The high pressure system currently over the region will shift south tonight before a cold front ushers in scattered showers late Friday into Saturday. Bitterly cold weather will arrive Sunday and last into early next week, according to the National Weather Service.

“It will be quiet today, with cold sunshine and another cold night,” said Charlie Foley, weather service meteorologist. “Friday will see basically the same conditions, with a little less sun.”

Today will be sunny, with a high near 47. A calm southwest wind will gust up to 6 miles per hour and won’t affect apparent temperatures. Conditions will remain dry overnight, but clouds will develop, according to the weather service. Temperatures will fall into the upper 30s.

Friday will see showers beginning early in the morning, around 10 a.m. Early morning temperatures should creep above the freezing mark, and therefore the precipitation will be mostly rain. A few snow showers could pop up in higher elevations in Western Massachusetts, according to the weather service. Skies will remain cloudy, and daytime temperatures will settle near 50. Rain will continue overnight as temperatures fall into the 30s.

Showers should diminish by around 8 a.m. Saturday, and sunny skies will return. Temperatures will crest near 45. A northwest wind could gust up to 25 miles per hour, making it feel a degree or two cooler. Skies will remain clear overnight, and temperatures will fall into the upper 20s, according to the weather service.

“The intrusion of the cold air will begin Saturday but get really cold on Sunday,” Foley said.

“You are really going to feel the wind chill Sunday at the football game.”

Sunday will see frigid temperatures, with the high around 33. Winds will pick up overnight, and temperatures will fall to around 20, making for uncomfortable conditions for Patriots fans at Gillette Stadium for the game against the Denver Broncos.

The chilly weather will continue into early next week, with the possibility of some rain and snow near turkey day.

“The cold will continue into early next week,” Foley said. “There is also the potential for some kind of coastal storm around the Thanksgiving travel period.”
