   VALID 150915Z - 151015Z
   
   WEAK LINE OF THUNDERSTORMS ALONG COLD FRONT CONTINUES ITS
   PROGRESSION EWD ACROSS WW INTO SWRN PORTIONS OF MO AND NWRN AR. 
   LATEST RADAR TRENDS SUGGEST THIS ACTIVITY IS STRUGGLING DUE TO
   MARGINAL INFLOW/WEAK LOW LEVEL CONVERGENCE.  AS LLJ VEERS AND
   FOCUSES WELL DOWNSTREAM IT APPEARS THE ABILITY FOR UPDRAFTS TO
   MAINTAIN SUSTAINED INTENSITY IS DIMINISHING.
