Thunderstorms could reach I-495 by evening commute

The sun will make frequent appearances this week, even as the threat of showers and thunderstorms persists, the National Weather Service said.

Today will likely be mostly sunny and warm, with high temperatures in the mid-80s. Showers and possibly thunderstorms will be moving in later in the day, hitting “Western Massachusetts by this afternoon, and possibly reaching over I-495 by the evening commute,” said Bill Simpson, a National Weather Service meteorologist. The precipitation will be likely to continue overnight.

Wednesday will see a chance of showers and storms throughout the day, the Weather Service said.

“With the nature of showers, the vast majority of the day will be dry,” Simpson said, “but it if does rain, it’ll rain pretty hard. I guess the catch phrase everyone has been using is ‘pop-up showers.’” These showers and storms will probably move out by 10 p.m. Wednesday will be a little cooler than today, with high temperatures in the upper 70s.

By Thursday, showers and storms are still possible, though less so. Simpson said “widely scattered showers” are possible Thursday afternoon, meaning they are even less likely than “scattered” showers. These should move out of the region by Thursday night.

By Friday, the weather pattern will change, Simpson said, bringing sunshine and temperatures in the high 70s.

“Nice timing for the weekend,” Simpson said.
