After slogging through three miserable days of heat, humidity, and frizzy hair, Greater Boston residents can finally breathe a sigh of relief.
Monday morning promises to be cooler and less humid, kicking off a week of more comfortable weather.
Cooler weather replaces the oppressive air that blanketed much of the country and had people exhausted under a sweltering midday sun, then unable to sleep in the thick night air.
“If the heat didn’t get you by day, it got [you] by night,” said National Weather Service meteorologist Kim Buttrick.
But the heat finally ended with a cold front that moved into the region Sunday night.
Overnight into Monday, temperatures were expected to drop into the mid-70s, a welcome respite from the weekend’s nighttime temperatures that were mainly lodged in the 80s. Dew points, which measure humidity, were expected to drop from around 70 to the mid-60s, Buttrick said.
On Monday, Boston is expected to be mostly cloudy, with a high of about 80 degrees, she said. Scattered showers and thunderstorms will begin moving through Southern New England in the afternoon and lasting through Tuesday afternoon, Buttrick said. Some of the storms could bring 1 to 2 inches of rain, she said.
By Tuesday, even more relief is predicted, with temperatures expected to drop to the low 70s, she said.
After the showers wrap up, probably by Tuesday afternoon, the rest of the workweek is expected to be sunny and dry, with highs about 80 degrees and lows in the mid- to upper 60s from Wednesday through Friday, according to the weather service.
That seasonable weather could last through next weekend, Buttrick said.
The past weekend’s heat led local officials to issue warnings of excessive heat across much of Southern New England, and issue heat advisories for parts of Massachusetts, Vermont, New Hampshire, and Maine.
On Sunday, Boston achieved official heat wave status at 11 a.m. when the mercury hit 90 degrees for the third straight day, according to the weather service.
The city reached a high of 98 on Sunday, several degrees short of the day’s 102-degree record, set back in 1977, Buttrick said.
With the heat index, a measure of how temperatures feel with humidity added into the mix, the city reached 100 to 105 degrees Sunday, she said.
“There was no relief from the heat,” Buttrick said.
Electrical utility Eversource had additional crews working over the weekend in case of weather-related issues, but few were reported.
Boston EMS also had extra crews, and the heat appears to have been a factor in a spike of medical calls since Friday, according to a spokeswoman. From Friday to 7 p.m. Sunday, 35 patient transports were directly attributed to heat-related illnesses, she said.
High temperatures also curbed some outdoor activities.
SoWa Open Market in the South End was closed Sunday due to the heat, organizers said in a statement posted to their website, but galleries, artist studios, shops, and its vintage market all remained open.
And organizers of the 2019 Jimmy Fund 5K cancelled Sunday’s race due to the heat, they said in a Twitter post Saturday.
Heeding warnings to try to stay cool Sunday afternoon, a few dozen people waited outside for the 1 p.m. opening of the Boston Public Library — and its air-conditioned interior.
Among them was Deborah Welton, 60, of South Boston, who tried to keep some perspective about the weather.
“The one good thing I can say is it would be worse in stagnant heat,” she said. “At least there’s a breeze.”
Walter Schoen, 34, and his mother, who was visiting from New Jersey, were inside the library, instead of on a walking tour of Boston, as they had planned.
“We would have walked down Newbury Street, but it’s not fun to do that,” said Schoen, a Cambridge resident. “So we had to figure out what else to do and we’d rather be in the air conditioning than mill around the street.”
