   SURFACE FRONT HAS BECOME STATIONARY ACROSS CNTRL AL SWWD INTO SRN MS
   AND SCNTRL LA. BAND OF TSTMS CONTINUES ALONG/NORTH OF THE FRONT. 
   SEVERAL CELLS WITHIN THE BAND HAVE TAKEN ON SMALL SCALE BOWS/LEWPS
   GIVEN THE UNIDIRECTIONAL SSWLY FLOW THROUGH THE COLUMN.  THESE TSTMS
   MAY POSE A DAMAGING WIND OR BRIEF TORNADO THREATS.  THERE ARE A
   COUPLE OF NEGATIVES FOR WIDESPREAD SEVERE WEATHER.  WATER VAPOR
   IMAGERY SHOWS SOME INCREASE IN UPPER LEVEL RIDGING NOTED BY
   ANTICYCLONIC ARCING MID/HIGH  LEVEL CLOUDS OVER THE WRN GULF BASIN
   AHEAD OF NEXT IMPULSE READY TO EJECT NEWD FROM S TX. 
   MOREOVER...MIDLEVEL TEMPERATURES ARE SOMEWHAT HIGH TO SUPPORT
   VIGOROUS UPDRAFTS.  NONETHELESS...LOW LEVEL FLOW IS QUITE STRONG AND
   IS RICH WITH LOW LEVEL HELICITY.  THIS MAY COMPENSATE FOR THE MODEST
   BUOYANCY AND SOMEWHAT UNFAVORABLE UPPER LEVEL RIDGING. AS SUCH...A
   NEW TORNADO WATCH WILL BE ISSUED FOR PARTS OF THE AREA BY 23 UTC. 
   THE SEVERE THREAT MAY ACTUALLY BE HIGHER LATER THIS EVENING WHEN THE
   NEXT IMPULSE APPROACHES THE LOWER MS VLY.
