    Mesoscale Discussion 2066

    1251 PM CDT Fri Sep 13 2024

    Areas affected...Parts of the FL Panhandle into southeast
    AL/southwest GA

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

    Valid 131751Z - 131945Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Locally damaging wind and perhaps a tornado are possible
    this afternoon.

    DISCUSSION...A small thunderstorm cluster has recently become better
    organized across the FL Panhandle. The KEVX VWP depicts backed (but
    also relatively weak) low-level flow with modest southwesterly flow
    aloft, supporting effective shear of 30-35 kt. Modest heating is
    ongoing downstream of this cluster, with MLCAPE increasing into the
    1000-1500 J/kg range. This may help to sustain the ongoing cluster,
    along with some potential for additional development into southwest
    GA with time. Locally damaging gusts will be possible, along with
    some potential for a tornado where surface flow remains backed
    through the afternoon.
