AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
941 PM MST SUN FEB 7 2016

.SYNOPSIS...HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER
FEATURE ACROSS THE REGION THROUGH THE UPCOMING WEEK.

&&

.DISCUSSION...AN UPPER RIDGE CONTINUES TO STRENGTHEN OVER THE WEST
COAST STATES KEEPING A DRY AND STABLE N-NW FLOW ALOFT OVER UTAH. A
NORTHERLY PRESSURE GRADIENT DRAPED ACROSS FAR SOUTHERN UTAH
CONTINUES TO BRING LOCALLY BREEZY WINDS TO THE CANYONS OF WASHINGTON
COUNTY. HOWEVER...THE GRADIENT WILL GRADUALLY RELAX OVERNIGHT AND
700MB WINDS WILL TURN MORE EASTERLY SO EXPECT THE WINDS TO DIMINISH
BY TOMORROW MORNING. OTHERWISE...VALLEY INVERSIONS CONTINUE TO TRAP
LOW-LEVEL MOISTURE WHICH MAY BE ENHANCED IN SOME AREAS BY MELTING
SNOW...SEEING AS HOW THERE WAS EXCELLENT SOLAR INSOLATION AND
SLIGHTLY WARMER TEMPERATURES TODAY. THIS WILL CONTINUE TO RESULT IN
PATCHY FOG DEVELOPMENT AGAIN TONIGHT ESPECIALLY WITH MOSTLY CLEAR
SKIES ALLOWING FOR EXCELLENT RADIATIVE COOLING. BASED ON
OBS...COVERAGE OF FOG SO FAR SEEMS A BIT LESS THAN LAST NIGHT AT
THIS TIME DUE POSSIBLY TO A BIT MORE MIXING THIS AFTERNOON.
NEVERTHELESS...FEEL THE PATCHY FOG FOR MANY VALLEY AREAS TONIGHT PER
CURRENT FORECAST IS REASONABLE.

NO UPDATES THIS EVENING.

&&

.AVIATION...AT THE SLC TERMINAL...MVFR CONDITIONS IN HAZE ARE
EXPECTED TO PREVAIL OVERNIGHT BUT MAY OCCASIONALLY DIP TO IFR FOR
PERIODS OVERNIGHT. 60 PERCENT CHANCE OF IMPROVING TO VFR FOR BRIEF
PERIODS. LIGHT NORTHWEST WINDS ARE EXPECTED TO SHIFT TO THE
SOUTHEAST BY 05-06Z.

&&

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