    Areas affected...Northeast Ohio...northwest Pennsylvania...and far

    Concerning...Severe Thunderstorm Watch 195...

    Valid 092239Z - 092345Z

    The severe weather threat for Severe Thunderstorm Watch 195
    continues.

    SUMMARY...A locally favorable corridor for damaging wind gusts is
    evident from northeast Ohio into northwest Pennsylvania for the next
    2 hours or so.

    DISCUSSION...A few deeper/stronger cores are evolving along the band
    of storms moving from Lake Erie into northeast OH and northwest PA.
    Within WW175, a locally favorable corridor for damaging winds gusts
    is evident here, given 35-40 kt of line-oblique cloud-bearing shear
    (per CLE VWP) and steepened pre-convective lapse rates. Damaging
    gusts of 55-65 mph appear most likely in this corridor over the next
    2 hours or so.
