    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, over the Delmarva Peninsula and Virginia dry air is sweeping in from the west and should prevent a period of accumulating snow.

    The dry air will limit snowfall around Philadelphia and southern New Jersey, but wrap around snow is likely to set up in bands farther north. Portions of northeastern Pennsylvania and central New Jersey will still receive from 3 to 6 inches of snow Friday night.

    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.

    As expected warm air was an 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 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.
