   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 273
   CONTINUES.
   
   STRONG THUNDERSTORMS EXTEND FROM SERN/S CENTRAL NEB SWWD INTO SWRN
   KS AHEAD OF COLD FRONT THAT EXTENDS FROM CENTRAL IA INTO N CENTRAL
   KS AND SERN CO.  AIR MASS AHEAD OF THE ACTIVITY REMAINS MODERATELY
   UNSTABLE WITH MLCAPE BETWEEN 1000-2000 J/KG.  THE LINE IS MOVING
   INTO AREA WHERE MESO ANALYSIS SHOWS WEAKER DEEP LAYER SHEAR S AND E
   OF THE LINE.  THE OUTFLOW HAS SURGED SEWD OUT AHEAD OF THE ACTIVITY
   AND THERE LOOKS TO BE A WEAKENING TREND OCCURRING WITH MUCH OF THE
   LINE...WITH THE STRONGEST ACTIVITY NOW IN JEWELL COUNTY KS AND
   THAYER COUNTY NEB.  THUS...THERE SEEMS TO BE AN ISOLATED THREAT OF
   SOME HAIL WITH THE ACTIVITY...BUT WITH THE GENERAL TREND CURRENTLY
   LOOKING LIKE MORE HEAVY PRECIPITATION WOULD NOT ANTICIPATE AN
   ADDITIONAL WATCH SOUTH AND EAST OF WW273.
