   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 148 CONTINUES.
   
   IF CURRENT TRENDS CONTINUE...A NEW WW MAY NOT BE NEEDED PRIOR TO THE
   SCHEDULED 14Z EXPIRATION OF WW 148.
   
   ALTHOUGH SOME RECENT INTENSIFICATION HAS OCCURRED WITH THE STORM
   NEAR VALDOSTA...THE GENERAL TREND SO FAR HAS BEEN FOR CONVECTION TO
   WEAKEN AS IT SPREADS EAST OF THE WW AREA TOWARD ATLANTIC COASTAL
   AREAS.  LOW-LEVEL STORM RELATIVE INFLOW EMANATING FROM A RESIDUAL
   POCKET OF SLIGHTLY COOLER AND DRIER BOUNDARY LAYER AIR OVER INTERIOR
   NORTHERN FLORIDA INTO SOUTHERN GEORGIA MAY BE RESPONSIBLE...AND IT
   IS NOT CLEAR THAT SIGNIFICANT DESTABILIZATION WILL OCCUR PRIOR TO
   THE ANTICIPATED VEERING AND WEAKENING OF LOW-LEVEL FLOW FIELDS
   DURING THE MID TO LATE MORNING.
