    Areas affected...Eastern Alabama into northern Georgia

    Concerning...Severe Thunderstorm Watch 221...

    Valid 040014Z - 040215Z

    The severe weather threat for Severe Thunderstorm Watch 221
    continues.

    SUMMARY...The potential for damaging gusts and perhaps brief
    embedded circulations continues across eastern Alabama and northern
    Georgia.

    DISCUSSION...Over the past 30 minutes, GOES IR imagery show
    gradually warming cloud-top temperatures associated with an
    organized squall line across north-central GA. This weakening trend
    is likely associated with the recent onset of the early-evening
    transition with temperatures beginning to fall into the mid 60s.
    Continued nocturnal cooling/stabilization should continue the
    weakening trend, though recent surface observations and high-res
    guidance suggests that damaging winds (generally 35-55 mph) may
    persist for the next couple of hours given the adequately sheared
    and buoyant environment.=20

    Further south across eastern AL into far western GA, warmer
    temperatures have allowed for continued storm development ahead of
    the line. The ingestion of the new cells appears to be locally
    reinforcing the cold pool as small-scale outflow surges are noted in
    KMXX and KFFC velocity data, and a stronger mid-level wind surge is
    observable from KBMX. These trends suggest that eastern AL into far
    western GA may see the best potential for a severe gust over the
    next 1-2 hours. Additionally, short-lived embedded circulation
    continue to be noted within the past hour, and this potential should
    persist given the aforementioned outflow surges within an adequately
    sheared environment. Heading deeper into the evening hours, the
    overall severe threat should begin to wane as nocturnal
    stabilization continues to hinder surface-based convection.
