    Areas affected...WV into eastern OH...western PA/MD/VA

    Concerning...Severe Thunderstorm Watch 557...

    Valid 282012Z - 282145Z

    The severe weather threat for Severe Thunderstorm Watch 557
    continues.

    SUMMARY...Some damaging-wind threat may spread eastward into this
    evening. Downstream watch issuance is possible depending on
    short-term convective trends.

    DISCUSSION...The southern portion of a long-lived storm cluster has
    remained vigorous this afternoon across western WV, with a 54 kt
    gust recently reported at KCRW. Deep-layer shear remains weak
    downstream, but favorable thermodynamics (with MLCAPE of greater
    than 2000 J/kg and steep low-level lapse rates), along with a
    reasonably well-organized cold pool (with 40+ kt noted in the 1-3 km
    layer in the KRLX VWP immediately behind the line), will continue to
    support a damaging-wind threat into central/eastern WV and
    potentially western VA. While the typical uncertainty remains
    regarding the persistence of an organized severe threat across the
    higher terrain, downstream watch issuance is possible late this
    afternoon, depending on short-term convective trends.=20

    Farther north, convection has largely weakened, though one isolated
    cell is noted in northwest PA. Renewed convection could still
    redevelop along the gust front as it spreads across western PA, with
    some lingering damaging-wind threat potentially lasting into early
    evening.
