   NWS STORM PREDICTION CENTER NORMAN OK
   1210 PM CDT SUN SEP 30 2007
   
   AREAS AFFECTED...ERN KS...SERN NEB...WRN MO...SWRN IA
   
   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 
   
   VALID 301710Z - 301815Z
   
   LINE OF THUNDERSTORMS IS EXPECTED TO DEVELOP THIS AFTERNOON OVER
   EASTERN KS AND MOVE INTO WESTERN MO.  WW IS LIKELY FOR PARTS OF THIS
   AREA SOON.
   
   LATEST SURFACE ANALYSIS SHOWS POWERFUL COLD FRONT SURGING EASTWARD
   ACROSS KS.  MEANWHILE...LOW LEVEL MOISTURE IS STREAMING NORTHWARD
   AHEAD OF FRONT ACROSS EASTERN KS...WHERE DEWPOINTS ARE NOW IN THE
   LOW TO MID 60S.  CLOUDS ARE LIMITING DAYTIME HEATING...AND WILL
   LIKELY MAINTAIN SOME CAPPING INVERSION THROUGH THE AFTERNOON. 
   NEVERTHELESS...STRONG FORCING ALONG THE FRONT WILL LIKELY HELP TO
   INITIATE SCATTERED THUNDERSTORMS BY AROUND 20Z.  ACTIVITY SHOULD
   RACE RAPIDLY NORTHEASTWARD WITH AN EVOLUTION TOWARD BOWING LINE
   SEGMENTS.  VERTICAL SHEAR IS SOMEWHAT FAVORABLE FOR SUPERCELLS AND
   ISOLATED TORNADOES.  HOWEVER...THERMODYNAMIC WEAKNESSES SUGGEST THAT
   PRIMARY THREAT WILL BE DAMAGING WINDS.  WW WILL LIKELY BE ISSUED
   SOON FOR THIS AREA IN THE NEXT 1-2 HOURS.
