AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
959 PM MDT SUN AUG 30 2015

.SYNOPSIS...A COLD FRONT DRAPED ACROSS CENTRAL UTAH THIS EVENING
WILL WEAKEN OVERNIGHT. WEAK HIGH PRESSURE BEGINS TO BUILD BACK
INTO THE AREA ON MONDAY AHEAD OF ANOTHER STORM SYSTEM APPROACHING
THE PACIFIC NORTHWEST. THIS WILL PLACE UTAH AND SOUTHWEST WYOMING
UNDER A DRIER SOUTHWEST FLOW ALOFT RESULTING IN A SLOW WARMING AND
DRYING TREND.

&&

.DISCUSSION...UPPER LEVEL TROUGH MOVING THROUGH THE NORTHERN
INTERMOUNTAIN REGION THIS EVENING. SHOWERS AND ISOLATED
THUNDERSTORMS CONTINUE TO DEVELOP THIS EVENING ALONG A STALLED
MID LEVEL BAROCLINIC BOUNDARY STRETCHING FROM WEST CENTRAL UTAH
INTO SOUTHWEST WYOMING. BELIEVE THAT THIS TREND WILL CONTINUE INTO
THE OVERNIGHT HOURS BEFORE DIMINISHING. MEANWHILE...COVERAGE OF
SHOWERS AND THUNDERSTORMS IS DECREASING ACROSS SRN AND ERN UTAH AS
STORMS SLIDE TO THE EAST WITH DEPARTING WEAK MID LEVEL SHORTWAVE.
ANTICIPATE THAT SHOWERS AND STORMS WILL CEASE AS THE BACK END OF
CURRENT AREA OF PRECIP SHIFTS TO THE. OTHERWISE...EXPECT
DECREASING CLOUD COVER ACROSS MOST OF THE STATE AFTER MIDNIGHT
ALTHOUGH A BIT MORE CLOUD COVER IS LIKELY TO LINGER FROM WEST
CENTRAL UTAH THROUGH SW WY ALONG MID LEVEL BAROCLINIC ZONE. LOW
TEMPERATURES WILL BE ABOUT 10 DEGREES F COOLER THAN LAST
NIGHT...GENERALLY AROUND 60 DEGREES F ALONG THE WASATCH FRONT.

UPPER LEVEL TROUGH OVER THE NORTHERN INTERMOUNTAIN REGION TONIGHT
WILL QUICKLY LIFT INTO THE NRN PLAINS ON MONDAY AS WEAK RIDGING
BEGINS TO BUILD BACK INTO THE GREAT BASIN AHEAD ANOTHER TROUGH
THAT IS APPROACHING THE PACIFIC NW. THIS ALLOWS SOUTHWEST FLOW
ALOFT TO DEVELOP AND TEMPERATURES TO BEGIN A MODEST REBOUND.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED AT THE KSLC TERMINAL
THROUGH THE TAF PERIOD. LIGHT SOUTHEAST WINDS ARE EXPECTED TO
CONTINUE THROUGH THE MORNING PUSH. HOWEVER...LIGHT SHOWERS IN THE
AREA WILL BRING A 10 PERCENT CHANCE OF ERRATIC WINDS THOUGH 0900
UTC.

&&

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