 A burst of mild air will build across the northeastern United States after Christmas Day.

The post-Christmas mild spell will be most noticeable across the mid-Atlantic.
“Very mild and balmy springlike weather could reach the Middle Atlantic states late Monday or Tuesday,” AccuWeather Chief Meteorologist Elliot Abrams said.
The mild conditions will first reach the Ohio Valley on Monday. Temperatures will reach the 50s and lower 60s in places like Baltimore, Philadelphia, New York City and Washington, D.C., from Monday to Tuesday.

Monday night is setting up to be particularly balmy across the Northeast, with temperatures rising throughout the night.
The mild air will surge northward ahead of a Christmas Day storm over the central U.S.

The chill will be more stubborn in relinquishing its grip on New England and interior areas of the Northeast, leading to some ice as the storm arrives late on Sunday night into Monday. Rain will otherwise dampen the Northeast.
The mild spell will be short-lived to the disappointment of some.

“A quick but sharp cold air mass will cross from the Midwest to the East [later next week],” AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
The return of cold air will bring more opportunities for lake-effect snow downwind of the Great Lakes to end the year.
