    Areas affected...Northwest Ohio

    Concerning...Severe Thunderstorm Watch 332...

    Valid 062044Z - 062145Z

    The severe weather threat for Severe Thunderstorm Watch 332
    continues.

    SUMMARY...An isolated wind damage threat may affect northwest Ohio
    late this afternoon but a weather watch is not anticipated.

    DISCUSSION...The latest radar imagery shows a line of strong
    thunderstorms in far northwest Ohio extending into far southeast
    lower Michigan. The line is located along a gradient of moderate
    instability where MLCAPE values are in the 2000 to 2500 J/kg range.
    The line is also located along the southern edge of a belt of
    enhanced mid-level flow. The WSR-88D VWP in northern Indiana shows
    0-6 km shear of 30 kt along with some directional shear in the
    lowest 1 km AGL. This combined with steep low-level lapse rates may
    be enough for an isolated wind damage threat over the next few hours
    as the line moves southeastward. However, the threat should be
    marginal and a weather watch will probably not be needed.
