   AREAS AFFECTED...ERN NEB
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 270433Z - 270530Z
   
   STORMS WILL MOVE EAST OF WW 562 BY 05Z WHERE A THREAT FOR ISOLATED
   DAMAGING WIND AND HAIL COULD PERSIST INTO A PORTION OF ERN NEB. IT
   REMAINS UNCLEAR WHETHER COVERAGE AND MAGNITUDE OF THREAT WARRANT
   ANOTHER WW ISSUANCE...BUT AREA WILL CONTINUE TO BE MONITORED.
   
   BOWING SEGMENT ALONG NRN END OF A LINE OF WEAKER STORMS IS MOVING
   EWD THROUGH N-CNTRL NEB AT 40 KT. ACTIVITY WILL REMAIN WITHIN ZONE
   OF ISENTROPIC ASCENT NORTH OF OUTFLOW BOUNDARY AS SHORTWAVE TROUGH
   ADVANCES THROUGH THE CNTRL AND NRN HIGH PLAINS. LATEST OBJECTIVE
   ANALYSIS INDICATES THE ATMOSPHERE OVER ERN NEB REMAINS MODERATELY
   UNSTABLE WITH 1500-2000 J/KG MUCAPE ABOVE THE STABLE SURFACE LAYER.
   BACKGROUND ASCENT ASSOCIATED WITH EWD ADVANCING SHORTWAVE TROUGH AND
   40-50 KT EFFECTIVE SHEAR SUGGEST THE STORMS COULD CONTINUE A WHILE
   LONGER. HOWEVER...UNLESS MORE STORMS BEGIN TO INTENSIFY ON SRN
   FLANK...COVERAGE OF SEVERE EVENTS MIGHT NOT BE SUFFICIENT FOR
   ANOTHER WW.
