NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1129 AM MDT TUE SEP 6 2011

.DISCUSSION...THE WEATHER DISTURBANCE THAT BROUGHT RAIN TO THE FIRE
SITE THIS MORNING WILL BE WELL EAST OF THE AREA BY TONIGHT. A
STABLE AIR MASS TRAILING THIS FEATURE WILL END THE THREAT OF
PRECIP...BUT WILL LEAD TO RATHER POOR SMOKE DISPERSAL FOR AT LEAST
THE NEXT COUPLE OF DAYS. MODERATE EASTERLY CANYON WINDS ALONG THE
NORTHERN WASATCH FRONT MAY BE STRONG ENOUGH TO REACH THE FIRE SITE
LATE TONIGHT/WEDNESDAY MORNING...BUT TRANSPORT WINDS WILL WEAKEN
SUBSTANTIALLY AT 2 TO 3 THOUSAND FEET ABOVE GROUND LEVEL. CLEARING
INDICES COULD INCREASE A BIT THURSDAY AS THE SIMILAR CANYON WINDS
WILL DEVELOP WITH SLIGHTLY STRONGER AND DEEPER EASTERLY FLOW ALOFT
THROUGH THURSDAY MORNING. WORTH NOTING IS THAT BOTH WEDNESDAY AND
THURSDAY AFTERNOONS THE CLEARING INDICES COULD POTENTIALLY LOWER DUE
TO THE LIGHT WINDS NEAR THE GREAT SALT LAKE.
