SPOT FORECAST FOR ROUNDABOUT
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
417 PM MDT WED OCT 3 2012

.DISCUSSION...A COLD FRONT LIES JUST NORTH OF THE ROUNDABOUT FIRE
AS OF 1600. WESTERLY WINDS ARE EXPECTED TO CONTINUE TO INCREASE
OVER THE NEXT FEW HOURS AS THE FRONT EVER SO SLOWLY APPROACHES.
HUMIDITY VALUES HAVE LIKELY BOTTOMED OUT AT THE SITE AND WILL
ONLY GRADUALLY INCREASE THROUGH FRONTAL PASSAGE AROUND 2000. THE
FRONT IS LOSING STRENGTH BUT WILL HOLD TOGETHER ENOUGH TO BRING A
SHIFT TO NORTHERLY WINDS AT THAT TIME THEN HOLD MOST NIGHT.
COOLER AIR WILL MOVE IN TO AID DECOUPLING OF WINDS LATE NIGHT
ALLOWING FOR LIGHTER SLOPE FLOWS BY DAWN. THURSDAY WILL BRING
ANOTHER DAY OF VERY DRY CONDITIONS BUT WINDS WILL BE QUITE A BIT
LIGHTER VERSUS TODAYS. SMOKE DISPERSAL WILL BE LESS HOWEVER WITH
CLEARING INDICES FALLING DRAMATICALLY.
