   VALID 242203Z - 242300Z
   
   SUPERCELL STORMS WILL CONTINUE DEVELOPING NORTHWARD INTO NRN KS NEXT
   FEW HOUR. ACTIVITY MAY EVENTUALLY SPREAD INTO EXTREME SRN NEB.
   TORNADOES AND LARGE HAIL WILL BE THE PRIMARY THREATS.
   
   EARLY THIS EVENING A LINE OF DISCRETE SUPERCELLS ARE LIFTING NWD
   THROUGH CNTRL AND S-CNTRL KS. SOME OF THE STORMS ARE APPROACHING THE
   NRN EDGE OF WW 360. A FRONT EXTENDS FROM NERN KS WWD THROUGH N-CNTRL
   KS. BOUNDARY LAYER IS COOLER...AND INSTABILITY GRADUALLY DECREASES
   WITH NWD EXTENT AWAY FROM THE FRONT...BUT THE THERMODYNAMIC
   ENVIRONMENT IS SUFFICIENT FOR SURFACE BASED STORMS. LARGE 0-1 KM
   HODOGRAPHS WILL REMAIN VERY FAVORABLE FOR LOW LEVEL MESOCYCLONES AND
   TORNADOES AS THE LLJ INCREASES THIS EVENING.
