   CONCERNING...SEVERE THUNDERSTORM WATCH 225...226...

   VALID 271120Z - 271245Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   225...226...CONTINUES.

   SUMMARY...AN ISOLATED THREAT FOR WIND DAMAGE AND HAIL WILL CONTINUE
   THIS MORNING. HOWEVER...THE THREATS ARE EXPECTED TO BECOME
   INCREASINGLY MARGINAL WITH TIME AND WW ISSUANCE IS NOT ANTICIPATED
   DOWNSTREAM OF THE CURRENT WATCHES.

   DISCUSSION...A MULTI-SEGMENTED LINEAR MCS IS ONGOING FROM JUST EAST
   OF DES MOINES TO JUST NORTH OF KANSAS CITY. THE SRN PART OF THE MCS
   STILL HAS A BOW-STRUCTURE. OBJECTIVE ANALYSIS SUGGESTS THE BOW IS
   LOCATED IN MODERATE INSTABILITY WHERE MUCAPE VALUES ARE 1500 TO 2000
   J/KG. THIS COMBINED WITH A LOW TO MID-LEVEL JET JUST BEHIND THE
   LINEAR MCS COULD SUPPORT AN ISOLATED WIND DAMAGE AND HAIL THREAT FOR
   A FEW MORE HOURS. HOWEVER...DEEP LAYER SHEAR BECOMES WEAK IN AREAS
   SOUTH OF KANSAS CITY SUGGESTING THE SEVERE THREAT WILL BECOME
   INCREASINGLY MARGINAL AS THE MCS MOVES SSEWD THIS MORNING.
