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.
