   NWS STORM PREDICTION CENTER NORMAN OK

   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CENTRAL PLAINS
   THIS AFTERNOON AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF A FEW STRONG TORNADOES OVER PARTS OF THE CENTRAL
   PLAINS THIS AFTERNOON AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          WESTERN IOWA
          EASTERN HALF OF NEBRASKA
          FAR SOUTHEAST SOUTH DAKOTA
   
   ELSEWHERE...ORGANIZED SEVERE STORMS ARE ALSO POSSIBLE SURROUNDING
   THE HIGH RISK FROM WESTERN KANSAS TO SOUTHERN WI.
   
   VERY WARM...MOIST AND BUOYANT AIRMASS IS SPREADING NORTHWARD ACROSS
   THE PLAINS THIS MORNING.  THIS NORTHWARD SURGE IN INSTABILITY WILL
   CREATE A FAVORABLE ENVIRONMENT FOR ORGANIZED...POTENTIALLY
   DAMAGING...SEVERE THUNDERSTORMS LATER THIS AFTERNOON/EVENING ACROSS
   THE CENTRAL PLAINS INTO THE MID MS VALLEY REGION.
   
   MID-HIGH LEVEL JET STREAM WINDS WILL INCREASE ACROSS THE CENTRAL
   ROCKIES INTO THE CENTRAL PLAINS LATER THIS AFTERNOON...ENHANCING THE
   VERTICAL SHEAR PROFILES FOR SUPERCELL THUNDERSTORMS.  GIVEN THE
   INCREASE IN MOISTURE...ATMOSPHERIC CONDITIONS APPEAR TO BE QUITE
   FAVORABLE FOR TORNADO DEVELOPMENT LATER TODAY INTO THE EVENING HOURS
   ACROSS PORTIONS OF NEBRASKA INTO WESTERN IOWA.  IN ADDITION...VERY
   LARGE HAIL AND DAMAGING WINDS COULD ALSO ACCOMPANY SEVERE
   THUNDERSTORMS INTO THE OVERNIGHT HOURS AS ACTIVITY SPREADS TOWARD
   SRN WI.
   
   THIS IS POTENTIALLY A VERY DANGEROUS SITUATION. 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.
