NATIONAL WEATHER SERVICE SALT LAKE CITY UT
429 PM MDT WED SEP 28 2011

.DISCUSSION...HIGH PRESSURE WILL DOMINATE THE WEATHER FOR THE NEXT
COUPLE DAYS...LEADING TO DRY AND WARM CONDITIONS. NEXT TO ZERO
TRANSPORT WINDS ON THURSDAY WILL GIVE WAY TO SLIGHTLY INCREASED
TRANSPORT WINDS ON FRIDAY. AT THE MOMENT IT LOOKS LIKE THESE
WINDS WILL BE JUST ENOUGH TO GET CLEARING INDICES ABOVE 500 ON
FRIDAY. THERE IS A CHANCE THAT SURFACE WINDS AT THE BURN SITE ON
FRIDAY WILL BECOME LIGHT UPSLOPE/UPVALLEY IN THE LATE MORNING AND
EARLY AFTERNOON...PARTICULARLY IN THE AREAS FURTHER AWAY FROM THE
RIDGELINE.

CLEARING INDICES WILL DEFINITELY BE ABOVE 500 FOR SATURDAY...AS
TRANSPORT WINDS INCREASE EVEN MORE. THIS WILL LIKELY LEAD TO
SOMEWHAT GUSTY SOUTHWEST WINDS AT THE BURN SITE ON SATURDAY
AFTERNOON. INCREASED MOISTURE WILL ALSO MOVE INTO NORTHERN UTAH
ON SATURDAY...LEADING TO HIGHER RH VALUES ON SATURDAY AND
SATURDAY NIGHT...AS WELL AS A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS. ALSO EXPECT SOMEWHAT COOLER TEMPERATURES AND
INCREASED CLOUD COVER WHEN COMPARED TO FRIDAY. THIS INCREASED
MOISTURE WILL REMAIN IN PLACE INTO THE BEGINNING OF NEXT WEEK.
