The heavy snow in the core of the Mid-Atlantic remains on track, given the newest model data and latest trends. Two notable changes were made to the northern and southern fringes of the snow accumulation. General timing remains the same, with snow expected to start in the D.C. area between 3-6 p.m. Friday.
The northeastern edge of the snow accumulation was cut back as confidence increases in the storm track, leaving lower snow amounts across northeastern Pennsylvania into northern New Jersey. On the southern edge, western North Carolina into western Virginia and West Virginia saw snow increases due to better confidence in the QPF forecast and better temperature profiles. Further east, more warm air wrapping into the eastern side of the system made for lower snow forecasts across northeastern North Carolina, southeastern Virginia, and along the immediate Atlantic Coast.
Ice will also be an issue in the Southeast and in southwestern Virginia. Currently, areas in northern South Carolina and central North Carolina are forecast to receive 0.25-0.75″ of ice, according to the NWS.
At the moment, the NWS also has Blizzard Watches posted from the greater D.C. region up through Philadelphia and into NYC and Long Island.
I will be posting a final forecast update this evening.
