Hot day and thunderstorms to be followed by a cool night

Temperatures will reach the upper 80s to mid-90s today under partly sunny skies before a cold front crosses Southern New England, triggering isolated thunderstorms this afternoon across Eastern Massachusetts, forecasters say.

“The big change related to the cold front is drier and more comfortable air is seeping into the region,” said Charlie Foley, a National Weather Service meteorologist. “If you have an air conditioner, you won’t need to turn it on tonight.”

Humidity could return Thursday, along with a higher chance of showers and thunderstorms in Eastern Massachusetts. High temperatures are expected to reach 75, with clouds likely throughout the day.

The chance of precipitation will shoot up again Sunday, with rain likely to continue into the early week.
