As two storms converge over New England, rain and a wintry mix will change to snow Friday into Friday night creating slippery roads over a large part of Pennsylvania and New Jersey.
A band of mixed precipitation is heading eastward from the Ohio Valley and will end as a burst of snow and slippery conditions from the mountains of the Virginias, western Maryland to much of Pennsylvania.
Across upstate New York, two areas of snow are converging into Friday night and will result in widespread slippery travel.
The storm will bring enough snow to shovel and plow across northern Pennsylvania, part of eastern Pennsylvania, central and northern New Jersey and much of New York state.
Farther south, periods of drenching rain are in store from the Jersey Cape through the Delmarva Peninsula. A second period of rain will sweep eastward across Virginia and Maryland Friday, which can end as a brief period of snow or mixed precipitation in some of the northern and western Washington, D.C., and Baltimore suburbs later in the day.
Depending on the speed of the merging of the two storms, a few inches of snow could fall on parts of southern New Jersey. Regardless of how quickly the two storms come together, close to a half a foot of snow will fall over parts of northeastern Pennsylvania and northern New Jersey.
A narrow zone of snow fell early Friday morning over western Virginia, in the Roanoke area. This has penciled out approaching the northern and western suburbs of Washington, D.C., and Baltimore.
Without a blocking area of high pressure over the Greenland, this storm will keep moving along.
The heaviest snow is likely to fall from near New York City on east into New England and Long Island Friday night.
Warm air will be another issue in the New York City metropolitan area and Long Island causing part of the storm to be rain or a wintry mix and some of the snow to melt as it falls on roads during the first part of the storm Friday. However, intense snowfall rates Friday night will overcome this.
The southern part of the storm has drenched the South with beneficial rain, but it has also caused urban flooding problems and locally strong thunderstorms Wednesday night into Friday. That area of rain was affecting the coastal mid-Atlantic during the midday hours Friday and will transform, with the aid of the system moving in from the Midwest to a major blizzard over New England Friday night.
A brief shot of blustery, seasonably cold conditions is in store for Saturday in the wake of the storm. Temperatures will moderate Sunday, setting the stage for the next storm system Monday to bring mostly rain to the region with a wintry mix over northern upstate New York and northern New England.
The atmosphere is in the process of building a pipeline of storms for the eastern part of the nation during the balance of February. Most will bring rain to the mid-Atlantic coast, but some could bring snow. Details will follow as the time draws nearer.
