   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 554
   CONTINUES.
   
   STORMS WILL BEGIN TO SPREAD EAST AND SOUTH OF WW 554 SHORTLY... BUT
   ANOTHER WW IS NOT ANTICIPATED.
   
   A LOW/MID-LEVEL CYCLONIC CIRCULATION ASSOCIATED WITH THE ONGOING
   MESOSCALE CONVECTIVE SYSTEM IS GRADUALLY TURNING EASTWARD...AND WILL
   CROSS THE OHIO RIVER INTO NORTH CENTRAL KENTUCKY DURING THE NEXT
   COUPLE OF HOURS.  WITH SOUTHWESTERLY ELEVATED MOIST INFLOW BECOMING
   CUT-OFF BY CONVECTION ON THE TRAILING SURGING OUTFLOW...AND EASTERLY
   NEAR SURFACE INFLOW EMANATING FROM A COOLER AND MORE STABLE BOUNDARY
   LAYER AIR MASS ACROSS THE BLUEGRASS...CONVECTION NEAR THIS FEATURE
   PROBABLY WILL CONTINUE TO WEAKEN.  
   
   MEANWHILE...CONVECTION ON THE LEADING EDGE OF THE TRAILING OUTFLOW
   BOUNDARY...WHICH IS NOW RAPIDLY PROGRESSING INTO/THROUGH THE MIDDLE
   TENNESSEE BORDER AREA...HAS ALREADY WEAKENED CONSIDERABLY DURING THE
   PAST HOUR OR SO.  THIS GENERAL TREND IS EXPECTED TO CONTINUE AS THE
   GUST FRONT ADVANCES SOUTH OF THE STRONGER DEEP LAYER MEAN FLOW...AND
   LOW-LEVEL INFLOW BECOMES PROGRESSIVELY WEAKER.
