The second part of a double-barreled storm is tracking farther south than the first and will continue to spread accumulating snow from northern Ohio to the Delmarva Peninsula and southern New Jersey.

The heaviest snow tonight will fall in the mountains of south-central Pennsylvania, western Maryland and northern West Virginia.

Enough snow will fall in Wheeling and Morgantown, W.Va.; Pittsburgh, Altoona, Johnstown, Harrisburg, Lancaster, York, Reading and Philadelphia, Pa.; Cumberland, Frederick and Baltimore, Md.; Vineland, Atlantic City and Cape May, N.J.; Wilmington and Dover, Del.; Winchester, Va.; and Washington, D.C., to make roads slippery for the morning drive Tuesday.

Travel and school delays are to be expected, and there could even be some school cancellations.

The snow will start off rather wet but will become drier as temperatures fall a bit. This will cause the snow to cling to many elevated objects, weighing down trees and power lines. Roads could get icy.

The first of the two storms spread a swath of accumulating snow from the Upper Midwest to part of the mid-Atlantic and southern New England, as discussed by Meteorologist Megan Evans.

A cold press following the first storm is driving the second storm to the south. In most cases, if you got more than a couple of inches of snow from the first storm, you will not get more than that from the second storm. There will be a few exceptions.

There will be sharp northern edge to the snow with the first storm. No accumulating snow is expected in Boston, Hartford, New York City, Binghamton, Buffalo and Detroit, where dry air will rob the storm of moisture.

Farther south, mostly rain is forecast in Richmond, Charlottesville, Roanoke and Charleston, W.Va., with perhaps a brief wintry mix at the end with cold air arriving at the last minute.

People on the Eastern Shore in Maryland and southeastern Delaware may get a slippery coating to an inch or two as rain mixes with then changes to sleet then snow.

Once this storm passes off the Atlantic coast Tuesday, attention will turn to the next potential trouble-making storm for the eastern part of the nation.

A stronger storm threatens to bring everything from flooding rain to heavy snow and perhaps severe thunderstorms Thursday night and Friday. The range of tracks with the late-week storm range from off the mid-Atlantic coast to up over the eastern Great Lakes.

So it appears the warmth and tranquil conditions of last week were "gone with the wind" over the weekend.

The upcoming pattern looks to be quite stormy for at least the next couple of weeks.
