Boston, Massachusetts – Thunderstorms are expected to strike the Boston metro area by mid-afternoon Wednesday, possibly snarling traffic along I-93, Route 1, and I-90 just in time for the evening commute.
According to the National Weather Service, a band of heavy rain and isolated thunderstorms will move in after 3 p.m. Wednesday, with the strongest storms likely between 3 and 8 p.m. Temperatures will climb to around 83°F, pushing humidity levels up and creating conditions ripe for flash downpours. Winds could gust between 10 to 20 mph.
Boston residents should avoid unnecessary travel after 2 p.m. and secure outdoor items. The storms are not expected to be severe but may produce brief localized flooding and reduce visibility quickly.
Wednesday night clears out with lows around 67°F and mostly calm conditions. Thursday and Friday bring a return to classic New England summer: sunny skies, low humidity, and highs in the mid-80s.
By Friday night, clouds return with a 30% chance of overnight showers. The weekend starts mild with Saturday highs near 79°F and a slight chance of rain. Sunday could bring scattered afternoon showers and a high near 86°F, so keep umbrellas handy.
