   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1119 AM CDT MON MAR 23 2009
   
   ...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CENTRAL AND
   SOUTHERN PLAINS...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS OVER PARTS
   OF THE CENTRAL AND SOUTHERN PLAINS THIS AFTERNOON THROUGH TONIGHT. A
   SECONDARY AREA OF POTENTIAL WILL BE OVER CNTRL AND NERN NEBRASKA.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          CENTRAL AND EASTERN KANSAS
          NORTHERN OKLAHOMA
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM THE RED RIVER
   VALLEY REGION OF TEXAS AND OKLAHOMA NORTH/NORTHEAST INTO PARTS OF
   NEBRASKA...MISSOURI...IOWA...SOUTH DAKOTA...AND SOUTHWEST MINNESOTA.
   
   A STRONG UPPER TROUGH WILL SWEEP EAST-NORTHEAST FROM THE FOUR
   CORNERS REGION ACROSS THE SOUTHERN PLAINS AND LOWER MISSOURI VALLEY
   LATER TODAY THROUGH EARLY TUESDAY.  AS THIS OCCURS...A STRONG
   SURFACE LOW NOW IN WESTERN NEBRASKA WILL TRACK NORTHEAST INTO
   EASTERN SOUTH DAKOTA.
   
   A COLD FRONT AND PRE-FRONTAL TROUGH ASSOCIATED WITH THE LOW WILL
   SERVE AS A FOCUS FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND
   TONIGHT AS THE FRONT AND TROUGH PROGRESS EAST-SOUTHEAST ACROSS THE
   CENTRAL AND SOUTHERN PLAINS.
   
   THE AMOUNT OF MOISTURE AVAILABLE TO STORMS WILL BE MARGINAL COMPARED
   TO SOME HIGHER END SEVERE WEATHER EVENTS. HOWEVER...VERY STRONG WIND
   SHEAR WILL BE FAVORABLE FOR LONG-LIVED...ROTATING STORMS/SUPERCELLS.
   SHOULD SUPERCELLS FORM...THEY WILL HAVE THE POTENTIAL TO PRODUCE A
   FEW STRONG TORNADOES...IN ADDITION TO SEVERE HAIL AND WIND.
   
   ANOTHER AREA OF CONCERN...ALTHOUGH NOT IN THE MODERATE RISK
   AREA...WILL BE OVER CENTRAL AND EASTERN NEBRASKA. THIS AREA WILL
   ALSO HAVE WINDS FAVORABLE FOR STORM ROTATION AND POSSIBLE
   TORNADOES...ALONG AND AHEAD OF THE SURFACE LOW TRACK.
   
   ALTHOUGH ISOLATED SEVERE STORMS MAY OCCUR ANYTIME BETWEEN NOW AND
   SUNRISE TUESDAY IN THE HIGHLIGHTED REGION...THE BULK OF THE SEVERE
   WEATHER IS EXPECTED LATE THIS AFTERNOON THROUGH LATE THIS EVENING.
   
   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.
   ADDITIONALLY...STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING
   THIS DEVELOPING SITUATION.
