Temperatures above 90 expected on Tuesday as heat wave continues across Mass.

Temperatures across Massachusetts are expected to clear 90 degrees on Tuesday, the second straight day of sweltering conditions amid a heat wave blanketing the state.

It could get as hot as 95 in parts of the Bay State, with Boston, Worcester and Springfield all expected to see temperatures at or above 93. Still, it won’t be nearly as humid on Tuesday as on other extremely hot days this summer, thanks to drier air mixing in at the surface. As a result, heat indices, or “feels like” temperatures, should remain right around the actual air temperature.

National Weather Service forecasters have not issued a Heat Advisory, indicating they do not believe heat indices will clear 95 two days in a row at any point this week.

The heat continues on Wednesday, with increasing dewpoints leading to more intense humidity. Forecasters are anticipating heat indices to reach between 95 and 100 in parts of Massachusetts, like the Merrimack and Connecticut River valleys.

Some parts of the state could see relief in the form of badly needed rainfall on Wednesday afternoon or evening. But no severe thunderstorms are expected.

Conditions remain unsettled on Thursday, with increased cloud cover and the chance for showers. Otherwise, Thursday is expected to be muggy, with highs in the mid-to-high 80s and dewpoints in the high 60s to low 70s.

High pressure builds over southern New England on Friday and Saturday, driving down temperatures and humidity. Onshore winds on Friday will lead to temperatures in the mid-to-high 70s along the coast and low-to-mid 80s along the interior.

Temperatures will be back to the mid-to-high 80s by Saturday.

But the respite for Bay Staters ends on Sunday, with heat and humidity returning. There is a chance temperatures will exceed 90 on Sunday, followed by accumulating rainfall into Monday.
