   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 288
   CONTINUES.
   
   SEVERE THREAT APPEARS TO BE COMING INCREASINGLY LOCALIZED.  THE NEED
   FOR A NEW WW IS NOT ANTICIPATED UPON 01Z EXPIRATION OF WW 288.
   
   INSTABILITY REMAINS MAXIMIZED TO THE SOUTH/EAST OF DECAYING STORM
   CLUSTER OVER CENTRAL/SOUTHWESTERN LOUISIANA...WITH MIXED LAYER CAPE
   AROUND 2000 J/KG.  AND...FORCING ASSOCIATED WITH AN AREA OF WEAK
   WARM ADVECTION MAY CONTRIBUTE TO THE CONSOLIDATION OF SCATTERED
   RECENT STORM DEVELOPMENT AROUND BATON ROUGE AND ADJACENT AREAS OF
   LOUISIANA TO THE WEST/NORTH OF LAKE PONTCHARTRAIN.  AS THIS OCCURS
   ...INTENSE UPDRAFTS MAY CONTINUE TO SUPPORT SMALL OR MARGINALLY
   SEVERE HAIL.  EVENTUALLY...PRECIPITATION LOADING MAY BECOME
   SUPPORTIVE OF A STRONG DOWNBURST TO THE SOUTH AND WEST OF THE
   LAKE...AS LIGHT NORTHWESTERLY MID-LEVEL FLOW SUPPORTS SOUTHEASTWARD
   STORM MOTION THROUGH 01-02Z.
