   VALID 232138Z - 232315Z
   
   STORMS MAY CONTINUE DEVELOPING NWD WITH TIME THROUGH S-CNTRL KS.
   SUPERCELLS WILL BE THE INITIAL PRIMARY THREAT...BUT STORMS COULD
   EVENTUALLY EVOLVE INTO AN MCS LATER TONIGHT. AREA IS BEING MONITORED
   FOR A POSSIBLE WW.
   
   STORMS ARE DEVELOPING NWD ALONG AN EXISTING OUTFLOW BOUNDARY INTO
   S-CNTRL KS WHERE THE ATMOSPHERE IS MODERATELY UNSTABLE. OBJECTIVE
   ANALYSIS INDICATES 2500-3000 J/KG MLCAPE FROM S-CNTRL THROUGH ERN
   KS...AND 40-45 KT EFFECTIVE VERTICAL SHEAR WILL SUPPORT SUPERCELL
   STORMS. THE LLJ WILL STRENGTHEN DURING THE EVENING...AND THIS COULD
   SUPPORT ADDITIONAL STORMS DEVELOPING FARTHER NWD INTO KS...POSSIBLY
   GROWING INTO AN MCS LATER TONIGHT.
