AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
914 AM MST FRI NOV 27 2015

.SYNOPSIS...A COLD UPPER LEVEL LOW PRESSURE SYSTEM WILL REMAIN
OVER THE GREAT BASIN THROUGH THE REMAINDER OF THE THANKSGIVING
HOLIDAY WEEKEND. HIGH PRESSURE ALOFT WILL SETTLE INTO THE REGION
EARLY NEXT WEEK.

&&

.DISCUSSION...LIGHT SNOW HAS BECOME MORE WIDESPREAD THIS MORNING
ACROSS SOUTHWEST AND CENTRAL UTAH AS A JET STREAK ROUNDS THE BASE
OF THE LOW OVER NEVADA AND CREATES DIFFLUENCE ALOFT IN COMBO WITH
WEAK 700MB WARM ADVECTION THROUGHOUT THIS AREA. ALTHOUGH THE JET
SUPPORT MOVES INTO NORTHEAST UTAH BY AFTERNOON THE SOUTHEAST FLOW
OF WARM ADVECTION WILL CONTINUE INTO THE AFTERNOON. THEREFORE HAVE
INCREASED POPS OVER A LARGE AREA FROM SOUTHWEST UTAH ACROSS WEST
CENTRAL AND CENTRAL THROUGH THE DAY. QPF AMOUNTS ARE NOT EXPECTED
TO EXCEED 0.10 OR SO OF AN INCH BUT WITH COLD TEMPERATURES SOME
LIGHT ACCUMULATING SNOW IS EXPECTED. UDOT ROAD CAMERAS SHOWING
MANY ROADS ACROSS THIS AREA HAVING A LIGHT DUSTING AT SUNRISE.
TRAVEL SHOULD BE MINIMALLY IMPACTED BY LATE MORNING AS INSOLATION
FROM THE SUN THROUGH THE CLOUDS AND ROADS BEING TREATED WILL KEEP
ROADS FROM BECOMING SNOW PACKED DESPITE TEMPERATURES REMAINING
BELOW FREEZING. HAVE LOWER TEMPERATURES BY A FEW DEGREES UNDER
THIS AREA OF SNOW FOR TODAY.

ACROSS THE NORTHERN WASATCH FRONT WILL KEEP THE HIGH WIND WARNING
IN AFFECT THROUGH MIDDAY AS THE WINDS ARE STILL GUSTING TO NEAR 50
MPH WELL WITHIN WIND ADVISORY CRITERIA. HOWEVER...WILL DROP THE
WIND ADVISORY FOR THE CACHE VALLEY AS WINDS HAVE FALLEN BELOW
ADVISORY LEVELS THERE. THE LATEST NAM BUFFER SOUNDING SHOWS THAT
THERE IS POTENTIAL FOR THE EASTERLY DOWNSLOPE WINDS ALONG THE
NORTHERN WASATCH TO PEAK INTO ADVISORY LEVELS THIS EVENING. WILL
TAKE A CLOSER LOOK AS OTHER MODEL COME IN AND SEE IF ANOTHER WIND
ADVISORY IS WARRANTED FOR TONIGHT.

&&

.AVIATION...THE PRIMARY OPERATIONAL WEATHER CONCERN FOR THE KSLC
TERMINAL CONTINUES TO FOCUS ON PREVAILING WIND DIRECTION ACROSS THE
AIRFIELD. CANYON WINDS ACROSS THE EAST BENCHES HAVE CREATED A
SURFACE EDDY LOCALLY...DRIVING PERIODIC WEST TO WEST NORTHWEST WINDS
TO OCCUR ALTHOUGH THE PREVAILING DIRECTION REMAINS BETWEEN THE EAST-
SOUTHEAST AND SOUTHWEST. BETWEEN 18-20Z THE PREVAILING DIRECTIONS
ARE EXPECTED TO PHASE MORE TO A WEST-NORTHWEST FOR THE REMAINDER OF
THE AFTERNOON. A 20 PERCENT CHANCE EXISTS THAT ROGUE EASTERLY GUSTS
TO 20 KNOTS WILL OCCUR THROUGH 18Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...HIGH WIND WARNING UNTIL NOON MST TODAY FOR UTZ002.

WY...NONE.
