AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
850 PM MST TUE FEB 9 2016

.SYNOPSIS...STRONG HIGH PRESSURE ACROSS THE INTERIOR WEST WILL
REMAIN THE DOMINANT WEATHER FEATURE THROUGH THE BALANCE OF THE
WORK WEEK.

&&

.DISCUSSION...THE AXIS OF THE STRONG RIDGE REMAINS ALONG THE
UT/NV BORDER THIS EVE WITH A SOLID INVERSION IN PLACE IN MOST
VALLEYS. FOG AND STRATUS THAT FORMED OVER THE WEST DESERTS LAST
NIGHT FAILED TO DISSIPATE THIS AFTN AND IS BEGINNING TO EXPAND
AGAIN AT THIS TIME. THE FOG THAT FORMED IN THE CACHE AND BEAR
RIVER VALLEYS DID BURN OFF BUT IS CURRENTLY REDEVELOPING IN THE
CACHE VALLEY AND SHOULD DO THE SAME IN THE BEAR RIVER VALLEY AS
WELL AS LOCALLY ACROSS THE VALLEY BOTTOMS ALONG THE WASATCH FRONT
AND BACK INCLUDING ALONG THE SHORES OF THE GREAT SALT LAKE.

FOG DID REACH THE NORTH END OF THE RUNWAY COMPLEX AT THE SLC
AIRPORT AROUND SUNRISE THIS MORNING AND IT IS LIKELY THIS WILL
HAPPEN AGAIN TONIGHT. IT IS POSSIBLE IT COULD SPREAD ACROSS THE
ENTIRE AIRPORT LATE TONIGHT AND WORK ITS WAY FARTHER SOUTH INTO
THE SALT LAKE VALLEY.

THE RIDGE REMAINS PRETTY MUCH IN PLACE THRU FRI WITH MANY OF THE
FORECAST ELEMENTS REMAINING THE SAME OR SIMILAR THROUGH THAT TIME.
THE DIFFICULT PART OF THE FORECAST IS DETERMINING JUST HOW
PERSISTENT THE FOG/STRATUS WILL BE EACH DAY AND WHETHER OR NOT IT
BURNS OFF IN THE AFTERNOONS. AS OF NOW WE HAVE IT BURNING OFF
TOMORROW AFTERNOON PRETTY MUCH ALL AREAS BUT CONFIDENCE IN THAT
OCCURRING IS NOT HIGH ESPECIALLY ACROSS THE WEST DESERT.

NO UPDATES PLANNED AT THIS TIME.

&&

.AVIATION...DENSE FOG WILL LIKELY FORM ALONG THE NORTH END OF THE
SLC TERMINAL RUNWAY COMPLEX AGAIN TONIGHT...WITH A 40 PERCENT
CHANCE THAT THIS FOG SPREADS ACROSS THE ENTIRE TERMINAL AT SOME
POINT. THE MOST LIKELY TIME FOR THIS FOG TO DEVELOP IS BETWEEN 08Z
AND 14Z...WITH ANY IMPACTS POTENTIALLY LINGERING THROUGH 18Z.
WINDS WILL BE VERY LIGHT AND OCCASIONALLY VARIABLE IN DIRECTION.

&&

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