   VALID 241626Z - 241900Z

   SUMMARY...A GRADUAL INCREASE IN SEVERE THREAT IS POSSIBLE THROUGH

   EVOLVE AHEAD OF THE MAIN COLD FRONT...FROM NEAR TUSCALOOSA SWWD TO
   THE NEW ORLEANS VICINITY. THE STORMS OVER LA AND THE NRN GULF OF
   MEXICO ARE MORE ROBUST IN TERMS OF ECHO TOPS DUE TO CLOSER PROXIMITY

   LANGUISH ON THE NRN EDGE OF THE LOW-LEVEL THETA-E RETURN. EVEN
   SO...SOME OF THE NRN CELLS HAVE SHOWN A PROPENSITY FOR WEAK
   ROTATION.

   HODOGRAPHS AREA-WIDE ARE FAVORABLE FOR SUPERCELLS CAPABLE OF
   PRODUCING TORNADOES...WITH 0-1 SRH OF 200-300 M2/S2 AND A GRADUALLY
   MOISTENING AND DESTABILIZING AIR MASS. GIVEN SPOTTY HEATING ACROSS
   SRN AL AND WRN FL PANHANDLE...AND A GRADUAL NWD ADVECTION OF MID 60S

   DAY...WITH A WATCH POSSIBLY NEEDED.
