Boston's seasonal snowfall record of 107.6 inches from 1995-96 will be challenged by this snowstorm.
The snowstorm will clear southern New England by Monday and will taper off to the north later in the morning. Regardless, all of New England should prepare for a slower Monday morning commute with slippery roads, airline delays and disruptions to daily activities.
The greatest amount of snow and wintry mix from the storm will focus from the I-80 corridor in Pennsylvania, northward to southern and central upstate New York as well as southern New England. Heavy snow will dip southward for a time into the Laurel Highlands of southwestern Pennsylvania, western Maryland and northern West Virginia.
Travel along I-80, I-81, I-99, New York's Southern Tier Expressway and Thruway, as well as the Massachusetts Turnpike could be difficult. The snow could fall at the rate of an inch or two per hour for a time.
Enough snow to shovel and plow will fall in the swath from Buffalo, New York, and Cleveland to Pittsburgh and Scranton, Pennsylvania; Albany, New York; Hartford, Connecticut; Worcester, Massachusetts; Rutland, Vermont; Concord, New Hampshire; Portland, Maine; and Boston.
Slick travel will also result from Virginia, northern West Virginia, southeastern Pennsylvania, Delaware, New Jersey, Long Island and the southern coast of New England due to a bit of snow at the storm's onset that will change to an icy mix. Rain will follow in the southern part of this zone.
Cities in the swath that could receive a few hours of snow or ice Sunday into Sunday night include Roanoke, Virginia, Washington, D.C., Baltimore, Philadelphia and New York City.A second storm is forecast to swing up from the Southwest during the coming week. Early indications are this second storm will track farther to the north and could be a significantly warmer precipitation event with ice and flooding concerns around Tuesday.
