   AREAS AFFECTED...SWRN NEB
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 152308Z - 160045Z
   
   POTENTIAL FOR DAMAGING WINDS/LARGE HAIL IS EXPECTED TO PERSIST FOR
   THE NEXT SEVERAL HOURS AND A WW MAY BE REQUIRED.
   
   AS OF 2252Z...NORTH PLATTE RADAR IMAGERY SHOWS INTENSE LINE OF
   STORMS OVER SRN CUSTER COUNTY WWD INTO CNTRL PORTIONS OF LINCOLN
   COUNTY. EMBEDDED WITHIN THIS SHORT LINE WAS A SUPERCELL OVER S-CNTRL
   CUSTER COUNTY /S OF BBW/. LATEST OBJECTIVE ANALYSIS SUGGESTS THAT
   THIS LINE OF STORMS IS MOVING/DEVELOPING SWD THROUGH AXIS OF
   STRONGEST INSTABILITY WHERE MLCAPES HAVE INCREASED TO AROUND 4000
   J/KG.
   
   THOUGH RED WILLOW NEB PROFILER SHOWS COMPARATIVELY WEAKER MID-LEVEL
   FLOW THAN PROFILER SITES OVER ERN NEB...DEGREE OF INSTABILITY WILL
   SUPPORT ORGANIZED SEVERE STORMS CAPABLE OF DAMAGING WINDS/HAIL.
   STORMS SHOULD CONTINUE TO PROPAGATE SWD TOWARD THE KS BORDER WITH
   SOME ADDITIONAL WWD DEVELOPMENT STILL POSSIBLE.
   
   EITHER AN ADDITIONAL WW OR REPLACEMENT WW MAY BE REQUIRED WITHIN THE
   HOUR.
