AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1005 AM MDT THU AUG 9 2007

.SYNOPSIS...A DRY SOUTHWEST FLOW WILL REMAIN ACROSS THE REGION
THROUGH FRIDAY. MOISTURE WILL RETURN TO UTAH SATURDAY AND REMAIN
ACROSS THE REGION THROUGH MIDWEEK.

&&

.DISCUSSION...SUNNY SKIES ARE WIDESPREAD ACROSS THE REGION THIS
MORNING. A RELATIVELY WELL DEFINED VORT MAX IS MOVING ACROSS
NEVADA AT THIS TIME. THIS SHORTWAVE IS EXPECTED TO WEAKEN AS IT
CROSSES NEVADA LATE THIS MORNING INTO THIS AFTERNOON. THIS WAS
PICKED UP WELL BY BOTH THE 12Z NAM AND THE 12Z GFS.

WATER VAPOR IMAGERY INDICATES SOME MID-LEVEL MOISTURE REMAINS
ACROSS MAINLY THE NORTHERN HALF OF UTAH THIS MORNING. THIS
MOISTURE...IN ASSOCIATION WITH THE SHORTWAVE SHOULD BE ENOUGH TO
DEVELOP MAINLY HIGH BASED THUNDERSTORMS OVER THE HIGHER TERRAIN
THIS AFTERNOON. UPDATED TO ADD A CHANCE OF DRY THUNDERSTORMS WITH
GUSTY WINDS TO THE NORTHERN WASATCH MOUNTAINS AND TO INCREASE SKY
COVER OVER EXTREME SOUTHWESTERN WYOMING.

AS THE MEAN RIDGE MOVES WEST SATURDAY...EXPECT MID-LEVEL MOISTURE
TO INCREASE ACROSS MUCH OF THE REGION. BOTH GFS/EC INDICATE THIS
PATTERN WILL BE PERSISTENT THROUGH MID-WEEK NEXT WEEK.

&&

.AVIATION...GUSTY SOUTH WINDS ARE EXPECTED TO DEVELOP BY LATE
MORNING AT KSLC...AND CONTINUE THROUGH THE AFTERNOON. THIS SHOULD
DELAY THE WIND SHIFT TO NORTHWEST ASSOCIATED WITH THE PASSING LAKE
BREEZE UNTIL AT LEAST 22Z. THERE IS A 30 PERCENT CHANCE THIS WIND
SHIFT WILL NOT OCCUR TODAY.

&&

.FIRE WEATHER...A WEAK STORM SYSTEM MOVING THROUGH THE AREA WILL
BRING GUSTY SOUTH TO SOUTHWEST WINDS TO PORTIONS OF THE FIRE
DISTRICT TODAY. A FEW SPOTS OVER THE WESTERN VALLEYS AND SOUTHWEST
UTAH WILL SEE GUSTS GREATER THAN 30 MPH THIS AFTERNOON. HUMIDITIES
REMAIN VERY LOW ACROSS THE FIRE DISTRICT...BUT CURRENTLY FUELS DO
NOT REMAIN CRITICAL ENOUGH TO WARRANT A RED FLAG WARNING. WINDS WILL
DECREASE SLIGHTLY TOMORROW THROUGH THE WEEKEND. ISOLATED DRY
THUNDERSTORMS CAN BE EXPECTED OVER THE HIGH TERRAIN TODAY AND
TOMORROW BEFORE MOISTURE INCREASES THIS WEEKEND...WHICH COULD RESULT
IN GREATER COVERAGE OF DRY THUNDERSTORMS.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
