday afternoon in anticipation of the storms.

Forecasters warned that isolated severe storms could dump between 2 and 4 inches on the region, but higher amounts are possible.

At 5:30 p.m., a record rainfall of 2.16 inches was recorded at Worcester, breaking the old record of 1.71 for the day set in 1978.

“You can tell when you're outside, the atmosphere is really juicy,” said Kim Buttrick, a National Weather Service meteorologist. “Dew points are ... unusually high.”

The chance for storms decreases after 1 a.m. Wednesday, but rain is likely to continue overnight. Temperatures may fall to the low 70s.

Wednesday will likely be damp, with a chance of showers and thunderstorms persisting throughout the day, though it will be cooler, with temperatures hovering in the mid-70s. Showers and storms are likely in the evening before midnight; temperatures may fall to the mid-60s.

By Thursday, things should be clearing up.

“Right now it’s looking like the cold front will exit east of Cape Cod Thursday morning,” Buttrick said. “Behind it will be lower dew points, so less humid conditions, and it is expected to be dry with seasonal temperatures Thursday, Friday, and perhaps into the weekend.”

Current forecasts call for another cool, dry weekend, with plenty of sunshine and consistent high temperatures in the low 80s.
