    Areas affected...Parts of western PA and eastern/central OH

    Concerning...Severe Thunderstorm Watch 492...

    Valid 182247Z - 190045Z

    The severe weather threat for Severe Thunderstorm Watch 492
    continues.

    SUMMARY...The most favorable corridor for damaging wind gusts will
    extend from parts of western Pennsylvania into eastern and central
    Ohio for the next couple of hours -- within Severe Thunderstorm
    Watch 492.

    DISCUSSION...Loosely organized clusters of thunderstorms are
    tracking southeastward ahead of a cold front extending from western
    PA into eastern/central OH. The PBZ and CCX VWPs are sampling around
    45 kt of west-northwesterly 0-6 km shear oriented perpendicular to
    the gust fronts of these clusters. This favorable shear orientation
    and a narrow ENE-WSW-oriented corridor of warm/moist inflow will
    continue to support damaging wind gusts over the next couple of
    hours. Thereafter, storms will eventually move southeastward into an
    air mass that has been overturned by earlier convection
    (temperatures in the lower 70s in southwestern PA). This should
    result in a gradual decrease in storm intensity into this evening.
