   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   337...340...CONTINUES.
   
   MATURE BOW ECHO NOW CROSSING THE MS DELTA AT ABOUT 35KT EXPECTED TO
   CONTINUE TO GRADUALLY WEAKEN THROUGH THIS EVENING WHILE MOVING
   ACROSS SRN MS. ADDITIONAL WATCHES ARE NOT CURRENTLY PLANNED BUT
   LOCAL EXTENSIONS REMAIN POSSIBLE FOR A COUPLE OF HOURS.
   
   LONG-TERM LOOPS OF RADAR AND LIGHTNING DATA APPEAR TO SUGGEST THAT
   EARLIER CONSOLIDATED BOW HAS BECOME MORE FRACTURED OVER THE PAST
   SEVERAL HOURS AND FORWARD SPEED HAS ALSO DIMINISHED SLOWLY. NEW
   CONVECTIVE DEVELOPMENT HAS BEEN NOTED IN THE WAKE OF THE
   MCS...ACROSS PARTS OF WRN LA...AS WELL AS ALONG THE NRN AND SRN
   OUTFLOWS...NEAR THE GULF COAST...AND ACROSS SRN AR. THERE ALSO
   REMAIN A FEW INTENSE UPDRAFTS WITHIN THE LEADING EDGE OF THE BOW 
   COMPLEX ITSELF BUT THESE APPEAR TO BE TRENDING WEAKER AS CONVERGENCE
   AHEAD OF THE SYSTEM DIMINISHES. WARM AND DRY BOUNDARY LAYER AIR MASS
   AHEAD OF THE SYSTEM COULD STILL SUPPORT A FEW STRONG GUSTS FROM
   DECAYING STORMS THROUGH THIS EVENING. FURTHERMORE...OUTFLOW/FRONT
   INTERSECTION ACROSS SERN AR COULD LEAD TO A FEW PERSISTENT AND
   INTENSE STORMS ACROSS THIS AREA. HOWEVER...GIVEN LATEST TRENDS AND
   THE APPEARANCE THAT THE SYSTEM HAS BEGUN TO LOSE SOME OF ITS EARLIER
   INTEGRITY...SEVERE THREAT SHOULD GRADUALLY DIMINISH WITH TIME AND NO
   ADDITIONAL WATCHES ARE EXPECTED.
