   AREAS AFFECTED...FAR SRN MS/AL...SERN/SCENTRAL LA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 131858Z - 132100Z
   
   SCT TSTMS SHOULD DEVELOP AND INTENSIFY OVER THE AREA IN THE NEXT FEW
   HOURS. ISOLATED DMGG WINDS WILL BE POSSIBLE WITH THE STRONGEST
   TSTMS...BUT A WW IS NOT EXPECTED.
   
   SFC MESOANALYSIS INDICATED AN AREA OF LOW PRESSURE LOCATED OVER SERN
   LA /NEAR NEW ORLEANS...WITH A STATIONARY BOUNDARY EXTENDING WWD
   ACROSS SRN LA...AND SEVERAL SEA BREEZE BOUNDARIES OVER FAR SERN
   LA...FAR SRN MS/AL. THESE BOUNDARIES SHOULD AID TO FOCUS SCT-NMRS
   TSTMS A VERY UNSTABLE AIRMASS WAS IN PLACE WITH MLCAPES FROM
   2500-3500 J/KG. THE AREA REMAINS ON THE WRN EXTREMITY OF BROAD NLY
   FLOW AROUND AN UPPER LOW OVER SERN GA...WITH RECENT SLIDELL VWP DATA
   INDICATING 15-20 KTS OF MID LEVEL FLOW. GIVEN LOW LEVEL SLY
   FLOW...THERE SHOULD EXIST ENOUGH SHEAR FOR WEAKLY ORGANIZED
   MULTICELLULAR CLUSTERS. DRY MID LEVELS COMBINED WITH STEEP LOW LEVEL
   LAPSE RATES WILL SUPPORT SOME DMGG WIND THREAT. RELATIVELY MARGINAL
   MID LEVEL LAPSE RATES AND HIGH WBZ HEIGHTS SHOULD ALSO LIMIT THE SVR
   HAIL THREAT. GIVEN THE EXPECTED WEAK ORGANIZATION AND MARGINAL SVR
   THREAT...A WW IS NOT EXPECTED.
