   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 335
   CONTINUES.
   
   A LARGE CLUSTER OF THUNDERSTORMS ONGOING IN CNTRL NEB WILL GRADUALLY
   MOVE SEWD ACROSS SRN NEB WITH LARGE HAIL AND WIND DAMAGE LIKELY WITH
   THE STRONGER CELLS. AN ISOLATED TORNADO THREAT MAY ALSO EXIST WITH
   THE MORE WELL-STRUCTURED SUPERCELLS. A WW SHOULD BECOME NECESSARY
   SOUTHEAST OF WW 335 OVER THE NEXT HOUR OR SO.
   
   AN MCS IS CURRENTLY LOCATED NEAR A COLD FRONT EXTENDING FROM CNTRL
   NEB EWD INTO SW IA. MODERATE INSTABILITY IS STILL PRESENT SOUTH OF
   THE BOUNDARY ACCORDING TO RUC ANALYSIS SUGGESTING THE ACTIVITY
   SHOULD PERSIST FOR SEVERAL MORE HOURS. STRONG VERTICAL SHEAR AND
   STEEP MID-LEVEL LAPSE RATES WILL CONTINUE TO SUPPORT SUPERCELLS
   CAPABLE OF LARGE HAIL. WIND DAMAGE WILL ALSO BE POSSIBLE ESPECIALLY
   AS THE STORMS MOVE SEWD INTO INCREASING LOW-LEVEL MOISTURE. THE
   INTENSE STORM IN THE SERN PART OF WW 335 WILL LIKELY CONTINUE ACROSS
   SE NEB AND MAY REACH PARTS OF NE KS LATER TONIGHT.
