.DISCUSSION...PACIFIC TROUGH JUST NOW ENTERING WESTERN UTAH WITH
ASSOCIATED COLD FRONT DRAPED ON A LINE FROM DELTA TO PRICE.

DAYLIGHT HOURS. THE AREA WILL REMAIN CLEAR AND DRY FOR THE NEXT
SEVERAL HOURS...BUT PRECIPITATION POTENTIAL WILL INCREASE RAPIDLY
WITH FRONTAL PASSAGE. NUMEROUS SHOWERS AND THE POTENTIAL FOR A
ROGUE THUNDERSTORM ARE EXPECTED FOR THE AFTERNOON HOURS WITH
WETTING RAIN POTENTIAL POSSIBLE DURING THAT TIME. TEMPS TO
COOL AND RH TO CLIMB TODAY.

DRY CONDITIONS WILL RETURN TO THE BURN SITE TONIGHT...WITH TEMPS
REBOUNDING FOR SATURDAY. HIGH PRESSURE WILL DOMINATE LOCAL
WEATHER THEREAFTER THROUGH EARLY NEXT WEEK WITH A WARMING/DRYING
TREND.
