AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
926 PM MST MON FEB 8 2016

.SYNOPSIS...STRONG HIGH PRESSURE ALOFT WILL REMAIN THE DOMINANT
WEATHER FEATURE ACROSS THE INTERIOR WEST THROUGHOUT THE WEEK.

&&

.DISCUSSION...A STRONG UPPER RIDGE EXTENDS OVER THE WEST COAST
STATES FROM NRN WASHINGTON TO SRN CA. A STABLE AIRMASS IS OVER OUR
CWA WITH A STRONG SURFACE HIGH CENTERED OVER SERN ID. INVERSIONS
REMAIN WELL DEVELOPED IN MOST VALLEYS BUT THERE HAS BEEN SOME
GRADUAL WARMING OF THE TRAPPED AIR WITH MILFORD REACHING ABOVE
FREEZING...DELTA THE UPPER 20S...ROOSEVELT 30...AND HANKSVILLE
INTO THE 40S.

AS A RESULT EXPECT ANY FOG OR STRATUS TO BE PRETTY LIMITED TO THE
COLDEST VALLEY BOTTOMS ACROSS THE WEST WITH NONE IN THE EAST. THE
EXCEPTION HAS BEEN ALONG THE WASATCH FRONT WHERE DEWPOINTS HAVE
BEEN COMING UP SLOWLY AT SLC AND THE CACHE VALLEY WHERE THEY HAVE
FOGGED IN ALREADY. THERE IS A POSSIBILITY THAT FOG COULD FORM
AROUND THE GREAT SALT LAKE AND CROSS THE SLC AIRFIELD LATER
TONIGHT.

THE NORTHERLY SURFACE GRADIENT HAS SLACKED OFF SOMEWHAT BUT LOCAL
GUSTY WINDS ARE STILL NOTED IN PARTS OF UTAHS DIXIE. EXPECT THESE
TO NOT GET ANY STRONGER TONIGHT HOWEVER.

LITTLE CHANGE IN THE OVERALL PATTERN IS EXPECTED THROUGH MID WEEK.

UPDATED FORECASTS EARLIER TO REMOVE SOME OF THE FOG MENTION FROM
AREAS WHERE IT IS NOT EXPECTED TONIGHT AND REDUCE SKY COVER. WILL
UPDATE AGAIN TO EXPAND THE FOG MENTION AROUND THE GREAT SALT LAKE
AND HAVE IT MENTIONED SOONER IN THE CACHE VALLEY. NO OTHER CHANGES
PLANNED.

&&

.AVIATION...AT THE SLC TERMINAL...LIGHT SOUTHERLY WINDS WILL
PREVAIL AFTER ABOUT 05Z BUT COULD BECOME LIGHT AND VARIABLE AT
TIMES. MVFR CONDITIONS IN HAZE WILL PREVAIL MOST OF THE NIGHT.
OCCASIONAL IFR VSBY IN HZ/BR IS POSSIBLE BETWEEN ABOUT 09-16Z WITH
A 20 PERCENT CHANCE OF LIFR IN FOG.

&&

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

PUBLIC...WILENSKY
AVIATION...DEWEY
