    Areas affected...Much of Georgia...eastern Alabama... into far
    western South Carolina

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

    Valid 241755Z - 242000Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Scattered thunderstorms may pose a risk for occasional
    damaging gusts this afternoon. Storm organization will be limited
    and a WW is unlikely.

    DISCUSSION...As of 1745 UTC, visible and radar imagery showed
    thunderstorms increasing in coverage over eastern AL, FL and much of
    GA. Ample heating is occurring within a very moist air mass (70s F
    dewpoints) supporting moderate instability. While low and mid-level
    flow are quite weak, locally stronger convergence is occurring near
    a broad MCV along the AL/GA border. This will continue to serve as a
    focus for convective development this afternoon, with additional
    storms likely to develop within the warm sector as convective
    temperatures are breached. One or more clusters of stronger storms
    appears plausible, with convection gradually spreading
    east/northeastward into SC this afternoon/evening.

    Given the very weak vertical shear, pulse multicellular storms are
    the expected mode. Heavy water loading (PWATS near or exceeding 2
    inches) will favor damaging gust potential with the stronger
    downdrafts. But, the lack of broader upper air support and very weak
    shear suggests the threat will be isolated and dependent on
    favorable outflow interactions and storm-scale clustering. With the
    severe potential likely to be sporadic, a WW is very unlikely.
