AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1029 AM MDT THU SEP 3 2015

.SYNOPSIS...AN UPPER LEVEL TROUGH WILL MOVE THROUGH THE PACIFIC
NORTHWEST TODAY AND FRIDAY...THEN PUSH A FALL COLD FRONT THROUGH
THE INTERMOUNTAIN WEST ON SATURDAY.


&&

.DISCUSSION...A DEEP TROUGH CONTINUES TO DIG INTO THE PACIFIC
NORTHWEST TODAY...WITH A WARM SOUTHWESTERLY FLOW PERSISTING OVER
UTAH AND SOUTHWEST WYOMING. SOME ADDITIONAL MOISTURE HAS MOVED
INTO THE AREA OVERNIGHT...AS EVIDENCED BY INCREASED CLOUD COVER.
THIS MOISTURE MAY ALLOW FOR SOME ISOLATED SHOWERS AND
THUNDERSTORMS THIS AFTERNOON...PARTICULARLY IN THE EASTERN PART OF
THE CWA AND UTAHS FAR NORTHWEST CORNER...BUT IN GENERAL
INSTABILITY SHOULD STILL REMAIN FAIRLY LIMITED TODAY.

AS THE TROUGH CONTINUES TO ENCROACH ON THE REGION...WINDS WILL
RAMP UP CONSIDERABLY...PARTICULARLY IN WESTERN UTAH. MAIN FORECAST
PROBLEM TODAY WILL BE DETERMINING THE STRENGTH OF THOSE
WINDS...AND WHETHER ANY HEADLINES WILL BE ISSUED TODAY.

UPDATED THE FORECAST THIS MORNING TO INCREASE CLOUD COVER ACROSS
MUCH OF THE AREA THIS MORNING...AS WELL AS TWEAK THE AFTERNOON
POPS TO ADD AN ISOLATED MENTION TO THE UINTA BASIN AND A COUPLE
OTHER LOCATIONS.

&&

.AVIATION...GUSTY SOUTH WINDS WILL CONTINUE AT THE SLC TERMINAL
THROUGH THE DAY.

&&

.FIRE WEATHER...A STRONG UPPER LEVEL TROUGH ALONG THE WEST COAST
WILL CONTINUE TO INCREASE WINDS ACROSS THE DISTRICT THROUGH
SATURDAY. HUMIDITIES ARE EXPECTED TO FALL BELOW CRITICAL THRESHOLDS
MOST AFTERNOONS ACROSS THE WESTERN HALF OF THE DISTRICT...WITH POOR
OVERNIGHT RECOVERIES. GIVEN THE ONLY ZONE WITH CRITICAL FUELS IN
UTAH CONTINUES TO BE FAR SOUTHWEST UTAH...NO HEADLINES HAVE BEEN
ISSUED...ALTHOUGH WINDS MAY BE HIGH ENOUGH TO WARRANT A FIRE WEATHER
WATCH FOR THIS ZONE FRIDAY AND SATURDAY.

A MUCH COOLER AIRMASS WILL BUILD INTO THE DISTRICT SUNDAY.

&&

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