   AREAS AFFECTED...NERN LA/FAR SERN AR/PART OF WRN MS AND SWD TO SERN
   LA
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 2...
   
   VALID 040029Z - 040130Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 2 CONTINUES.
   
   A FEW SEVERE STORMS REMAIN POSSIBLE...MAINLY PRODUCING HAIL...
   THROUGH ABOUT 02Z ACROSS WW 02.  HOWEVER...RECENT TRENDS PER
   REGIONAL RADARS SUGGEST OVERALL SEVERE WEATHER THREAT SHOULD
   CONTINUE TO DIMINISH THROUGH 03Z...WITH WW POTENTIALLY BEING
   CANCELLED EARLY BY THE LOCAL WFOS.
   
   EARLY EVENING SURFACE ANALYSIS SHOWED A BOUNDARY EXTENDING FROM SERN
   LA NWWD THROUGH CENTRAL TO NWRN LA.  THE LOSS OF DAY TIME HEATING
   HAS RESULTED IN A DECREASING TREND IN AVAILABLE INSTABILITY WITH
   MLCAPE RANGING FROM 400-800 J/KG ACROSS ERN/SRN LA.  THE CLUSTER OF
   TSTMS THAT HAD DEVELOPED LATE THIS AFTERNOON ACROSS NORTH CENTRAL LA
   HAS ALL BUT CEASED TO EXIST WITH ONE STORM MOVING EWD THROUGH NERN
   LA.  THE TRACK OF THIS STORM TOWARD A MORE STABLE AIR MASS SUGGESTS
   THAT THIS STORM SHOULD DIMINISH IN INTENSITY.
   
   ADDITIONAL STORMS HAVE DEVELOPED S OF WW 02 WITHIN A WAA REGIME IN
   THE VICINITY OF AND E OF THE SEWD EXTENSION OF THE SURFACE BOUNDARY.
   EFFECTIVE BULK SHEAR AROUND 40 KT OVER SRN LA MAY SUPPORT A FEW
   ORGANIZED STORMS PRODUCING ISOLATED HAIL...BUT A FURTHER DECREASE IN
   INSTABILITY SHOULD LIMIT THE SEVERE THREAT ACROSS THIS REGION.
