   Areas affected...Eastern Tennessee...Southwestern Virginia...and far
   Western North Carolina

   Concerning...Severe potential...Watch unlikely 

   Valid 242209Z - 242315Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A few damaging wind gusts remain possible for the next 1-2
   hours, watch unlikely.

   DISCUSSION...Regional radar shows a few clusters of storms have
   emerged from diurnally driven convection over the region, with
   perhaps some assistance from a mid-level vort max evident in water
   vapor imagery. These storms have produced a few localized damaging
   wind gusts, particularly over parts of northeast Tennessee.  As
   these storms continue to drift southeast amid modest buoyancy
   (MLCAPE 1000-1500 J/kg) and weak deep-layer shear, the threat for a
   few additional damaging wind gusts will continue for the next hour
   or two. With time, a downward trend in intensity is expected with
   the loss of daytime heating and as the clusters approach a
   stabilized airmass that was modified by storms that occurred
   previously over southwestern North Carolina. Given the localized and
   transient nature of this threat, watch issuance remains unlikely.
