   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1153 AM CDT SAT MAY 29 2004
   
   VALID 291653Z - 300100Z
   
   ...OUTBREAK OF SEVERE THUNDERSTORMS INCLUDING A FEW
   STRONG...LONG-TRACK TORNADOES OVER PARTS OF THE SOUTHERN AND CENTRAL
   PLAINS TODAY THROUGH TONIGHT.
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF A FEW STRONG...LONG-TRACK TORNADOES OVER PARTS OF THE
   SOUTHERN AND CENTRAL PLAINS LATER TODAY THROUGH TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          WESTERN IOWA
          CENTRAL AND EASTERN KANSAS
          NORTHWEST MISSOURI
          CENTRAL AND EASTERN NEBRASKA
          OKLAHOMA
   
   THERE IS ALSO A RISK OF SEVERE THUNDERSTORMS OVER MUCH OF THE
   REMAINDER OF THE PLAINS FROM THE CANADIAN BORDER OF EASTERN ND AND
   MN SWD THRU MUCH OF CENTRAL TX.
   
   AN OUTBREAK OF SEVERE THUNDERSTORMS INCLUDING THE POSSIBILITY OF
   STRONG TORNADOES...VERY LARGE HAIL AND DAMAGING WINDS IS EXPECTED
   THIS AFTERNOON AND EARLY TONIGHT OVER A LARGE PART OF THE CENTRAL
   AND SOUTHERN PLAINS AS A VIGOROUS STORM SYSTEM DEEPENS OVER THE
   AREA.
   
   AN INTENSIFYING SURFACE LOW IN THE CENTRAL HIGH PLAINS WILL MOVE
   SLOWLY NE THROUGH EARLY SUNDAY...PRODUCING STRONG SOUTHERLY WINDS
   THAT WILL DRAW INCREASINGLY MOIST AND UNSTABLE AIR NORTH ACROSS THE
   PLAINS.  A VIGOROUS JET STREAM DISTURBANCE NOW MOVING EAST ACROSS
   THE ROCKIES WILL STRENGTHEN WINDS IN THE MID AND UPPER LEVELS OF THE
   ATMOSPHERE LATER TODAY AND TONIGHT.
   
   WITH VERY STRONG SURFACE HEATING THIS AFTERNOON...VARIOUS SURFACE
   FEATURES WILL BECOME THE FOCUS FOR RAPID SEVERE THUNDERSTORM
   DEVELOPMENT OVER PARTS OF NEBRASKA...IOWA...EASTERN SOUTH DAKOTA AND
   NORTHERN KANSAS.  OTHER STORMS MAY FORM A LITTLE LATER THIS
   AFTERNOON AND EVENING SOUTHWARD THROUGH OKLAHOMA INTO PARTS OF
   WESTERN AND NORTHERN TEXAS.
   
   THE COMBINATION OF THE VERY UNSTABLE AIR AND INCREASINGLY FAVORABLE
   WIND PROFILES WILL RESULT IN SUPERCELL THUNDERSTORMS.  CONDITIONS
   WILL SUPPORT STORMS THAT QUICKLY DEVELOP THE POTENTIAL FOR BOTH
   TORNADOES AND VERY LARGE HAIL. A STRONG POSSIBLY FOR LONG TRACK
   TORNADOES WILL EXIST IN THE HIGH RISK AREA.  
   
   THE SEVERE THREAT WILL LIKELY CONTINUE WELL AFTER DARK AND SPREAD
   EAST ACROSS REMAINING PORTIONS OF IOWA...MISSOURI AND OKLAHOMA.  IN
   ADDITION...MORE ISOLATED BUT STILL POTENTIALLY TORNADIC SUPERCELLS
   ARE POSSIBLE IN REGIONS ADJACENT TO THE HIGH RISK AREA FROM
   SOUTHWEST MINNESOTA SOUTH TO THE BIG BEND REGION OF TEXAS.
   
   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.
