    Concerning...Severe Thunderstorm Watch 485...

    Valid 292130Z - 292300Z

    The severe weather threat for Severe Thunderstorm Watch 485
    continues.

    SUMMARY...A threat for damaging wind gusts from 55-70 mph will
    remain probable with a small bowing cluster moving east-southeast
    towards the central Ohio Valley.

    DISCUSSION...A small bowing cluster was ongoing between the I-70 and
    I-74 corridors in the eastern IN. The Indianapolis VWP in the wake
    of this cluster continues to sample a belt of 35-50 kt mid-level
    westerlies which will aid in sustaining convective organization as
    this cluster likely tracks east-southeastward over the next few
    hours. Incipient Cb development is also occurring farther south
    closer to the OH River in southeast IN. It is plausible this may
    merge into the cluster across the IN/OH/KY border area and yield an
    overall southeast shift to convective development. This should
    spread across the I-75/I-71 corridors in southwest OH to northern
    KY. The greatest threat for damaging winds should be focused near
    the apex of the small bow.
