   PUBLIC SEVERE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1136 AM CDT WED MAY 13 2009
   
   ...SEVERE THUNDERSTORMS EXPECTED FROM THE CENTRAL/SOUTHERN PLAINS TO
   THE MID MISSISSIPPI VALLEY LATER TODAY AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS FROM THE
   CENTRAL/SOUTHERN PLAINS TO THE MID MISSISSIPPI VALLEY LATER TODAY
   AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          NORTHWEST ARKANSAS
          ILLINOIS
          SOUTHEAST KANSAS
          MISSOURI
          OKLAHOMA
   
   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM NORTH TEXAS TO THE
   GREAT LAKES.
   
   SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON ALONG A
   SHARP COLD FRONT THAT WILL SURGE SOUTHEASTWARD ACROSS THE CENTRAL
   PLAINS INTO THE MID MISSISSIPPI VALLEY.  THUNDERSTORMS ARE EXPECTED
   TO INTENSIFY DURING THE HEAT OF THE DAY AS A VERY MOIST LOW LEVEL
   AIRMASS SURGES INTO AN INCREASINGLY CONVERGENT FRONTAL
   ZONE...INITIALLY ACROSS PARTS OF SOUTHEAST IA AND WEST CENTRAL
   ILLINOIS...THEN DEVELOPING SOUTHWESTWARD ACROSS MISSOURI INTO KANSAS
   BY LATE AFTERNOON.  THIS ACTIVITY WILL SPREAD SOUTHWARD INTO
   OKLAHOMA AND ARKANSAS LATER THIS EVENING.  VERY LARGE HAIL AND
   DAMAGING WINDS ARE LIKELY WITH MANY STORMS...ALONG WITH A FEW
   TORNADOES.
   
   ADDITIONALLY...A MID LEVEL CIRCULATION LOCATED IN SOUTHWESTERN
   MISSOURI WILL MOVE ACROSS SOUTHERN MISSOURI THIS AFTERNOON.  THIS
   FEATURE WILL LIKELY ENHANCE SEVERE POTENTIAL DOWNSTREAM ACROSS PARTS
   OF EASTERN/SOUTHERN MISSOURI INTO SOUTHERN ILLINOIS.  WIND/MOISTURE
   PROFILES WITH THIS CIRCULATION SUGGEST THE POSSIBILITY OF A STRONG
   TORNADO OR TWO WITH SUPERCELLS THAT EVOLVE ACROSS THIS REGION. IN
   ADDITION...LARGE HAIL AND DAMAGING WINDS SHOULD ALSO BE ANTICIPATED
   WITH THESE STORMS.
   
   STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
   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.
