   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 727
   CONTINUES.
   
   A LINE OF STRONG TO SEVERE STORMS HAD BECOME ALIGNED ALONG REMNANT
   QUASI-STATIONARY FRONT FROM WEST OF HSV SWWD THROUGH TUP TO NORTH OF
   GWO. ALSO...RADAR INDICATED A PRONOUNCED OUTFLOW BOUNDARY...FROM
   WEAKENING CONVECTION SOUTH OF CBM...STRETCHED FROM NEAR THE FRONT
   ABOUT 20 SW OF TUP TO WELL SOUTH OF CBM. GIVEN THE NLY FLOW ALOFT
   ...STORMS ARE EXPECTED TO REMAIN MOST INTENSE AND SEVERE AS THEY
   DROP SWD THROUGH NRN AND INTO CENTRAL MS...ALONG AND WEST OF OUTFLOW
   BOUNDARY...WHERE TEMPERATURES ARE STILL IN THE 90S WITH DEWPOINTS IN
   THE MID 70S.
   
   WHILE THE STORMS FROM WEST OF HSV TO EAST OF TUP MAY STILL BE
   SEVERE...THEY ARE LIKELY TO GRADUALLY WEAKEN THE NEXT HOUR OR SO AS
   THEY MOVE SWD INTO THE MORE STABLE AND COOLER AIR MASS LOCATED
   BEHIND OUTFLOW BOUNDARY.
