   AREAS AFFECTED...MUCH OF THE CNTRL PLAINS AND MID/LWR MO VALLEY
   REGION
   
   CONCERNING...TORNADO WATCH 424...426...
   
   VALID 160033Z - 160200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 424...426...CONTINUES.
   
   TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE THREAT AND THE
   POSSIBILITY OF ADDITIONAL WWS ACROSS THE LOWER AND MID MISSOURI
   VALLEY THIS EVENING.
   
   A CLUSTER OF STORMS HAS EVOLVED WITHIN THE STRONGLY UNSTABLE WARM
   SECTOR AIR MASS ACROSS CENTRAL KANSAS...WHERE COLD POOLS HAVE BEEN
   CONSOLIDATING...AND MAY BEGIN TO ACCELERATE EASTWARD WITHIN A 30+ KT
   DEEP LAYER MEAN SOUTHWESTERLY FLOW.  THIS ACTIVITY...AND MORE
   DISTINCT SUPERCELLS WITHIN DOWNSTREAM WARM ADVECTION REGION MAY
   ADVANCE INTO THE KANSAS CITY AND ADJACENT KANSAS/MISSOURI BORDER
   AREA DURING THE 03-05Z TIME FRAME.  HOWEVER...IT SEEMS AT LEAST A
   BIT MORE PROBABLE THAT INCREASING INHIBITION WITH THE ONSET OF
   DIURNAL WARM SECTOR COOLING COULD CONTRIBUTE TO WEAKENING OF THIS
   ACTIVITY...WITH PRIMARY CONVECTIVE DEVELOPMENT OCCURRING TO THE
   NORTH OF THE FRONT NEAR THE KANSAS/NEBRASKA BORDER AREA. 
   REGARDLESS...IN THE PRESENCE OF MODERATE TO  STRONG INSTABILITY AND
   STRONG DEEP LAYER SHEAR...ADDITIONAL WWS APPEAR LIKELY TO BE NEEDED
   ACROSS PARTS OF SOUTHEAST NEBRASKA/WEST CENTRAL AND NORTHWEST
   MISSOURI...AND SOUTHWEST IOWA BY THE 03-05Z TIME FRAME.
