   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
