As New York City braces for a narrow zone of heavy snow, the same storm system will spread much lighter, but disruptive, snow to most other areas in the Northeast.
The storm, an Alberta clipper, was already putting down light snow and locally heavy snow showers over the Great Lakes and Ohio Valley regions Thursday.
The Midwest will not get a great deal of snow from this, not counting lake effect. However, even a coating to an inch over the Ohio Valley will cause travel problems.
The concern is that while snow amounts in most of the mid-Atlantic will tend to be light, the snowfall rate could be briefly heavy, suddenly coating roads.
As the clipper continues to roll southeastward, commuters may face slippery travel Friday morning in a swath from Indianapolis to Cincinnati and Charleston, W.Va. all the way to Washington, D.C., Dover, Del., and Harrisburg, Philadelphia and Scranton, Pa.
Similar to the Ohio Valley, a big amount of snow is not likely to fall in southeastern Virginia, south-central Pennsylvania and the Delmarva, but coating to an inch of snow can make for very slippery surfaces.
New York City isn't the only place getting snow Thursday into Saturday. Even in the Ohio Valley and the southern mid-Atlantic, enough snow will fall to make for slippery spots.
Incidentally, up to 6 inches of snow can fall in the mountains of southwestern Pennsylvania, West Virginia, and northwestern North Carolina.
The snow will then, perhaps rather suddenly and heavily, roll from west to east into New York City during morning rush hour Friday. The midday and drive home in the New York Metro area and other locations in southern New England and southeastern New York state could be a real mess, according to Meteorologist Kristina Pydynowski.
Winter Weather Expert Rob Miller stated, "The worst morning commute Friday may be from eastern Pennsylvania into New Jersey, including the western New York suburbs, where, a burst of blinding snow may quickly coat roads and greet drivers."
The storm also has sights on New England, where it is likely to fill in sporadically during the day Friday and continue in some areas through Saturday.
Folks in New England should be prepared for slow travel and foiled plans and activities anytime Friday and Saturday.
A moderate to locally heavy snowfall is in store for central and southern New England, with nuisance amounts in the north.
