    Mesoscale Discussion 2260
    NWS Storm Prediction Center Norman OK
    1043 AM CST Wed Dec 11 2024

    Areas affected...portions of the central Florida Peninsula

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

    Valid 111643Z - 111815Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated severe gusts and perhaps a tornado cannot be
    ruled out this afternoon. A WW issuance is not expected.

    DISCUSSION...A surface cold front is rapidly approaching the FL
    Peninsula, preceded by a loosely organized QLCS. These storms are
    approaching a gradually destabilizing airmass, where surface
    temperatures are exceeding 80 F amid 70 F dewpoints (supporting 1500
    J/kg MLCAPE). While deep-layer shear and some low-level shear also
    precedes the line, deep-layer ascent will continue to drift away
    from FL, so shear should gradually weaken through the day. However,
    a brief window of opportunity may exist for the buoyancy/shear
    parameter space to briefly coincide to support a couple of damaging
    gusts or a tornado with the stronger updrafts. Nonetheless, the
    severe threat should remain isolated and a WW issuance is unlikely.
