Flooding, Lightning, Hail Reported Across Massachusetts

Major flooding, lightning and hail were reported across parts of Massachusetts as a storm system moved through the region on Wednesday afternoon.

The flooding was reported in communities including Boston, Boxboro, Medway, Needham, Newton, Stow, Quincy and Worcester. Downed trees and dime- and pea-sized hail were also reported in many areas of the state.

Heavy Storms Bring Flooding, Lightning and Hail

Some of the heaviest flooding was reported in Boston's Dorchester neighborhood. Portions of of Morrissey and Gallivan boulevards were closed due to flooding around 6 p.m. One person tweeted out a video of the inside of a bus in Dorchester, with water up to the seats.

Wednesday began hazy and humid, but that humidity along with the sunshine fueled up the thunderstorms from the middle of the afternoon and into the early evening.

Flash Flood Watches were issued through 8 p.m. for most of interior Massachusetts, not including the Cape and the Islands, northern Rhode Island, and northeastern Connecticut.

The heavy rainfall coincided with the evening commute, affecting drivers from Boston to Worcester and even extending into northern Rhode Island, Springfield, Massachusetts, and Hartford, Connecticut. 

Overnight, it will still be on the muggy and mild side, with temperatures into the 60s under partly cloudy skies. Any lingering showers dissipate early.

We could start off with fog again early Thursday morning, but the rest of the day brings another summery set-up with a dry and sunny start, before showers and storms pop up by the afternoon. These will not be as widespread as today’s storm threat though.

Friday brings mostly cloudy skies as the warm, humid air mass sticks around, but the weak cold front slipping in from Canada into northern New England will be clashing against the humid air mass, which will cause another round of showers and thunderstorms Friday afternoon into the evening, which could extend into early Saturday as that front traverses the area.

For the first full weekend of August, Saturday remains mostly cloudy with the potential for storms in the morning, a break in the early afternoon and then a few more by the late afternoon. Sunday will be the pick of the weekend with more comfortable conditions, highs in the 70s to low 80s and plenty of sunshine.

There’s still a chance for showers late Monday into early Tuesday of next week, but the trend remains in the low to mid 80s.
