   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 30
   CONTINUES.

   SUMMARY...SUPERCELLS CAPABLE OF VERY LARGE HAIL...ISOLATED TORNADOES
   AND DAMAGING WINDS WILL PERSIST ACROSS THE WATCH AREA THIS EVENING.

   DISCUSSION...MULTIPLE SLOW-MOVING SUPERCELLS PERSIST FROM SERN KS
   INTO WRN MO THIS EVENING WITHIN AN EXTREMELY UNSTABLE AIR MASS. ONE
   CELL OVER BATES COUNTY MO APPEARS TO HAVE PRODUCED A BRIEF TORNADO
   RECENTLY. 

   AREA VWPS INDICATE A STRENGTHENED LOW-LEVEL JET WHICH HAS INCREASED
   LOW-LEVEL SHEAR AVAILABLE TO THESE CELLS. MID TO UPPER LEVEL FLOW IS
   MARGINAL...THUS THE SLOW-MOVING HP NATURE. AS SUCH...THESE STORMS
   ARE EXPECTED TO LARGELY REMAIN WITHIN THE CONFINES OF WW 30. 

   AN ISOLATED LEFT-MOVING CELL IS MOVING OUT OF THE WATCH AND OTHER
   ISOLATED ELEVATED CELLS ARE NOW FORMING OVER SERN IA. ANY OF THESE
   STORMS WILL HAVE HAIL POTENTIAL...BUT AN ADDITIONAL WATCH MAY NOT BE
   REQUIRED.
