   AREAS AFFECTED...NERN KS
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 160549Z - 160745Z
   
   NERN KS IS BEING MONITORED FOR POTENTIAL THREAT OF ISOLATED
   DAMAGING WIND GUSTS. 
   
   SATELLITE DATA SHOW A MID LEVEL DRY SURGE ASSOCIATED WITH A
   STRONG 100+ KT MID/UPPER JET SPREADING NEWD THROUGH S CNTRL KS.
   THE STRONG PRESSURE FALLS ACROSS CNTRL KS APPEAR TO BE ASSOCIATED
   WITH STRONG FORCING IN THE EXIT REGION OF THE UPPER JET. THIS JET
   AND ITS ATTENDANT LOW LEVEL JET WILL CONTINUE TO SHIFT NEWD
   TOWARD NERN KS TONIGHT. FORCING ASSOCIATED WITH THESE JETS MAY
   SUPPORT CONVECTION DEVELOPING INTO NERN KS TONIGHT. INSTABILITY
   IS VERY LIMITED IN NERN KS. HOWEVER...STRENGTH OF FLOW
   ACCOMPANYING THE JETS MAY SUPPORT LINES OF FORCED LOW TOPPED
   CONVECTION.
