Get Ready Boston: One of the wettest The summer recorded since 1872 is expected to bring more rain on Friday.

Individual storms are expected to be violent, with thunder and lightning posing the greatest threat. The almost all-day flooding could also bring damaging winds, pea-sized hail and even a smaller but still existent threat of flash floods and tornadoes.

Here’s what to expect and when to expect the blustery weather this Friday National Weather Service.

When will it rain on Friday?

NWS Boston meteorologist Matthew Belk said a warm front will move north through New England around midnight, and storms will follow shortly after.

Rainy weather and thunderstorms will continue through Friday afternoon, bringing a possible three-quarters to an inch of precipitation.

As early as 2 p.m., a cold front will move in from the west, which will ensure drier, cooler weather and put an end to the worst storms. But Boston, and particularly southeastern Massachusetts, could still experience a cluster of rainstorms into the evening.

More threats in the forecast

The main concerns for tomorrow According to Belk, there is a risk of thunderstorms and lightning, especially earlier in the day.

“If you’re outside and you hear thunder, you’re in range,” Belk said. “At that point, it’s probably time to go inside. That is the best advice we can give.”

Belk said noxious winds are the second biggest threat. The NWS forecast indicates that wind gusts of up to 21 miles per hour can occur on Friday.

Hail measuring about half an inch, and as much as an inch in areas with the fiercest storms, is also a concern. Although the risk is lower, flash flooding is still a possibility and the severity depends on how fast a storm is moving across an area – although Belk gave good news that the torrential rains are expected to spread quickly across the region.

Tornadoes are similar to one lower risk.

More about the weather in Boston

When the warm front moves in, residents can expect hot and muggy weather with highs of 81 degrees. But once that cold front dries up the blustery weather, Friday night will see lows of 60 degrees and drier, cooler weather will continue into Saturday.

The forecast is for a weekend of sunnier skies before a return of rain is possible on Monday evening.
