   PLATEAU INTO MID-SOUTH/LOWER OHIO VALLEY LATER TODAY AND TONIGHT...
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OKLAHOMA IS FORECASTING
   THE DEVELOPMENT OF A FEW STRONG TORNADOES AND POTENTIALLY WIDESPREAD
   DAMAGING WINDS OVER PARTS OF THE OZARK PLATEAU INTO MID-SOUTH/LOWER
   OHIO VALLEY LATER TODAY AND TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          MUCH OF ARKANSAS
          SOUTHERN ILLINOIS
          FAR SOUTHWEST INDIANA
          WESTERN KENTUCKY

   ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM PORTIONS OF THE
   CENTRAL AND SOUTHERN PLAINS EAST/NORTHEAST THROUGH THE MID
   MISSISSIPPI/OHIO VALLEYS AND MID-SOUTH.
   
   A POWERFUL UPPER-LEVEL STORM SYSTEM AND ASSOCIATED 100+ MPH JET
   STREAM OVER THE SOUTHWESTERN DESERTS THIS MORNING WILL PROGRESS EAST
   THROUGH THE SOUTHERN ROCKIES...CENTRAL AND SOUTHERN PLAINS...
   REACHING THE MIDDLE AND LOWER MISSISSIPPI VALLEY BY MONDAY MORNING. 
   MEANWHILE...AN AREA OF LOW PRESSURE IN THE LOWER ATMOSPHERE FORMING
   OVER SOUTHEAST COLORADO WILL MOVE EAST ACROSS SOUTHERN KANSAS OR
   NORTHERN OKLAHOMA BEFORE ACCELERATING NORTHEAST THROUGH CENTRAL
   MISSOURI AND THE OHIO VALLEY TONIGHT.  SOUTHERLY WINDS IN ADVANCE OF
   THIS LOW PRESSURE WILL DRAW A WARM AND HUMID AIR MASS NORTH THROUGH
   THE CENTRAL AND SOUTHERN PLAINS...MIDDLE/LOWER MISSISSIPPI AND OH
   VALLEYS.
   
   INITIAL SEVERE THUNDERSTORM DEVELOPMENT IS EXPECTED THIS AFTERNOON
   INTO EVENING OVER PORTIONS OF EASTERN KANSAS INTO WESTERN MISSOURI

   THE DEVELOPMENT OF INTENSE STORMS CAPABLE OF LARGE HAIL...DAMAGING
   WINDS AND A FEW TORNADOES.  THIS ACTIVITY IS EXPECTED TO RAPIDLY
   MOVE AND/OR DEVELOP EAST AND NORTHEAST THROUGH THE MID MISSISSIPPI
   AND OHIO VALLEYS TONIGHT IN CONJUNCTION WITH THE SURFACE LOW
   PRESSURE CENTER.

   EVENING INTO TONIGHT FROM THE VICINITY OF A PACIFIC FRONT/DRYLINE
   OVER EASTERN OKLAHOMA AND WESTERN ARKANSAS NORTHEAST TOWARD THE
   CONFLUENCE OF THE MISSISSIPPI AND OHIO RIVERS.  THESE STORMS WILL
   MOVE EAST THROUGH THE EARLY MORNING HOURS MONDAY WITH A RISK FOR
   POTENTIALLY WIDESPREAD DAMAGING WINDS AND TORNADOES /SOME POSSIBLY
   STRONG/ FROM THE OZARK PLATEAU ACROSS PARTS OF THE MID-SOUTH.
