    Areas affected...central and eastern Kentucky...far southern
    Ohio...and West Virginia

    Concerning...Severe Thunderstorm Watch 138...

    Valid 142130Z - 142300Z

    The severe weather threat for Severe Thunderstorm Watch 138
    continues.

    SUMMARY...Multiple supercells capable of large hail and damaging
    wind gusts will persist this evening.

    DISCUSSION...A cluster of supercells has developed across southern
    Ohio with multiple large hail reports received thus far. The
    strongest of these cells is a lead supercell approaching Charleston,
    WV as of 2130 UTC. This supercell has a history of 2 inch hail and
    latest MRMS data suggests 2+ inch hail (perhaps the size of
    baseballs) remains possible. The environment downstream of this
    supercell remains favorable with 750-1000 J/kg MLCAPE and 45 to 50
    knots of shear and visible satellite showing an expansive agitated
    cumulus field. Therefore, expect this 2+ inch hail threat to persist
    for at least a few more hours across West Virginia.

    Thunderstorm activity has been limited south of the Ohio River thus
    far, and visible satellite imagery does not appear to indicate
    additional thunderstorms are imminent. However, the environment
    remains uncapped and as mid-level temperatures continue to cool,
    some thunderstorms will be possible along the front this evening.
