AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
953 AM MST SUN FEB 7 2016

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

&&

.DISCUSSION...A STRONG UPPER RIDGE REMAINS CENTERED OVER THE WEST
COAST THIS MORNING WITH A NORTHWESTERLY FLOW ALOFT OVER THE CWA.
SURFACE HIGH PRESSURE REMAINS CENTERED OVER THE NRN GREAT BASIN
WITH WELL DEVELOPED VALLEY INVERSIONS IN PLACE IN MOST OF OUR
VALLEYS. THE STRONG NWLY FLOW ALOFT IS TOUCHING THE HIGHEST PEAKS
ACROSS THE NRN MTNS WITH GUSTS OVER 60 MPH NOTED. DO NOT EXPECT
THESE WINDS TO DESCEND MUCH AND THEY SHOULD GRADUALLY ABATE
THROUGH THE DAY.

STRATUS AND FOG IS NOT QUITE AS EXTENSIVE THIS MORNING ACROSS THE
CWA POSSIBLY DUE TO THE STRONGER FLOW ALOFT ACROSS THE NORTH BUT
IT IS ALSO POSSIBLE THAT THERE WAS JUST ENOUGH WEAK STIRRING OF
THE AIRMASS IN THE INVERSIONS YESTERDAY TO MIX IN A LITTLE DRIER
AIR. ALSO WE ARE GETTING CLOSE TO THE END OF FOG SEASON WITH THE
DAYS GETTING LONGER AND THE SUN ANGLE INCREASING. THERE IS HOWEVER
MORE HAZE IN THE BOTTOM OF THE SALT LAKE VALLEY THIS MORNING.

EXPECT A STRONG RADIATIVE NIGHT TONIGHT UNDER CLEAR SKIES WITH
THE RIDGE SHIFTING SLOWLY INLAND AND THE FLOW ALOFT DIMINISHING.
SO WOULD EXPECT THE FOG AND STRATUS TO BECOME A LITTLE MORE
WIDESPREAD AGAIN. VERY MINIMAL MIXING MONDAY SHOULD PREVENT MUCH
STIRRING OF THE VALLEYS AND EXPECT SOME AREAS OF STRATUS TO LINGER
THRU THE DAY WITH A REPEAT OF FOG AND STRATUS DEVELOPMENT MON
NIGHT. EXPECT HAZE TO CONTINUE TO INCREASE IN THE SALT LAKE VALLEY
AND ALONG THE WASATCH FRONT IN GENERAL BUT STILL AM NOT EXPECTING
FOG AT SLC.

FOR NOW HAVE REDUCED SKY COVER TODAY AND EXTENT OF FOG IN THE
GRIDS FOR THIS MORNING. ALSO BUMPED WINDS UP A BIT ACROSS WY. NO
OTHER CHANGES PLANNED.

&&

.AVIATION...AT THE SLC TERMINAL...MVFR VISIBILITIES IN HAZE ARE
EXPECTED TO IMPROVE TO VFR BETWEEN 18Z AND 20Z...BUT THERE IS A 30
PERCENT CHANCE REDUCED VISIBILITIES WILL HANG ON LONGER THAN
EXPECTED. SOUTHEAST WINDS ARE EXPECTED TO SHIFT TO THE NORTHWEST
BETWEEN 18Z AND 20Z.

&&

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