   AREAS AFFECTED...SE WY...WRN-CNTRL NEB...NE CO

   CONCERNING...SEVERE THUNDERSTORM WATCH 441...

   VALID 242337Z - 250100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 441
   CONTINUES.

   SUMMARY...A SEVERE THREAT WILL LIKELY CONTINUE ACROSS WW 441 OVER
   THE NEXT FEW HOURS. WIND DAMAGE AND HAIL WILL BE THE PRIMARY
   THREATS. THE POTENTIAL FOR SEVERE STORMS SHOULD GRADUALLY SHIFT SWD
   WITH TIME.

   DISCUSSION...THE LATEST SFC ANALYSIS SHOWS AN 1009 MB LOW OVER SRN
   WY WITH DEWPOINTS IN THE MID TO UPPER 50S EXTENDING EWD FROM THE LOW
   ACROSS WRN NEB. NUMEROUS THUNDERSTORMS HAVE DEVELOPED ALONG THE
   CORRIDOR OF LOW-LEVEL MOISTURE WHERE MESOANALYSIS SHOWS MODERATE
   INSTABILITY WITH MLCAPE ESTIMATED IN THE 1500 TO 2500 J/KG RANGE. IN
   ADDITION...THE PROFILERS AT PLATTEVILLE CO AND MERRIMAN NEB SHOW 0-6
   KM SHEAR IN THE 35 TO 40 KT RANGE. THIS ENVIRONMENT SHOULD CONTINUE
   TO SUPPORT SEVERE THUNDERSTORM DEVELOPMENT FOR SEVERAL MORE HOURS
   THIS EVENING. STEEP MID-LEVEL LAPSE RATES IN PLACE ACROSS THE WRN
   PART OF THE WATCH SHOULD ENCOURAGE HAIL FORMATION WITH THE STRONGER
   CELLS. IF A COLD POOL CAN ORGANIZE AND MOVE SEWD ACROSS NERN CO OR
   SW NEB...THEN THE WIND DAMAGE THREAT COULD INCREASE AS WELL.
