   VALID 270427Z - 270600Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 690
   CONTINUES.
   
   BUT THE SEVERE THREAT APPEARS TO BE DIMINISHING...AND A NEW WW IS
   NOT ANTICIPATED AT THE 06Z EXPIRATION OF WW 690.
   
   NOTABLE WEAKENING TRENDS IN THE ONGOING MESOSCALE CONVECTIVE SYSTEM
   APPROACHING BROKEN BOW...AND ADJACENT AREAS OF CENTRAL
   NEBRASKA...HAVE BECOME APPARENT IN LATEST SATELLITE/RADAR AND
   LIGHTNING DATA.  WHILE IT MAY STILL BE SEVERAL MORE HOURS BEFORE
   ACTIVITY COMPLETELY DISSIPATES...THERE IS LITTLE EVIDENT TO SUGGEST
   THAT SUBSTANTIVE REINTENSIFICATION WILL TAKE PLACE AS STORMS SPREAD
   EAST OF THE WATCH DURING THE 05-07Z TIME FRAME.
