   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 360
   CONTINUES.

   SUMMARY...EARLIER EXTENSIVE/WIDESPREAD THUNDERSTORM DEVELOPMENT
   ACROSS MUCH OF WATCH 360...FROM SERN WY ACROSS NEB PANHANDLE AND ERN
   CO...HAS EFFECTIVELY STABILIZED MOST AREAS. EXPECT THIS WATCH TO BE
   CANCELED/CLEARED IN MOST AREAS PRIOR TO SCHEDULED EXPIRATION AT 0100
   UTC/7PM MDT.

   DISCUSSION...WIDESPREAD AND ROBUST THUNDERSTORM DEVELOPMENT FROM THE
   FRONT RANGE EASTWARD WAS AIDED BY THE PASSAGE OF A COMPACT MID/UPPER
   LEVEL TROUGH DURING THE LATE AFTERNOON. THIS CONVECTION HAS
   EFFECTIVELY OVERTURNED AND STABILIZED THE AIRMASS ACROSS SERN WY AND
   MUCH OF ERN CO WITH RAIN-COOLED OUTFLOW NOW SPREADING SOUTH OF THE
   WATCH AREA AND INTO PUEBLO/OTERO COUNTIES IN CO. WITH THE POSSIBLE
   EXCEPTION OF A SMALL AREA OF NERN CO...FROM LOGAN TO
   PHILLIPS/SEDGWICK COUNTIES WHERE RESIDUAL STRONGER INSTABILITY
   REMAINS THAT COULD STILL SUPPORT POTENT STORMS WITH ISOLATED
   DOWNBURST WINDS AND LARGE HAIL...THE SEVERE WEATHER THREAT HAS
   DIMINISHED ACROSS THE BULK OF WATCH 360.
