While feet of snow buries some communities in upstate New York into early Saturday, the next prospect for snow, ice, and rain for other cities and towns of the mid-Atlantic and the Northeast will be with a storm arriving Saturday night into Sunday.
This next storm is gathering in the southwestern Gulf of Mexico today. It appears that it will move northeastward, shifting offshore of the mid-Atlantic coast by Sunday afternoon or evening.
Like many storms along the East coast, a difference in track of a couple of hundred miles would mean the difference between mostly rain, slushy and slippery roads or no accumulation at all.
In the major cities along the I-95 corridor, from Washington, D.C., through Philadelphia, New York City, and Boston, the precipitation may start as a mix of snow and sleet early Sunday.
Light accumulations of a coating to an inch could occur in these I-95 cities before changing over to rain, which will fall for the majority of the time during the storm. Roads could be slippery at the onset of the storm when snow and/or sleet falls and coats the road.
Over some locations farther inland, a wintry mix could linger, rather than quickly changing to all rain.
Along the spine of the Appalachians, from North Carolina to northern New England, enough cold air may be in place at the surface for freezing rain to fall. In this zone, sidewalks and roads could become extremely slippery and dangerous.
The best chance for accumulating snow will be from the area from the northern Alleghenies in Pennsylvania through upstate New York and northern New England.
