As a large storm rolls out of the Plains and Midwest, a swath of snow, ice and travel disruptions will extend into the Northeast starting on Sunday.
The wintry precipitation will focus along a boundary between mild air to the south and cold air to the north.
A fairly long-duration winter storm will affect the Interstate-80/I-90 corridor of the Midwest during Saturday night and Sunday.
The worst of the storm will hit the Northeast from Sunday night into Monday.
The Monday morning commute could be a real mess as millions of people head back to work or school following the weekend. People should expect another round of slippery roads and airline delays with possible cancellations and disruptions to daily activities.
The greatest amount of snow and wintry mix will focus from the I-80 corridor northward in the mid-Atlantic and across much of New England.
Enough snow to shovel and plow is possible in the swath from Cleveland and Buffalo, New York, to Scranton, Pennsylvania; Albany, New York; Hartford, Connecticut; Worcester, Massachusetts; Rutland, Vermont; Concord, New Hampshire; Portland, Maine; and Boston.
A few pockets of ice or a wintry mix will occur south of the snow area from part of northern Virginia, northern Maryland and northern West Virginia to southern Pennsylvania, northern Delaware, New Jersey, Long Island and the southern coast of New England. Otherwise, in this swath, much of the storm is likely to bring rain.
Cities in the swath that could receive a few hours of ice or a wintry mix Sunday night into Monday include Pittsburgh, Washington, D.C., Baltimore, Philadelphia, New York City and Providence, Rhode Island.
