   ...SEVERE THUNDERSTORM OUTBREAK EXPECTED OVER PARTS OF THE LOWER
   MISSOURI AND MID MISSISSIPPI RIVER VALLEYS LATER TODAY AND
   TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF A FEW STRONG...LONG-TRACK TORNADOES OVER PARTS OF THE
   LOWER MISSOURI AND MID MISSISSIPPI RIVER VALLEYS LATER TODAY AND
   TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          FAR SOUTHERN IOWA
          WEST CENTRAL ILLINOIS
          MISSOURI
   
   SURROUNDING THE HIGH RISK AREA...THERE IS A MODERATE RISK OF SEVERE
   THUNDERSTORMS FROM EASTERN OKLAHOMA AND KANSAS INTO THE MID SOUTH
   AND OHIO RIVER VALLEY.
   
   A VOLATILE SITUATION IS EXPECTED TO UNFOLD OVER EASTERN PORTIONS OF
   THE CENTRAL PLAINS AND MUCH OF THE LOWER MISSOURI...MID MISSISSIPPI
   AND OHIO RIVER VALLEYS TODAY AND TONIGHT.  A VERY STRONG UPPER LEVEL
   STORM SYSTEM AND ASSOCIATED JET MAX WILL QUICKLY OVERSPREAD AN
   UNSEASONABLY WARM AND MOIST SURFACE AIR MASS THIS AFTERNOON.  WE
   EXPECT THAT SEVERAL AREAS OF SIGNIFICANT SEVERE WEATHER WILL DEVELOP
   DURING THE PERIOD.  THE MOST SIGNIFICANT OF WHICH MAY OCCUR OVER THE
   NORTHERN HALF OF MISSOURI/FAR SOUTHERN IOWA INTO WEST CENTRAL
   ILLINOIS AHEAD OF A STRENGTHENING LOW PRESSURE CENTER AND ITS
   ACCOMPANYING WARM FRONT.  THIS ACTIVITY IS EXPECTED TO DEVELOP
   DURING THE EARLY TO MID AFTERNOON AND RACE EAST-NORTHEASTWARDS
   THROUGH THE EVENING IN THE FORM OF TORNADIC SUPERCELLS...MANY OF
   WHICH COULD BECOME QUITE STRONG AND LONG-LIVED.  OTHER POTENTIALLY
   TORNADIC SUPERCELLS ARE EXPECTED TO DEVELOP LATE TODAY AND THIS
   EVENING ALONG A DRY LINE EXTENDING INTO FAR EASTERN OKLAHOMA AND
   NORTHEASTERN TEXAS.  THESE WILL SPREAD A THREAT OF SEVERE
   WEATHER...INCLUDING DAMAGING TORNADOES...ACROSS ARKANSAS INTO THE
   MID SOUTH/LOWER OHIO RIVER VALLEY THROUGH THE NIGHT.
   
   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.
