    Mesoscale Discussion 1333

    Areas affected...central Virginia into the Delmarva

    Concerning...Severe potential...Watch unlikely=20

    Valid 261937Z - 262130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...The potential for locally damaging wind gusts is expected
    to increase across the discussion area this afternoon into early
    evening. The areal coverage and magnitude of the threat are expected
    to remain too limited for a watch consideration.

    DISCUSSION...Recent radar trends indicate gradually strengthening
    storms along the Blue Ridge Mountains in northern VA with additional
    storms noted in southeast WV. East of the high terrain, a relatively
    warm and moist air mass is present with steep low-level lapse rates
    and MLCAPE of around 1000 J/kg indicated in latest objective
    analyses. The presence of a westerly, deep-layer wind field should
    support the eastward movement of storms across the discussion area
    with the absence of appreciable forcing for ascent potentially
    limiting overall storm coverage.

    The KRLX and KLWX VWPs indicate 30-35 kt winds above 5 km, which are
    boosting vertical shear generally along and north of that latitude.
    That modest shear enhancement may contribute to some briefly
    organized storms capable of locally damaging wind gusts. Relatively
    warm mid-level temperatures and resultant poor lapse rates should
    limit large hail potential.

    Given the expected isolated nature of the threat, a watch is not
    anticipated.
