   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   540...541...CONTINUES.
   
   REGIONAL RADARS INDICATED THE STRONGEST STORM WITHIN WW/S 540/541
   MOVED INTO THE WRN PORTION OF 540 /KIT CARSON AND CHEYENNE COUNTIES
   CO AT 02Z/...WITH THIS STORM TRACKING EWD AT 25 KT.  A CORRIDOR OF
   MODERATE INSTABILITY EXTENDS ENEWD FROM EAST CENTRAL CO INTO NW/NRN
   KS AND SRN NEB.  THIS INSTABILITY AND EFFECTIVE BULK SHEAR AROUND 35
   KT SHOULD SUPPORT ADDITIONAL ISOLATED STORMS...BUT OVERALL THREAT
   FOR WIDESPREAD SEVERE STORMS APPEARS TO BE DIMINISHING AS SURFACE
   BASED INHIBITION INCREASES WITH FURTHER NOCTURNAL COOLING.
   
   WEAKENING INSTABILITY ACROSS NERN CO /NORTH OF THE KIT CARSON/
   CHEYENNE COUNTIES STORM/ SHOULD CONTINUE TO LIMIT THE THREAT FOR
   ADDITIONAL SEVERE STORMS WITHIN WW 541 ALLOWING THIS WATCH TO EXPIRE
   AS SCHEDULED AT 03Z...WHILE PARTS OF WW 540 MAY BE CANCELLED EARLY
   WITH THE SERN EXTENT EXTENDED IN AREA OVER CENTRAL KS.
