   SYSTEM EXTENDING FROM CALDWELL COUNTY MO SWWD TO THE BOW APEX IN
   JOHNSON COUNTY KS AND THEN NWWD TO POTTAWATOMIE COUNTY KS...WITH
   THIS BOW MOVING SSEWD AT 35 KT.  RECENT REPORTS HAVE INDICATED
   SEVERE WIND GUSTS FROM TOP THROUGH THE KANSAS CITY METRO AREA
   INCLUDING DAMAGING WIND GUSTS AND HAIL AROUND 1 INCH IN DIAMETER.
   
   IR SATELLITE IMAGERY INDICATED CLOUD TOPS REMAIN COLD WITH NO SIGN
   OF WARMING.  MEANWHILE...A 40 KT SWLY LLJ PER TOP WSR-88D VAD IS
   RESULTING IN STRONG LOW LEVEL WAA INTO NERN KS/NWRN MO WHICH WILL
   CONTINUE TO SUPPORT NEW TSTM DEVELOPMENT.  VEERING OF THE LLJ
   OVERNIGHT SUGGESTS THIS FORWARD PROPAGATING MCS WILL CONTINUE TO
   TRACK SWD INTO A MODERATELY UNSTABLE AIR MASS.
