    Areas affected...southern half of Virginia southwestward across
    North Carolina...and east to the Chesapeake/Delmarva area

    Concerning...Severe Thunderstorm Watch 393...394...

    Valid 262308Z - 270115Z

    The severe weather threat for Severe Thunderstorm Watch 393, 394
    continues.

    SUMMARY...Severe threat -- including potential for large hail and a
    few damaging gusts -- continues across WW 393 and 394, and may
    spread eastward into the Chesapeake Bay region over the next couple
    of hours, possibly requiring new watch issuance east of WW 393.

    DISCUSSION...A band of strong/locally severe thunderstorms is
    ongoing from central Virginia southwestward to western North
    Carolina -- within WW 393 and 394. The storms are occurring with a moist/unstable environment near and ahead of the weak cold front
    moving slowly eastward across the area. Enhanced
    southwesterly/westerly flow aloft on the southeast periphery of the
    mid-level cyclone is providing shear sufficient for
    organized/rotating storms, with risk expected to continue locally
    over the next several hours.

    One cluster of storms in particular -- crossing
    Hanover/Goochland/Powhatan counties in central Virginia will
    approach eastern fringes of WW 393 in the next hour to
    hour-and-a-half. We will continue to monitor areas downstream
    across southeastern Virginia/the Chesapeake region for
    possible/additional WW issuance.
