    Areas affected...Northeast Alabama and northwest Georgia

    Concerning...Severe Thunderstorm Watch 430...

    Valid 012052Z - 012245Z

    The severe weather threat for Severe Thunderstorm Watch 430
    continues.

    SUMMARY...An environment favorable for strong/severe downburst winds
    remains in place across portions of northeast Alabama and northwest
    Georgia.

    DISCUSSION...Over the past couple of hours, the highest
    concentration of thunderstorms has largely remained across
    north-central to northwest AL with an expanding cold pool noted in
    recent surface observations and RTMA analyses. To the east of this
    area, more isolated convection has largely left the environment
    across northeast AL into northwest GA largely intact with
    temperatures remaining in the mid 90s, low-level lapse rates near 8
    C/km, and MLCAPE values between 3500-4000 J/kg. A thunderstorm
    cluster west of the Atlanta metro has recently demonstrated an
    uptick in intensity (per GOES IR imagery and lightning trends),
    which confirms that this environment remains favorable for robust
    deep convection. While it remains unclear exactly how widespread
    thunderstorm coverage will become through the evening hours, the
    potential for strong to severe downbursts and clustering/upscale
    growth remains across eastern portions of WW 430.
