    Areas affected...Southern MS/AL into the FL Panhandle

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

    Valid 212014Z - 212245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated strong to severe storms are possible this
    afternoon.

    DISCUSSION...Convection is gradually increasing in coverage early
    this afternoon from southeast MS into south AL, along and ahead of a southward-sagging cold front. Some recovery has occurred this
    afternoon to the north of the initial wind shift, with the leading
    edge of the deeper cold and stable air still across parts of central
    MS/AL, to the north of the developing storms.=20

    MLCAPE of 1000-1500 J/kg and strong deep-layer shear are
    conditionally favorable for organized storm structures, including
    supercells. However, aside from weakly confluent flow near the
    front, forcing for ascent is expected to remain generally
    weak/nebulous across the region through the afternoon. The modest
    ascent and a warm layer based around 700 mb (as observed on the 18Z
    LIX sounding) may result in only slow intensification of the
    developing storms and generally isolated severe coverage, though a
    couple splitting supercells and/or small bowing segments may evolve
    with time. If developing convection can mature and be sustained
    near/south of the front, then some threat for isolated hail and
    damaging winds could evolve this afternoon.
