    Probability of Watch Issuance...5 percent

    SUMMARY...Loosely organized multicellular convection will continue
    to increase in coverage throughout the afternoon. Marginally severe
    hail and wind gusts are possible.

    DISCUSSION...A surface front was reinforced and pushed south near
    the Ohio River from overnight/morning convection with new convective
    initiation along this boundary stretching from eastern Kentucky back
    to southeastern Missouri. Surface dewpoints are in the low-mid 70s
    with temperatures reaching the mid-upper 80s helping destabilize
    lower levels across this region. MLCAPE of 1000-2000 J/kg, but weak
    flow aloft and shear indicates continued development of
    multicellular, loosely organized clusters across this region through
    the evening firing along the boundary and subsequent outflow
    boundaries from ongoing convection. Hail and strong wind gusts are
    possible within the stronger cells.
