This week is forecast to be hot and humid through Thursday, with temperatures in the upper 80s and low 90s, and dew points predicted in the low 70s for a couple days. And there’s a chance of showers or thunderstorms each day through Thursday, according to local forecasters.

On Monday, much of New England is under a “severe thunderstorm watch” until 8 p.m., according to the National Weather Service.

Monday was the first day in August to reach 90 degrees in Boston, and it was the 13th time for the year, Sarah Wroblewski, a meteorologist with WBZ, said.

After the heat through Thursday, the last day of the work week is predicted to be sunny with a high of 77 degrees, the service said.

“A much warmer than average week ahead…although the thing that sticks out to me on this graphic is that the average high is now below 80 (79) in Boston,” Terry Eliasen, a meteorologist with WBZ, said.

The service predicts Wednesday to have a chance of thunderstorms and showers with the chance of precipitation at 50 percent.

“Wednesday looks like a day of thunderstorms,” Mike Wankum, a meteorologist with WCVB, said.

Wroblewski noted that “much cooler, refreshing air returns by the end of the week.”

Early predictions for the weekend from the service indicate that both days will be sunny with highs in the mid-70s.
