   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 44 CONTINUES.
   
   WARM ADVECTION CONTINUES TO DRIVE A SUBSTANTIAL AMOUNT OF CONVECTION
   ACROSS TORNADO WATCH #44 THIS EVENING. AS LLJ BEGINS TO INCREASE
   ACROSS MS INTO TN IT APPEARS A GRADUAL NWD SHIFT TO ONGOING ELEVATED
   CONVECTION WILL ENSURE RAIN-COOLED AIRMASS OVER NRN GULF STATES WILL
   STUBBORNLY HOLD.  AS A RESULT...SLOWLY RETREATING NW-SE ORIENTED
   WARM FRONT WILL REMAIN THE PRIMARY FOCUS FOR NEAR-SFC BASED
   SUPERCELL DEVELOPMENT.  DURING THE LAST HOUR OR SO A POTENTIALLY
   TORNADIC CYCLICAL SUPERCELL HAS TRACKED ACROSS CNTRL LA AND AT 0330Z
   IS JUST SE OF ESF.  THIS STORM SHOULD ENCOUNTER THE WARM FRONT OVER
   NERN LA BEFORE LIFTING ATOP AFOREMENTIONED COOLER AIRMASS.  OTHER
   STORMS HAVE STRUGGLED TO ATTAIN ANY MEANINGFUL INTENSITY ALONG
   SURGING COLD FRONT AS IT SWEEPS ACROSS NWRN PORTIONS OF WW.
