    Areas affected...Northern Virginia...Eastern West
    Virginia...Southern Pennsylvania...Maryland...Delaware...and New
    Jersey into Long Island.

    Concerning...Winter mixed precipitation=20

    Valid 252002Z - 260000Z

    SUMMARY...Sleet continues this afternoon. A brief period of freezing
    rain is possible by early evening.

    DISCUSSION...Moderate sleet continues from northern Virginia/eastern
    West Virginia to Long Island. As expected, the sleet/snow line has
    advanced north with sleet now reported in New York City and Long
    Island. From this area and to the southwest, an expansive area of
    sleet continues.

    While some guidance precipitation algorithms (such as the HRRR)
    indicate there may be some freezing rain and ice accretion later
    this afternoon, confidence in additional icing is low. Forecast
    soundings where the freezing rain is depicted still show boundary
    layer temperatures of -10C. Despite it being relatively shallow, it
    may remain sufficient for refreezing to sleet. By the time the
    profiles look more supportive for freezing rain, precipitation is
    coming to an end. Therefore, some pockets of additional icing of 0.1
    to 0.2" are possible, but the majority of the precipitation this
    afternoon and into the early evening will likely fall as sleet.=20

    In the wake of the primary precipitation shield, forecast soundings
    show residual low-level moisture which could result in some freezing
    drizzle later this evening.
