Play video Weather across the Northeast is detailed in the above AccuWeather.com video.

Monday's mild weather in Philadelphia is not a sign of things to come with the return of snow and frigid air on the horizon.

Monday is shaping up to be a breezy and milder day in Philadelphia with temperatures set to soar into the upper 40s.

However, the polar vortex is sinking southward and will cause noticeably colder air to sweep in for Monday night and Tuesday. About 20 degrees will separate Monday's high from Tuesday's.

In fact, Tuesday's high will likely be recorded in the predawn hours than the afternoon.

Residents will not just be bundling up on Tuesday, but will also be clearing snow. An Alberta Clipper at the leading edge of the arctic blast will spread a band of snow from the Ohio Valley to the mid-Atlantic on Tuesday.

While heavier amounts will fall in the mountains of Virginia and West Virginia, amounts on the order of 1 to 3 inches are expected in Philadelphia.

AccuWeather.com meteorologists will continue to monitor the storm for the possibility of the heavier snow band developing closer to the city.

This snow is still enough to turn sidewalks and roads slippery, especially toward and after dark. Airline passengers should prepare for possible flight delays.

Biting winds ushering in the colder air will drop AccuWeather.com RealFeel® temperatures into the single digits on Tuesday.

In the wake of the snow, temperatures will plummet into the teens Tuesday night and remain there through Wednesday night. Brisk winds will continue to create dangerously colder RealFeel® temperatures.

Yet another Alberta Clipper will return the chance for a little snow on Thursday before fresh frigid air arrives later in the week.
