   CONCERNING...TORNADO WATCH 88...91...

   VALID 202245Z - 202345Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 88...91...CONTINUES.

   SUMMARY...ISOLATED SEVERE THUNDERSTORMS REMAIN POSSIBLE FROM PARTS
   OF NORTHEAST GA INTO NORTHERN SC.

   DISCUSSION...LATEST VIS IMAGERY SUGGESTS PRIMARY ZONE OF LOW-LEVEL
   CONFLUENCE EXTENDS FROM FAYETTE COUNTY GA...NEWD THROUGH MADISON
   COUNTY GA...INTO LANCASTER COUNTY SC.  STRONGEST UPDRAFTS ARE
   PRODUCING LIGHTNING ALONG THIS BAND OF DEEPER CONVECTION BUT ARE
   STRUGGLING TO MAINTAIN INTENSITY...POSSIBLY DUE TO LARGE SCALE
   FORCING FOCUSED WELL NORTH OF THIS REGION.  DEEP SHEAR IS MORE THAN
   ADEQUATE FOR ORGANIZED CONVECTION AND FOR THIS REASON ISOLATED
   SUPERCELLS AND PERHAPS A TORNADO OR TWO CAN BE EXPECTED.  LATER THIS
   EVENING...BOUNDARY LAYER COOLING SHOULD RESULT IN FURTHER WEAKENING.
