   NWS STORM PREDICTION CENTER NORMAN OK
   0613 PM CDT MON AUG 18 2003
   
   AREAS AFFECTED...EXTREME ERN CO...SWRN NEBRASKA...NWRN KS
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 182313Z - 190115Z
   
   GIVEN CURRENT CONVECTIVE TRENDS...AN ADDITIONAL WW IS NOT
   ANTICIPATED E OF WW 869.
   
   COMPLEX OF THUNDERSTORMS OVER NERN CO HAS DEVELOPED COLD POOL AND
   WILL CONTINUE EWD.  ISOLATED STRONG CELL HAS MAINTAINED ITSELF OVER
   THE PAST COUPLE HOURS AND THIS IS EXPECTED TO CONTINUE AS IT MOVES
   EWD WITH LARGE HAIL AND DAMAGING WIND POSSIBLE.  ONLY A SLIGHT
   INCREASE IN INTENSITY IS ANTICIPATED AS SYSTEM INGESTS INCREASINGLY
   MOIST INFLOW OVER WRN KS AND SWRN NEB...WHERE MIXING RATIOS ARE
   SLIGHTLY HIGHER.  INCREASING SSWLY LLJ MAY INDUCE BACKBUILDING ALONG
   SRN OUTFLOW OF CONVECTIVE SYSTEM...BUT WEAKER WIND SPEEDS ALOFT WILL
   BE ENCOUNTERED AS IT CONTINUES EWD WHICH WOULD WORK AGAINST
   ORGANIZATION.
