    Areas affected...Ohio Valley

    Concerning...Severe potential...Watch possible=20

    Valid 072336Z - 080030Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Severe threat appears to be increasing across the southern
    Ohio Valley this evening. New watch appears warranted and may be
    issued by soon.

    DISCUSSION...Persistent corridor of low-level confluence extends
    along the confluence of the MS/OH River into southern IN. Agitated
    cu field is gradually deepening across southern IL/IN into western
    KY where MLCAPE values are in excess of 3000 J/kg. Given the strong,
    deep-layer shear across this region, robust updrafts may evolve over
    the next few hours. Supercell risk is increasing and a new ww
    appears warranted.
