   NWS STORM PREDICTION CENTER NORMAN OK
   1133 AM CDT WED JUN 11 2008
   
   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CORN BELT AND
   MID-MISSOURI RIVER VALLEY LATER TODAY AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS EXPECTING THE
   DEVELOPMENT OF A FEW STRONG TORNADOES OVER PARTS OF THE CORN BELT
   AND MID-MISSOURI RIVER VALLEY LATER TODAY AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          WESTERN IOWA
          SOUTHERN MINNESOTA
          EASTERN NEBRASKA
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM...THE UPPER
   MISSISSIPPI RIVER VALLEY AND EASTERN DAKOTAS SOUTHWARD INTO THE
   CENTRAL AND SOUTHERN PLAINS STATES
   
   A POTENT UPPER LEVEL STORM SYSTEM AND ASSOCIATED BELT OF STRONG
   MID-LEVEL FLOW OVER THE NORTHERN AND CENTRAL ROCKIES EARLY TODAY
   WILL MOVE TO THE NORTHERN AND CENTRAL PLAINS THIS AFTERNOON AND
   EVENING.  AHEAD OF THIS SYSTEM...STRONG LOW-LEVEL WINDS WERE
   TRANSPORTING A MOIST AIR MASS NORTHWARD THROUGH THE PLAINS.  THIS
   WILL MAINTAIN MORNING THUNDERSTORM CLUSTERS FROM KANSAS AND MISSOURI
   NORTHWARD INTO MINNESOTA AND THE EASTERN DAKOTAS.  A FEW OF THESE
   STORMS MAY PRODUCE LARGE HAIL AND DAMAGING THUNDERSTORM WIND GUSTS.
   
   THUNDERSTORMS WILL DEVELOP THIS AFTERNOON ALONG AND AHEAD OF SURFACE
   COLD FRONT FROM SOUTHEAST SOUTH DAKOTA INTO CENTRAL KS.  COMBINATION
   OF STRONG TROPOSPHERIC WINDS AND MAGNITUDE OF EXPECTED INSTABILITY
   WILL MAKE FOR A FAVORABLE SUPERCELL ENVIRONMENT WITH VERY LARGE HAIL
   LIKELY.  IN ADDITION...SUFFICIENT LOW-LEVEL SHEAR WILL BE PRESENT
   FOR A FEW STRONG TORNADOES THROUGH MID-EVENING ACROSS THE MODERATE
   RISK AREA.
   
   SEVERE THUNDERSTORMS WILL LIKELY ALSO DEVELOP SOUTHWARD INTO CENTRAL
   KANSAS THIS AFTERNOON ALONG THE SOUTHEASTWARD MOVING COLD FRONT
   ASSOCIATED WITH THE UPPER TROUGH.  THESE STORMS MAY ALSO POSE RISKS
   FOR VERY LARGE HAIL...ISOLATED TORNADOES AND DAMAGING WINDS.
   
   THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE WEATHER
   SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA WEATHER
   RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER TODAY.
