SOUTH TO SOUTHWEST WINDS HAVE FLUSHED OUT SOME LOW LEVEL MOISTURE
WEST OF THE RANGES...BUT DEW POINTS IN THE 50S HAVE BEEN LINGERING
EAST OF THE MOUNTAINS.  A FEW THUNDERSTORMS MOVING NORTH OUT OF
COLORADO LATE THIS AFTERNOON SHOULD BE ABLE TO MAKE IT INTO THE
SOUTHERN PART OF THE FORECAST AREA BEFORE SUNSET.  OTHER SHOWERS AND
THUNDERSTORMS POSSIBLE IN THE NORTHERN PART OF THE AREA AS SOUTHEAST
WINDS INTERACT WITH A WARM FRONT.  MOST OF THE OVERNIGHT HOURS
SHOULD REMAIN DRY...WITH A FEW MORE LATE DAY SHOWERS AND
THUNDERSTORMS ON SATURDAY.  TEMPS ARE THE MAIN CONCERN TOMORROW...
WITH 700 MB TEMPS SUPPORTING ANOTHER DAY OF 80S AND 90S. A WEAK COLD
FRONT COMES THROUGH EARLY SUNDAY...WHICH SHOULD HOLD TEMPS DOWN SOME.
HOWEVER...THE RESPITE FROM HIGH TEMPS AND LOW RH LOOKS TO BE SHORT-
LIVED.

.EXTENDED...
THE TREND IS STILL TOWARD HOT AND CONTINUED DRY FOR THE EXTENDED
PERIOD. A PERSISTENT UPPER LEVEL RIDGE IS EXPECTED TO INTENSIFY OVER
THE INTER-MOUNTAIN REGION WITH A STRONG NEGATIVE HEIGHT ANOMALY OVER
ALASKA. THIS HAS BEEN WELL ADVERTISED AND IS IN ALL LONG RANGE
MODELS. ASIDE FROM SOME PM THUNDERSTORMS IN EXTREME SOUTHEAST
WYOMING IN THE EARLY PART OF NEXT WEEK...HOT AND DRY SHOULD BE THE
