...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE
SOUTHEAST...

...SUMMARY...
A wind-damage and isolated tornado threat exists across parts of the
Southeast. Marginally severe wind gusts will also be possible
northeastward into parts of the southern Appalachians and southern
Virginia.

...Southeast...
A composite squall line with some embedded bows, along with some
preceding thunderstorms and occasional transient/mostly weak
supercells thus far, extends from the Alabama/Georgia border
vicinity (west/southwest of Atlanta metro) southwestward into
east-central Alabama and southwest Alabama near Mobile as of 1130am
CDT/1230pm EDT. Multi-layer cloud cover extends across the nearby
warm sector to its east, but a moist environment (upper 60s/near
70F) and some additional heating will lead to further
destabilization, a change that should most appreciably occur
northeastward into western/north-central Georgia owing to
differential heating and essentially a northeastward-advancing warm
front. The strongest forcing for ascent and deep-layer winds will
lag (to the west-northeast) the composite convective line, but
sufficient vertical shear extends into the warm sector to support
organized storm modes including semi-discrete supercells and
line-embedded bows. Damaging wind and tornado risks will exist
through at least early/mid-evening.

...Southern Appalachians/Piedmont...
Warmer air aloft is expected to have a greater influence over these
regions. With less buoyancy anticipated through the afternoon,
convective intensity should remain muted. Given the strong shear
across these areas, a few strong to severe storms may produce
isolated wind damage.
