   Areas affected...Southern Appalachians/Piedmont

   Concerning...Severe potential...Watch unlikely 

   Valid 191911Z - 192115Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated wind damage is possible with scattered storms
   this afternoon. Lack of organization should preclude watch issuance
   this afternoon.

   DISCUSSION...Convection over the course of the last couple of hours
   has remained rather weak with a few cells becoming briefly
   marginally severe. Area VAD data shows 0-6 km shear of 15-20 kt.
   This should continue to promote disorganized cells that may
   occasionally pulse in intensity. A corridor of low 90s F
   temperatures and steeper low-level lapse rates in northern Georgia
   into Upstate South Carolina could see a locally greater risk of
   isolated wind damage. Barring greater cold pool organization of
   activity, a watch is not anticipated this afternoon.
