    Areas affected...portions of northeast Virginia

    Concerning...Severe Thunderstorm Watch 234...236...

    Valid 202314Z - 202345Z

    The severe weather threat for Severe Thunderstorm Watch 234, 236
    continues.

    SUMMARY...A damaging gust or episode of hail may occur in the next
    1-2 hours.

    DISCUSSION...A cluster of storms continues to track northeast toward
    a localized a pristine airmass that has yet to be overturned by
    convection (e.g. the Grant County Airport ASOS showing 87 F surface temperatures). As such, storm cores in the area may remain strong
    enough over the next 1-2 hours to produce a damaging gust or
    instance of hail as they approach this reservoir of potentially
    unstable air. Thereafter, the severe threat should continue to
    diminish with time.
