.DISCUSSION...
THUNDERSTORMS ARE DYING DOWN THIS EVENING AS UPPER LEVEL SUPPORT
AND HEATING OF THE DAY HAS FINISHED. REMAINS OF EARLIER
THUNDERSTORM CURRENTLY MOVING OVER BURN SITE MAY CAUSE THE
OCCASIONAL GUSTY WIND BEFORE MIDNIGHT.  DEEP UPPER LEVEL TROUGH
WILL PERSIST OVER COLORADO TOMORROW BRINGING PARTLY CLOUDY SKIES
TO ALL AREAS. SMALL UPPER LEVEL DISTURBANCES WILL CONTINUE TO MOVE
OVER AREA AND KICK OFF SOME ISOLATED AFTERNOON SHOWERS AND
THUNDERSTORMS. MAIN CONCERN WITH ANY THUNDERSTORMS WILL BE GUSTY
WINDS AT THE SURFACE. MOST THUNDERSTORMS WILL DIE DOWN AFTER
SUNSET THOUGH THE OCCASIONAL CELL COULD CONTINUE THROUGH MIDNIGHT.
