Temperatures could clear 90 on Monday as heat, humidity return to Mass.

Temperatures across Massachusetts could cross 90 degrees on Monday as heat and humidity return to the Bay State.

The surging temperatures on Monday are part of a broader warming trend in the state, which is expected to persist through Wednesday. But National Weather Service forecasters say they don’t expect to issue a heat advisory as the heat won’t be as oppressive as earlier this summer.

Still, there is a chance heat indices, or “feels like” temperatures, approach the criteria for an advisory by reaching between 95 and 100 for two or more hours. It will be warmest in usual “hot spots” across Massachusetts like the Merrimack Valley and the suburbs southwest of Boston.

The heat will continue on Tuesday, with temperatures again climbing into the 90s. But dewpoints are expected to fall slightly thanks to drier air moving in, meaning there will be slightly less moisture in the air and thus less humidity.

With lower humidity on Tuesday, heat indices are not expected to reach the criteria for a heat advisory.

Wednesday is expected to be the peak of the heat and humidity this week, with dewpoints in the low 70s and heat indices climbing to the mid to high 90s in parts of the interior. A few severe storms can’t be ruled out on Wednesday due to unstable conditions, forecasters said.

A cold front will break the heat on Thursday, bringing with it the possibility for severe storms. Still, forecasters think it is unlikely Massachusetts will be hit hard.

The front moves offshore early Friday, leading to drier and cooler conditions through Saturday. However, the high-pressure system that caused the heat is likely to reassert itself later in the weekend, leading to the heat and humidity returning Sunday and into next week.
