Areas affected...Northern Alabama...northwest Georgia...and
southeast Tennessee

Concerning...Severe Thunderstorm Watch 271...

Valid 120250Z - 120415Z

The severe weather threat for Severe Thunderstorm Watch 271
continues.

SUMMARY...Line of thunderstorms will sag southward across the region
through midnight, posing a risk of locally damaging wind gusts.

DISCUSSION...Latest radar imagery shows a line of strong to severe
storms extending roughly from south of Tupelo MS to south of
Huntsville AL. Intensities along the line have been generally
sub-severe so far. However, winds aloft are quite strong (3-5km
winds of 30-40 knots on GWX and HTX VAD profiles) and several weak
bowing structures continue to be observed. Given the moist and
moderately unstable air mass that is present ahead of the storms,
and the continued signal in evening CAM guidance for a robust squall
line, the potential for locally damaging wind gusts will continue
into the early morning hours.
