Forecasters canceled a flash flood watch and severe thunderstorm watch for portions of southern New England, but they warned of the chance of continued showers and scattered thunderstorms into Thursday.

Potential rainfall rates could be 1 to 2 inches per hour. Forecasters also warned of localized flooding.

Thunderstorms swept through Greater Boston around 5:30 p.m. Wednesday.

The storms also included lightning.

Earlier Wednesday afternoon, forecasters had warned of a possible tornado in Western Massachusetts. A tornado warning was issued for Central Berkshire County after forecasters spotted rotation on their radar, but the warning expired at 4 p.m.

It will be humid overnight Wednesday with lows hovering around 70.


Remnants of Hurricane Barry were moving across southern New England, bringing more showers and scattered thunderstorms that will continue through most of Thursday, forecasters said.

Thursday will be much cooler, with temperatures in the lower 70s during the day, and falling to the 60s at night. But don’t get used to that: This weekend, as they say around these parts, will be a “scorcha.”

Expect hot and humid weather Friday, with plenty of sunshine and highs reaching the upper 80s.

And then Saturday will be even hotter. The day will be sunny, and there’s a chance of record-breaking heat, as temperatures in the Boston area soar to the upper 90s. (In case you’re wondering, the record high for July 20 was 99 degrees, back in 1991).

Saturday night will be partly cloudy and hot, with lows only dropping to around 79, and the sunshine — and scorching heat — will return Sunday, with temperatures reaching the lower 90s.

“Much of the interior could have a heat index around 95F to 100F Friday and Sunday, and a heat index of 100F up to 110F on Saturday,” forecasters wrote.
