   WEAK ENELY LLVL FLOW TO THE N OF A HEAT LOW OVER SWRN KS HAS

   COOLS AND INHIBITION BECOMES STRONGER FARTHER E. 
   
   FARTHER NW...CONVECTION CONTINUES TO STREAM OFF THE HIGHER TERRAIN
   OF NE CO WITH THE AID OF A SUB-TROPICAL WAVE MIGRATING ACROSS THE

   DEEPLY MIXED ENVIRONMENT WILL CONTINUE TO DIMINISH WITH DECREASED
