    Areas affected...parts of the Mid-Atlantic into the New York Metro
    Area.

    Concerning...Winter mixed precipitation=20

    Valid 031058Z - 031600Z

    SUMMARY...An area of freezing rain, with some snow on the northern
    extent, continues this morning.

    DISCUSSION...A precipitation shield is expanding across the
    Mid-Atlantic this morning as isentropic ascent increases. Area VWPs
    at LWX, CCX, and PBZ have sampled increasing 1-2 km flow over the
    past few hours to near 35 to 40 knots. Even stronger flow (~45
    knots) is evident on the RLX VWP. This stronger flow will spread
    northeastward through the morning and will result in greater
    precipitation rates. Mostly freezing rain, with some snow is being
    observed this morning across the region. Across northern Virginia
    and Maryland, where temperatures are currently near 32F, expect a
    transition to mostly rain relatively soon as southerly flow
    strengthens this morning. Farther north across Pennsylvania, expect
    the freezing rain to persist into the morning where wet-bulb
    temperatures are in the 20s. Across eastern Pennsylvania into
    northern New Jersey and southern New York, temperatures will stay
    well below freezing through the morning. Forecast soundings indicate precipitation may be primarily snow initially with a few hour
    transition to freezing rain by late morning.
