It probably won’t be a white Christmas in much of Massachusetts, but it sure will be a chilly one — with temperatures in the 20s and a northwest wind gusting to around 13 miles per hour.
Today will begin mostly sunny, but clouds will increase through the afternoon. Temperatures will crest in the low 30s, and a northwest wind could gust up to 10 miles per hour, adding a bite to the cold.
“The normal temperature today in Boston is 39, so we will be slightly colder than normal,” said William Babcock, weather service meteorologist. “It will be mostly dry, though another couple hours of rain are possible along Cape Cod.”
More clouds will enter the region overnight and temperatures will fall into the mid-20s, according to the weather service. Northwest wind gusts will increase overnight to around 20 miles per hour, so Santa might want to pack an extra layer or two in his sled.
“Overnight the wind chills will be down near zero, driven by the wind gusts,” Babcock said.
Christmas Day will be sunny. There’s a slight chance of snow, but any accumulation will be light. Clouds will enter New England overnight and temperatures will remain in the low 20s.
A mixture of rain and snow showers is possible Thursday as temperatures warm up, but they should taper off by around 4 p.m. Snow showers are more likely in the morning, transitioning to rain in the early afternoon. Skies will be mostly cloudy, with a daytime high near 40. Clouds will diminish overnight and temperatures will settle in the mid-20s, according to the weather service.
Friday will be mostly sunny, with a high near 36. Clouds will enter the state overnight and temperatures will fall into the low 20s, according to the weather service.
“As it appears now, there will be some more seasonable temperatures and mostly sunny skies over the weekend,” Babcock said.
The official government definition of a white Christmas is when there is at least 1 inch of snow on the ground on Dec. 25, no matter when the snow fell. According to a National Weather Service snow depth map, southern sections of Massachusetts will not even have an inch of snow on the ground on Wednesday.
