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

It is not just bitter cold headed to the Northeast's Interstate 95 corridor this week, but also accumulating and disruptive snowfall.

At least two snow events are in the works for the Northeast's heavily populated I-95 corridor this week with the first on tap for Monday night into Tuesday in part of New England.

A second and more potent snowstorm may follow for Thursday night and Friday.

As heavy lake-effect snow persists downwind of the Great Lakes on Monday, a bit of snow will spread east to I-95 in the afternoon from Boston to New York City to Philadelphia.

For Inauguration Day, a rain or snow shower will even reach Washington, D.C., Monday afternoon.

As AccuWeather.com Expert Senior Meteorologist Alex Sosnowski first alluded to late last week, the snow will intensify across Long Island and southern New England and spread to the Maine coast Monday night.

"A sneaky system could bring also a touch of snow to Washington, D.C. to Philadelphia Wednesday night into Thursday morning," Sosnowski said.

The brunt of the eastern New England snowstorm will shift to Atlantic Canada on Tuesday, but more snow is expected to persist across eastern New England this day.

AccuWeather.com meteorologists are expecting a total of 3 to 6 inches of snow across portions of the eastern New England coast.

The remainder of the I-95 corridor, from New York City down to Wilmington, Del., will see a coating to an inch of snow Monday afternoon and evening.

While not enough to bring communities to a standstill, that amount of snow is still capable of causing slippery spots on roadways and hazards for motorists.

In the wake of this snow event, bitterly cold air will take hold of the entire Northeast for Tuesday and Wednesday. No community--even those down to northern Virginia and most of the Delmarva--will record a high above freezing either of these days.

Highs in the single digits, on either side of zero, will be common throughout far northern New England.

The brutal cold at midweek will set the stage for the workweek to end with a snowstorm, one that could bring substantial snow to a larger corridor of the Northeast than the late Monday-Tuesday event.

More details on this second snowstorm will follow on AccuWeather.com in the upcoming days.
