   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 541
   CONTINUES.
   
   FORCING FOR ASCENT ATTENDANT TO A SHORTWAVE TROUGH MOVING EWD ACROSS
   NEB AND SECOND IMPULSE TRACKING ENEWD ACROSS NRN CO WILL SUPPORT
   ADDITIONAL TSTM DEVELOPMENT FROM NERN CO INTO SWRN/CENTRAL NEB WHERE
   AIR MASS REMAINS MODERATELY UNSTABLE.  EFFECTIVE BULK SHEAR 30-40 KT
   WILL SUPPORT STORM ORGANIZATION WITH HAIL AND STRONG WIND GUSTS THE
   PRIMARY THREATS.
   
   RECENT STORM DEVELOPMENT OVER THE SRN PART OF THE NEB PANHANDLE HAS
   GENERALLY BEEN WEAK...BUT GREATER INSTABILITY LOCATED EWD INTO SWRN
   NEB SUGGESTS THIS ACTIVITY MAY INCREASE IN INTENSITY.  OTHERWISE...
   NWRN PART OF NEB PANHANDLE CAN BE CANCELLED EARLY FROM WW 541 WHERE
   BOUNDARY LAYER IS STABILIZING.
