   AREAS AFFECTED...N-CNTRL NEB THROUGH W-CNTRL AND CNTRL SD
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 552...
   
   VALID 260427Z - 260530Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 552
   CONTINUES.
   
   SEVERE THREAT WILL PERSIST FROM W-CNTRL THROUGH CNTRL SD NEXT COUPLE
   OF HOURS WITH A MORE MARGINAL THREAT FARTHER SOUTH INTO NRN NEB.
   OVERALL TREND HAS BEEN FOR STORMS TO BECOME LESS ORGANIZED.
   HOWEVER...AT LEAST A MODEST SEVERE THREAT COULD SPREAD NEWD INTO
   N-CNTRL SD WHERE IF NECESSARY A FEW COUNTIES COULD BE ADDED TO WW
   552.
   
   STORMS CONTINUE NEWD THROUGH WRN SD AND APPEAR TO BE PROPAGATING
   ALONG CONVECTIVE OUTFLOW BOUNDARY. SOME ORGANIZED STRUCTURES WERE
   OBSERVED EARLIER...BUT OVERALL TREND HAS BEEN FOR ACTIVITY TO
   WEAKEN. DESPITE STRENGTHENING LLJ...PRIMARY LIMITING FACTOR IS A
   STABILIZING BOUNDARY LAYER AND INCREASING CONVECTIVE INHIBITION.
   NEVERTHELESS...ISOLATED STRONG TO DAMAGING WIND GUSTS REMAIN
   POSSIBLE AS ACTIVITY DEVELOPS NEWD. A FEW STORMS ARE ALSO TRYING TO
   DEVELOP ALONG COLD FRONT OVER NWRN SD...AND IF THESE STORMS
   MATURE...POTENTIAL WILL EXIST FOR A FEW CELL MERGERS. 
   
   FARTHER SOUTH ACROSS NRN NEB...STORMS ARE POORLY ORGANIZED...AND 
   PRIMARY STORM DEVELOPMENT WILL LIKELY REMAIN ON COOL SIDE OF SWD
   SURGING CONVECTIVE OUTFLOW BOUNDARY DUE TO A STRONGER CAP.
