Boston, MA – High heat and humidity are gripping Massachusetts today, with inland temperatures soaring into the 90s and a risk of isolated afternoon thunderstorms that could impact evening travel and outdoor plans.
According to the National Weather Service in Boston/Norton, widespread highs of 90–95°F are expected away from the immediate coastline, where cooler sea breezes will keep temperatures in the upper 70s to low 80s. The hottest zones include Springfield (93°F), Worcester (92°F), and Fitchburg (91°F), with scattered storms most likely between 2 and 6 p.m.
While most areas will remain dry, isolated cells could bring brief downpours, lightning, and gusty winds—particularly around central and southeastern Massachusetts. Springfield and Providence are under a limited storm risk zone this afternoon. Commuters along I-90, I-91, and I-95 should stay weather-aware during the afternoon peak.
Residents are urged to stay hydrated, limit strenuous activity during peak heat, and keep an eye on skies if outdoors. This heatwave marks one of the season’s first widespread 90-degree events, coming on the heels of cooler early June days.
Storm chances fade tonight, but temperatures remain warm and muggy. Additional heat and possible storms are expected later this week.
