...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.
