   CONCERNING...TORNADO WATCH 892...
   
   VALID 170547Z - 170645Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 892 CONTINUES.
   
   TORNADO WATCH 892 CONTINUES UNTIL 07Z...ALTHOUGH THE SEVERE WEATHER
   THREAT WITHIN WW 892 IS EXPECTED TO CONTINUE TO STEADILY WANE/SHIFT
   OFFSHORE. ISOLATED SEVERE WIND/PERHAPS TORNADO THREAT OTHERWISE
   PERSISTS ACROSS EXTREME/COASTAL SOUTHEAST GA IN THE SHORT TERM AS
   WELL AS FAR NORTH FL.
   
   A NORTHEAST-SOUTHWEST ORIENTED BAND OF CONVECTION CONTINUES TO SHIFT
   EAST-NORTHEAST EARLY IN THE OVERNIGHT ACROSS FAR SOUTHEAST GA AND
   THE NORTHERN FL PENINSULA. MUCH OF THE CONVECTION ACROSS SOUTHEAST
   GA CONTINUES TO BE UNDERCUT BY COMPOSITE OUTFLOW...SUCH THAT THE
   SEVERE THREAT WILL CONTINUE TO WANE IN SPITE OF A VERY STRONG DEEP
   LAYER FLOW FIELD. A SEVERE THREAT WILL OTHERWISE REMAIN ACROSS FAR
   NORTH FL AT LEAST ON AN ISOLATED/MARGINAL BASIS...NAMELY IN
   ASSOCIATION WITH ANY PERSIST QLCS STRUCTURES/SMALL BOWING
   SEGMENTS...PERHAPS ESPECIALLY AS THIS CONVECTION INTERCEPTS THE
   AFOREMENTIONED OUTFLOW BOUNDARY.
