    Concerning...Severe Thunderstorm Watch 598...

    Valid 070615Z - 070815Z

    The severe weather threat for Severe Thunderstorm Watch 598
    continues.

    SUMMARY...An isolated wind-damage and hail threat will likely
    continue for a few more hours from southern Illinois, southern
    Indiana and southern Ohio, gradually developing east-southeastward
    into western and northern Kentucky.

    DISCUSSION...The latest high-resolution radar from Louisville shows
    an MCS just to the northern of the Ohio River across north-central
    Kentucky, far southern Indiana and far southern Illinois. This
    feature will continue to track east-southeastward along the northern
    edge of moderate instability, where the RAP is estimating MLCAPE in
    the 1000 to 1500 J/kg range. In addition to the instability, the MCS
    is being supported by large-scale ascent ahead of a shortwave trough
    moving through the mid Mississippi Valley. Ahead of the trough, the
    latest WSR-88D VWP at Louisville has strong speed shear in the
    low-levels, which is contributing to about 45 kt of 0-6 km shear.
    This wind profile will continue to support strong multicell line
    segments capable of isolated wind damage and hail.
