   VALID 032236Z - 040000Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   234...235...CONTINUES.
   
   DERECHO WAS BEGINNING TO DIMINISH...BUT LAST VESTIGES OF THE BOW
   ECHO CONTINUE TO HAVE THE POTENTIAL FOR DMGG WINDS/ISOLD BRIEF
   TORNADOES ACROSS ESPECIALLY CNTRL/NRN GA THROUGH 00Z AT LEAST.
   
   STRONGEST TSTMS HAVE BEEN FAVORING A ZONE ACROSS CNTRL/NRN GA WHERE
   AIR MASS HEATED THE MOST TODAY AMIDST COMPARATIVELY RICHER BOUNDARY
   LAYER MOISTURE THAN FARTHER TO THE S.  LINE IS MOVING ROUGHLY 260/40
   AND SHOULD REACH THE ERN END OF WW 235 BY 00Z.  BY THEN...BOUNDARY
   LAYER SHOULD BEGIN TO STABILIZE AND BECOME MORE HOSTILE AT
   SUPPORTING WIDESPREAD SVR WEATHER.  THERE WILL BE SOME CONTINUING
   THREAT OF DMGG WINDS INTO UPSTATE SC LATER THIS EVENING...GENERALLY
   SINCE THE LINE OF STORMS WILL CONTINUE NEWD WITHIN A 60 KT MID-LVL
   JET CORE.  HOWEVER...IT IS NOT YET CLEAR ON WHETHER ANOTHER WW WILL
   BE NEEDED.
   
   MEANWHILE...THROUGH 00Z...THREAT FOR DMGG WINDS WILL ACCOMPANY THE
   LINE.  FFC VWP SAMPLED AROUND 200 M2/S2 0-1KM SRH JUST BEFORE THE
   STORMS MOVED THROUGH THE RADAR SITE...AND EMBEDDED ROTATING
   COMMA-HEAD FEATURES WILL KEEP THE THREAT FOR AN ISOLD BRIEF TORNADO
   ALIVE AS WELL.
