    Areas affected...West-central Georgia

    Concerning...Severe Thunderstorm Watch 110...

    Valid 250102Z - 250200Z

    The severe weather threat for Severe Thunderstorm Watch 110

    SUMMARY...Sporadic wind damage will remain possible with a line of thunderstorms moving across central Georgia. A gradual weakening
    trend is expected as this line moves eastward after 10 PM EDT.

    DISCUSSION...The line of clustered supercells has consolidated into
    a squall line as it moves across western GA. Although the hail
    threat has greatly diminished with these storms, sporadic wind
    damage reports have been noted into the Atlanta metro, including a
    76 mph report from ATL. Wind damage will remain possible with this
    line in the near term thanks to strong 50 knot flow within the
    lowest 2 km (per KFFC VWP obs). However, the 00 UTC FFC sounding
    shows limited instability, and the onset of diurnal cooling along
    with residual cold pool air across central GA are further limiting
    factors for this line as it continues east. Recent IR imagery shows
    warming cloud tops, suggesting that gradual weakening is already
    underway. This trend will likely continue through 10 PM EDT, and
    Watch 110 will likely be allowed to expire.
