Areas affected...far western North Carolina...northwestern South
Carolina...and northeastern Georgia

Concerning...Severe potential...Watch possible

Valid 090231Z - 090400Z

Probability of Watch Issuance...60 percent

SUMMARY...Severe/supercell storms moving across southern
Appalachians will begin to spread east of WW 211 in the next hour.
New WW may be required.

DISCUSSION...Latest radar shows strong/severe storms -- including
embedded supercells -- moving eastward across eastern Tennessee,
northern Alabama, and northwestern Georgia.  Hints of upscale growth
into banded structures is indicated within the overall area of
widespread convection, with likelihood that convection will continue
over the next few hours.

As such, storms will begin spreading out of WW 211 over the next
hour or so.  The downstream airmass in lee of the Appalachians is
less unstable, particularly from northeastern Tennessee into
northern and central North Carolina.  Convection moving into
northeastern Tennessee has shown a gradual weakening trend,
confirming the less-favorable airmass.

However, across far southwestern North Carolina and northwestern
South Carolina, and into northeastern Georgia, a more favorably
unstable airmass exists.  This would appear to be the most likely
area for continued severe-weather potential in the next 2 to 4
hours.  This threat -- which would include locally damaging winds,
marginal hail, and possibly a tornado or two -- may require new WW
issuance.
