   TOWERING CUMULUS ARE DEVELOPING IN THE SRN PORTION OF THE
   WW...MAINLY SOUTH OF A GLD/LIC LINE. THIS SUGGESTS THAT STORMS ARE
   TRYING TO DEVELOP. THE ENVIRONMENT IS MODERATELY UNSTABLE WITH 100MB
   MLCAPES AROUND 1000-1500 J/KG. DEEP LAYER SHEAR AROUND 50 KNOTS WILL
   SUPPORT THE DEVELOPMENT OF SUPERCELLS IF STORMS DEVELOP. THE
   POSSIBILITY FOR SEVERE THUNDERSTORMS WILL PERSIST UNTIL AROUND
   SUNSET. ANOTHER WW IS BEING ISSUED FARTHER EAST ACROSS PORTIONS OF
   NE/KS.
