Another warmup will take shape over the northeastern United States at midweek.
Clear skies on Monday night will yield temperatures below freezing across much of the interior Northeast and portions of the mid-Atlantic. Those heading out for Halloween festivities will want to dress warmly.
"Following a chilly Monday night into Tuesday morning, the return of warmer air will be on the horizon," AccuWeather Meteorologist Matt Rinde said.
Temperatures from Washington, D.C., to Boston early in the week will hover between 15 and 25 degrees Fahrenheit lower than over the weekend.
Despite the cooler weather, high pressure will bring afternoon sunshine across the region through Tuesday.
Highs through Tuesday will range from the 40s and 50s from upstate New York into New England, to the 50s and lower 60s across the mid-Atlantic.

This cool air mass will be short-lived as another warmup will arrive by the middle of the week.
"A considerably milder air mass will reach the East by Wednesday," Rinde said.
The warmer air will stretch across locations west of the Appalachians by Tuesday and reach the rest of the mid-Atlantic and Northeast on Wednesday. Highs at the peak of the warmth will be similar to those from the weekend.
Highs will again reach into the 70s across much of the mid-Atlantic and into the 60s across southern New York and New England. Highs will hit in the 50s across northern New England.
However, the warm spell will be brief.
"An approaching storm will lead to the development of showers and thunderstorms during Thursday afternoon from northern Virginia into southern New England, some of which could contain damaging winds," Rinde said.
Those along the Interstate-95 corridor from Boston to New York City and Washington, D.C., will want to keep an eye to the sky for rapidly changing weather conditions.
Additional waves of colder air will make brief appearances to the Northeast for much of November and into December with brief warmups in-between.
