   ISOLATED SVR STORMS MAY MOVE S OUT OF WW 815 OVER NWRN KS INTO
   PORTIONS OF W-CNTRL/SWRN KS DURING THE 22-00Z TIME PERIOD. SVR
   WEATHER THREAT MAY BE ISOLATED ENOUGH TO PRECLUDE ADDITIONAL
   WW...BUT TRENDS WILL CONTINUE TO BE MONITORED.
   
   AT 2145Z...SVR STORM CAPABLE OF PRODUCING LARGE HAIL/DAMAGING WINDS
   WAS MOVING S ACROSS LOGAN COUNTY IN NWRN KS. THIS CELL IS EXPECTED
   TO CONTINUE TRACKING SWD INTO PORTIONS OF W-CNTRL/SWRN KS DURING THE
   REMAINDER OF THE AFTERNOON. AIRMASS S OF WW 815 IS CHARACTERIZED BY
   VERY HOT TEMPERATURES /100-105F/ AND STEEP LOW-LEVEL LAPSE RATES.
   STRONGEST INSTABILITY IS LOCATED ALONG AND N OF A FRONTAL BOUNDARY
   OVER NWRN KS /MLCAPE VALUES RANGING FROM 1000-2000 J PER KG/...WHERE
   MOISTURE IS HIGHER...WITH MORE MARGINAL INSTABILITY ENVIRONMENT
   POSITIONED S OF THE FRONT DUE TO THE DRIER BOUNDARY LAYER /MLCAPE
   VALUES FROM 500-1000 J PER KG/. NEVERTHELESS...THE HOT SURFACE
   AIRMASS AND INVERTED-V PROFILES MAY CONTINUE TO FAVOR A RISK FOR
   DAMAGING WINDS /IN ADDITION TO A MARGINAL THREAT FOR LARGE HAIL/.
