An arctic mass arrives in Greater Boston Friday pushing temperatures into the 30s and 20s, while creating wind chills hovering near zero.

You just set your clocks back. Now get ready to watch temperatures plummet because Boston could be on track to break its low temperature record for Nov. 11 previously set in 1901, according to the National Weather Service.

The current record low for Nov. 11 in Boston is 24 degrees, but forecasters are predicting Saturday’s temperatures could drop as low as 21 degrees, National Weather Service meteorologist Lenore Correia said.

That’s well within the range of possibility for shattering the previous record, she said.

“We have a pretty good chance of breaking it in Boston,” she said.

Further to the north, an observer for the service spotted “light snow showers” Friday morning in Rowe, just on the border of Massachusetts and Vermont, Correia said.

There’s also a small chance of snow in parts of New England early Monday morning, she said, with Northeastern Connecticut, Southern Massachusetts, and the northwest corner of Rhode Island at risk of seeing flurries.

Winds whipped across Boston Friday morning, reaching up to 45 miles per hour, Correia said.

“Good news: Clearing skies now that the front has moved through most of Southern New England,’’ forecasters tweeted. “Bad news: It’s going to get wicked cold outside.”

The warmest moments of the day arrived before dawn when temperatures in Greater Boston were in the mid-40s, according to the weather service. By 5 p.m. Friday, it will dip to around 29 degrees in Boston and drop to 18 degrees overnight.

Forecasters are urging anyone planning to be out and about Friday night to dress like it is mid-winter, not late fall. “If you plan on being outdoors tonight, be prepared for bitter cold wind chills and dress accordingly for conditions more typical of mid winter,” forecasters wrote.

The cold air will be accompanied by strong, gusting winds, especially Friday morning. A wind advisory is in effect for all of Massachusetts — except Cape Cod and the Islands — until 6 p.m.

The downward slide in temperature will ease somewhat Saturday but will still be some 15 degrees cooler than normal for mid-November in Massachusetts and might generate new low temperature records, forecasters wrote. Winds will not be so gusty.

Still, “with weakening winds, it will likely feel a bit better in comparison to Friday,’’ forecasters wrote, adding temperatures will be in the 30s and 40s.

Sunday will start out cold, but the arctic mass will move out, and by mid-afternoon, temperatures will be in the 40s, forecasters wrote.
