    Areas affected...Southern Georgia into northern Florida

    Concerning...Severe Thunderstorm Watch 532...

    Valid 292040Z - 292245Z

    The severe weather threat for Severe Thunderstorm Watch 532
    continues.

    SUMMARY...The potential for damaging wind, and perhaps brief
    instances of large hail, continues for portions of northern Georgia
    and southern Florida.

    DISCUSSION...Radar trends over the past hour depict mostly
    short-lived pulse convection and outflow-dominant clusters across
    southern GA. Although much of this activity has struggled to
    maintain intensity (mainly owing to the limited kinematic
    environment as sampled by regional VWPs), several instances of wind
    damage have been noted with the more robust convective cores and
    attendant downdrafts. Regionally, thermodynamic conditions remain
    supportive of intense updrafts (as evident by periodic bursts of
    colder cloud tops in GOES IR imagery and occasional MESH cores) with
    MLCAPE remaining near 2500-3000 J/kg and low-level lapse rates
    around 8 C/km away from the deeper convective cold pools. A
    combination of continued ascent along a weak front and along
    colliding outflow boundaries should continue to promote scattered,
    but relatively transient, convection capable of damaging wind swaths
    and perhaps brief instances of large hail (most likely near 1 inch).

    Further west into southern Alabama, thunderstorms are beginning to
    develop along the diffuse cold front and within a similar
    thermodynamic and kinematic environment. As with southern GA, storms
    developing across southern AL will most likely exhibit pulse-like
    behavior with some degree of clustering possible. Damaging downburst
    winds will be the primary hazard, though isolated instances of large
    hail will be possible with the more intense updraft pulses. Weaker
    frontal forcing should promote more isolated thunderstorm coverage.
