   VALID 261503Z - 261700Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 105
   CONTINUES.

   SUMMARY...A SEVERE THREAT WILL CONTINUE ACRO0SS PARTS OF CNTRL MO
   LATE THIS MORNING MOVING INTO ERN MO AND WRN IL BY EARLY AFTERNOON.
   WIND DAMAGE AND HAIL WILL BE THE PRIMARY THREATS. A NEW WW FOR EARLY
   THIS AFTERNOON WILL NEED TO BE CONSIDERED TO THE EAST OF THE CURRENT
   WATCH.

   DISCUSSION...LATEST RADAR TRENDS SHOW AN MCS EXTENDING FROM SRN IA
   SWD INTO CNTRL MO WITH A SHORT BOWING LINE SEGMENT JUST TO THE EAST
   OF THE KANSAS CITY METRO. THE LINE SEGMENT IS LOCATED ALONG THE NERN
   EDGE OF MODERATE INSTABILITY NEAR A QUASI-STATIONARY FRONTAL
   BOUNDARY EXTENDING EAST TO WEST ACROSS NCNTRL MO. A MOIST AIRMASS
   SOUTH OF THE BOUNDARY EXTENDS EWD INTO SW IL WITH SFC DEWPOINTS IN
   THE MID 60S F. THIS ALONG WITH MODERATE DEEP-LAYER SHEAR EVIDENT ON
   THE ST LOUIS AND KANSAS CITY WSR-88D VWPS SHOULD HELP MAINTAIN THE
   MCS FOR SEVERAL MORE HOURS. THE LATEST HRRR SUGGESTS THAT THE LINE
   WILL MAINTAIN A BOWING STRUCTURE AND APPROACH THE ST LOUIS AREA IN
   THE 19 TO 21Z TIMEFRAME. A NEW WW WILL LIKELY NEED TO BE CONSIDERED
   AS THE LINE MOVES TOWARD THE EDGE OF WW 105.
