Don’t let the sunshine fool you — bitterly cold windchills and below-freezing temperatures greeted New England on Martin Luther King Jr. Day, following a weekend storm that brought sleet, freezing rain, and several inches of snow to the region.
Temperatures were expected to reach a high of about 7 and a low near zero on Monday, according to the National Weather Service. With Arctic air pouring into the region, windchills are expected to drop temperatures to between minus-10 and minus-25 in Greater Boston.
The windchills could cause frostbite on any exposed skin in as little as 30 minutes, the weather service said.
Worcester tied for a record low temperature for the day early in the morning, falling to minus-6. The record had been set in 1970. Worcester also saw windchills as low as minus-30, according to the National Weather Service.
Boston could still break its record of zero set back in 1888, according to meterologist Alan Dunham of the National Weather Service in Norton.
Monday also brought with it the chance of snow showers after 2 p.m., according to forecasters.
Because of the wind and icy weather, there were at least 376 delays and 197 cancellations at Logan International Airport as of 1:53 p.m.
“Wind and weather have been an issue for us, as expected,” said Massport spokeswoman Samantha Decker. “But we expect tomorrow everything to be back to normal.”
There were no service issues on the MBTA due to the cold weather, said spokesman Joe Pesaturo.
More than 200 Eversource customers in Eastern Massachusetts and about 200 National Grid customers were without power as of 1:55 p.m. Eversource’s outages were concentrated in Boston, and National Grid said the bulk of its outages were in Bristol and Essex counties.
Shelters in Boston are working overtime to bring homeless people indoors for at least one night.
“In this kind of weather, we can sometimes coax those who stay outside to come indoors,” Barbara Trevisan, a spokeswoman for Pine Street Inn, said in an e-mail.
Pine Street’s four shelters have been “open around the clock and we are urging people to stay inside,” she said.
“We staff up and do not turn away anyone in the cold, and will accommodate everyone at our shelters or transport people to other shelters if they have space,” Trevisan said.
The shelter’s staff have been “out around the clock, checking on people, bringing hot food, blankets, and warm clothing — and urging them to come inside.”
“Our goal is to ensure that no one dies in the cold,” she said.
Monday night will bring a chance of flurries before 7 p.m., but any leftover cloudiness was expected to clear. Temperatures were expected to hover around zero with windchills as low as minus-18.
Tuesday will be sunny, with temperatures climbing into the low 20s in Boston. But continued wind will make it feel like minus-14. Tuesday night’s low is expected to be around 16.
Forecasters are expecting temperatures to climb during the week, with Wednesday reaching 43. Thursday could see a high of 50 degrees.
