    Areas affected...portions of central and eastern Alabama into
    western Georgia

    Concerning...Severe Thunderstorm Watch 30...

    Valid 100143Z - 100315Z

    The severe weather threat for Severe Thunderstorm Watch 30
    continues.

    SUMMARY...An MCS will continue to move east/southward across AL/GA
    this evening with a risk for damaging gusts.

    DISCUSSION...As of 0140 UTC, regional radar imagery showed an
    initially loosely organized cluster of thunderstorms had developed
    into an MCS across portions of AL and western GA. The environment
    remains broadly unstable and moderately sheared across much of the
    southeast, which should continue to maintain organized bowing
    segments and supercells.

    While not overly intense, more organization has been noted within
    the MCS over the last two hours, suggesting a consolidated cold pool
    and stronger surface pressure gradient has developed. This will
    support the potential for damaging gusts (max 60-65 mph), and
    possibly a QLCS tornado or two as the convective complex continues east/southeastward into parts of eastern AL and west-central GA
    (including the Atlanta Metro in 1-2 hours) this evening.

    Additional strong thunderstorms, including a few supercells, will
    remain possible on the upshear side of the complex over central AL.
    Additional upscale growth appears likely with time. This would favor
    damaging gusts and some hail potential with the stronger supercells.
    Given the persistent severe threat, WW30 remains in effect until
    0300 UTC, but may be locally extended in time and area as convection
    continues to move through AL/GA.
