   1143 AM CDT THU MAY 22 2008
   
   ...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 TORNADOES...LARGE HAIL AND DAMAGING WINDS OVER PARTS
   OF THE CENTRAL PLAINS THIS AFTERNOON AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          NORTHEAST COLORADO
          WESTERN AND CENTRAL KANSAS
          SOUTHWESTERN NEBRASKA
          FAR NORTHWESTERN OKLAHOMA
   
   ELSEWHERE...SEVERE STORMS ARE POSSIBLE OVER SOUTHEASTERN WYOMING AND
   MUCH OF WESTERN AND CENTRAL NEBRASKA SOUTHWARD INTO WESTERN
   OKLAHOMA/THE FAR EASTERN TEXAS PANHANDLE.
   
   AN INTENSE UPPER LEVEL LOW PRESSURE SYSTEM WILL REMAIN IN PLACE OVER
   THE GREAT BASIN TODAY...WHICH WILL INCREASE WINDS ALOFT OVER THE
   CENTRAL AND SOUTHERN HIGH PLAINS.  A VERY WARM AND HUMID SURFACE AIR
   MASS IS ALREADY OVERSPREADING MUCH OF OKLAHOMA AND KANSAS...AND THE
   MOIST AIR WILL CONTINUE NORTHWARD INTO THE CENTRAL PLAINS TODAY. 
   THIS WILL RESULT IN A VERY UNSTABLE AIR MASS EAST OF A SURFACE DRY
   LINE WHICH WILL BECOME ESTABLISHED NORTH TO SOUTH ACROSS THE HIGH
   PLAINS.  CONDITIONS APPEAR RIPE FOR VERY INTENSE THUNDERSTORMS THIS
   AFTERNOON OVER THIS REGION...WITH WIND CHANGES WITH HEIGHT FAVORING
   THE DEVELOPMENT OF SUPERCELLS AND TORNADOES INTO THE EARLY EVENING. 
   VERY LARGE HAIL AND ISOLATED DAMAGING WINDS ARE ALSO EXPECTED TO
   ACCOMPANY THE MORE INTENSE STORMS.  THUNDERSTORMS WILL CONTINUE
   OVERNIGHT OVER THE CENTRAL PLAINS...WITH CONTINUED THREAT OF LARGE
   HAIL.
   
   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.
