Did you enjoy Boston’s picturesque white Christmas? Now it’s time to bundle up even more as bitter cold moves into the area.

 

The National Weather Service has issued wind chill warnings for central and eastern parts of Massachusetts, as well as Connecticut, as wind will dip temperatures dangerously low Wednesday night and through to Thursday morning.

 

The weather service is advising people to keep their skin covered when outside to protect against frostbite. Forecasters are predicting wind chills of -13 degrees in Boston Thursday morning and say that more wind chill advisories may be needed for the coming weekend, as well.

 

Daytime temperatures in New England are not expected to rise out of the 20s all week, forecasters said. In Boston, temperatures could reach a high of 18 degrees on Wednesday and 11 degrees on Thursday, but with strong wind chills, things will feel even colder.

 

“Wind chill is based on the rate of heat loss from exposed skin caused by wind and cold,” the National Weather Service explained. “As the wind increases, it draws heat from the body, driving down skin temp and eventually the internal body temp. Therefore, the wind makes it feel much colder.”

Wednesday night and Thursday, wind chill figures could be as low as -13 degrees. On Thursday, winds will be around 7 to 9 mph, with gusts as high as 21 mph.

For Friday, forecasters are predicting a high near 15 degrees with winds around 5 to 7 mph. By Friday night, the lowest temperature is expected to be around 5 degrees.

This weekend may see some snow, the weather service said. The current forecast puts the chance of flurries at around 30 percent.

For next week, “Sunday through Tuesday, … other than possibly some ocean effect snow showers over the outer Cape during Sunday morning, it looks to remain cold and dry with a reinforcing shot of arctic air,” forecasters said.

Boston Emergency Medical Services has also warned residents not to stay outside too long and to dress appropriately for the low temperatures. Mayor Marty Walsh has issued tips for Bostonians in advance of the bitter cold.

With wind chill, frostbite can occur in 30 minutes, experts say. Walsh is encouraging residents to check on neighbors, be mindful of homeless individuals who may need help and to be cautious when using space heaters.

The Boston Centers for Youth & Families community centers are open to those who need a warm place to visit during the day — locations and hours are available here. Boston’s resident services hotline 311 is open for questions, and more tips can be found at boston.gov/cold.

"We want to make make sure each and every Boston resident will be safe and warm when bitterly cold weather arrives this week," Walsh said in a statement. "In times like these, it's vital for residents to look out for one another, and I encourage all Bostonians to reach out to the city if they or their neighbors need help this winter season. City workers will be constantly vigilant to ensure the safety of all."
