    Areas affected...Ohio/western and central Pennsylvania/West
    Virginia/western Maryland Panhandle

    Concerning...Severe Thunderstorm Watch 657...

    Valid 250602Z - 250800Z

    The severe weather threat for Severe Thunderstorm Watch 657
    continues.

    SUMMARY...Risk for damaging wind gusts continues across the Upper
    Ohio Valley area and into the central Appalachians -- in and near WW
    657.

    DISCUSSION...Latest composite radar loop shows widespread
    thunderstorms across central and northern Ohio, western and central Pennsylvania, and the West Virginia Panhandle. Aside from a cluster
    of slightly elevated/post-outflow storms over northwestern Ohio, the
    storms are largely organized into a few distinct bands.

    Two of these bands have been slower-moving, and are now crossing the
    higher terrain of the Appalachians in Pennsylvania. Weakening of
    these bands has been noted with time, as storms encounter more
    stable air along (and east of) the highest terrain.

    Meanwhile, a fast-moving, bowing band of storms continues moving
    rapidly southeastward across eastern Ohio and western Pennsylvania,
    with the fastest-moving portion of the band over western
    Pennsylvania advancing at around 55 kt. Several reports of wind
    damage have been reported over the last 1 to 2 hours with this band.

    With that said, as this band impinges on the aforementioned,
    slower-moving lines of convection to the east, and encounters the
    more stable air downstream, a gradual weakening trend is expected to
    begin over the next couple of hours. With that said, in the short
    term, damaging wind gusts are expected to continue as storms advance southeastward.
