   ...OUTBREAK OF SEVERE THUNDERSTORMS INCLUDING A FEW
   VIOLENT....LONG-TRACK TORNADOES OVER PARTS OF THE LOWER MISSOURI
   VALLEY TODAY THROUGH TONIGHT.
   
   THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
   DEVELOPMENT OF A FEW VIOLENT....LONG-TRACK TORNADOES OVER PARTS OF
   THE LOWER MISSOURI VALLEY LATER TODAY THROUGH TONIGHT.
   
   THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE
   
          SOUTHERN IOWA
          WESTERN ILLINOIS
          NORTHEAST KANSAS
          NORTHERN MISSOURI
          SOUTHEAST NEBRASKA
   
   OTHER SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS AREAS SURROUNDING
   THE HIGH RISK.
   
   AN OUTBREAK OF SEVERE STORMS AND TORNADOES IS EXPECTED ACROSS PARTS
   OF THE CENTRAL PLAINS AND LOWER MISSOURI VALLEY THROUGH TONIGHT.
   
   STRONG LOW PRESSURE SYSTEM NOW LOCATED OVER NORTH CENTRAL KANSAS
   WILL MOVE EASTWARD INTO NORTHEAST AND EAST CENTRAL KANSAS TONIGHT. 
   STRONG DRYLINE EXTENDS FROM THE LOW SOUTHWARD INTO SOUTH CENTRAL
   KANSAS AND SOUTHWEST OKLAHOMA. ALSO...A WARM FRONT EXTENDS
   NORTHEAST FROM THE LOW INTO SOUTHEAST NEBRASKA THEN SOUTHEAST
   THROUGH CENTRAL MISSOURI AND EXTREME SOUTHERN ILLINOIS.  LOW LEVEL
   WINDS NEAR 50 KT EXTEND NWD FROM EASTERN OKLAHOMA INTO WESTERN IOWA
   BRINGING VERY WARM AND HUMID CONDITIONS TO THE REGION EAST OF THE
   LOW/DRYLINE.  THE MIDDLE AND UPPER LEVEL JET STREAM EXTENDS FROM
   CENTRAL NEW MEXICO EASTWARD OVER NORTH CENTRAL OKLAHOMA PROVIDING
   FAVORABLE COUPLING OF LOW/MIDDLE LEVEL WINDS CREATING FAVORABLE AND
   STRONG VERTICAL SHEAR. THIS COMBINED WITH WARM...HUMID UNSTABLE AIR
   IS VERY FAVORABLE FOR LARGE AND DAMAGING TORNADOES IN THE HIGH RISK
   AREA.
   
   AS THE LOW MOVES INTO NORTHEAST AND EAST CENTRAL KANSAS THIS
   EVENING...THE DRYLINE IS FORECAST TO PUSH EAST AND NORTHEAST INTO
   EASTERN KANSAS AND WESTERN MISSOURI INCREASING SUPERCELL ACTIVITY
   INTO NORTHWEST AND WEST CENTRAL MISSOURI.  ALSO...LOW LEVEL JET WILL
   MOVE INTO WESTERN AND NORTH CENTRAL MISSOURI AND INCREASE ACTIVITY
   ACROSS NORTHERN MISSOURI AND SOUTHERN IOWA TONIGHT.
   
   THIS IS A PARTICULARLY DANGEROUS SITUATION.  THOSE IN THE THREATENED
   AREA ARE URGED TO REVIEW TORNADO SAFETY RULES AND MONITOR THE LATEST
   INFORMATION ON NOAA WEATHER RADIO FOR FURTHER WATCHES...WARNINGS AND
   STATEMENTS.
   
   ACCOMPANYING THE ACTIVITY ACROSS CENTRAL MISSOURI INTO WEST CENTRAL
   ILLINOIS...STRONG DAMAGING WINDS ARE EXPECTED THROUGH TONIGHT.
   
   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.
