    Areas affected...Portions of far southeastern OH...far eastern
    KY...WV...and extreme western VA

    Concerning...Severe potential...Watch unlikely=20

    Valid 151816Z - 152045Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A small cluster of thunderstorms may persist and pose an
    isolated threat for mainly damaging winds this afternoon. Watch
    issuance is unlikely.

    DISCUSSION...A loosely organized cluster of thunderstorms is ongoing
    along and near the OH/WV border early this afternoon. Filtered
    daytime heating ahead of this activity has allowed surface
    temperatures to increase into the mid 80s to low 90s across much of
    WV. Corresponding modest steepening of 0-3 km lapse rates has
    occurred in response per latest mesoanalysis estimates, with about
    1000-1500 J/kg of MLCAPE also present. Recent VWPs from KRLX show
    modest southerly low-level winds gradually veering and strengthening
    to around 40-45 kt above 6 km AGL. Resultant effective bulk shear of
    30-40 kt will easily support continued organization with the ongoing
    small cluster as it moves eastward across much of WV over the next
    few hours. Even though mid-level lapse rates remain poor, there may
    also be some potential for a supercell posing an isolated hail
    threat. Regardless, the lack of stronger instability should tend to
    keep the overall damaging wind threat fairly isolated, and watch
    issuance appears unlikely at this time.
