Humid, sweltering Sunday to give way to a cool, temperate Monday, forecasters say

The weekend’s sweltering, humid weather was expected to give way to a cool, temperate work week, forecasters said Sunday, replacing the summer-like heat that paid a springtime visit to the region.

In Worcester, a 90-degree high hit around 2 p.m. Sunday matched a record for the city, while parts of Boston’s suburbs and Western Massachusetts baked in temperatures high into the 90s, according to the National Weather Service.

The humidity on top of the heat made for a scorching weather day.

Natick hit a high of 95 degrees, but it felt like 102 with the humidity factored in, according to the weather service.


That matched the highest temperatures in the state, which were also reported in communities like Norwood and Bedford, forecasters said.

The heat index, which is what the temperature feels like to the body when humidity is combined with air temperature, hit 90 degrees or more for about a dozen communities, including Boston, the weather service reported.

Officials overseeing university commencements Sunday warned people to dress cool and drink water during the ceremonies, and Mayor Michelle Wu of Boston declared a heat emergency over the weekend.

But thunderstorms moving through Western Massachusetts Sunday evening were factors in marking the end of the hot weather, with a cool-off period coming overnight into Monday, according to Andrew Loconto, a weather service meteorologist.

After storms that hit parts of the state, including Greater Boston, showers and thunder could linger in the city Sunday night, forecasters said.

The coming week’s weather should also be significantly cooler, Loconto said.

Temperatures are expected to drop dramatically Sunday evening, with Boston going down to around 60 degrees and parts of Western Massachusetts falling into the 50s, according to the weather service.

“It should be more seasonable, [with] high pressure overhead, and it should be high and dry,” Loconto said.


A sunny Monday is predicted, with temperatures in the 70s. More sun comes on Tuesday and Wednesday, with temperatures down further into the 60s, according to the weather service. Thursday and Friday are expected to be mostly cloudy, with temperatures in the 70s.

Next weekend looks to potentially be sunny and temperate in Boston, according to the weather service, with temperatures in the 70s.

The week’s expected weather comes after forecasters thought Sunday’s summer-like heat could have matched a record for May 22 in Boston of 93 degrees.

The city fell short of that mark due to a sea breeze blowing in cold air from over the ocean until mid-afternoon Sunday, according to Loconto.

The weather service measures Boston’s temperature at Logan International Airport on the coastline and that reading was in the 60s most of the day, Loconto said.

Temperatures at Logan rose quickly in the mid-afternoon, when the cool sea breeze was replaced by wind that blew warmer air from inland into the city. Temperatures climbed to the high 80s around 5 p.m., Loconto said, before dropping in the evening hours.

Worcester matched its 90-degree record for May 22, which it had previously reached in 1911 and 1992, according to the weather service.

Sunday’s temperatures followed Saturday’s somewhat milder summer-like weather, which sent crowds to beaches seeking relief.

Crowds at Revere Beach Saturday were met with a heavy police presence and authorities arrested seven people. Five people were arrested at South Boston’s Carson Beach as well.
