   AREAS AFFECTED...ERN SC...NE FL
   
   CONCERNING...TORNADO WATCH 21...
   
   VALID 221849Z - 222045Z
   
   EXTENSIVE SQUALL LINE CONTINUES TO ADVANCE EASTWARD...AND WILL
   CLEAR MUCH OF COASTAL SOUTH CAROLINA/GEORGIA AND THE JACKSONVILLE
   AREA BY 20Z.  DAYTIME HEATING/MIXING HAS LOWERED SURFACE DEW
   POINTS ACROSS NORTHEAST FLORIDA.  THIS APPEARS TO CONTRIBUTE TO
   DECREASING POTENTIAL FOR TORNADOES IN KINEMATIC ENVIRONMENT WITH
   MOSTLY UNIDIRECTION WIND PROFILES.  HOWEVER...RELATIVELY DEEP
   WELL MIXED BOUNDARY LAYER WILL REMAIN SUPPORTIVE OF DAMAGING
   SURFACE GUSTS ANOTHER FEW HOURS...WITH MARGINALLY SEVERE HAIL
   ALSO POSSIBLE NEAR STRONGEST UPDRAFTS.
