AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1029 AM MST FRI FEB 12 2016

.SYNOPSIS...HIGH PRESSURE OVER UTAH TODAY WILL WEAKEN AS A COUPLE
OF WEAK WEATHER DISTURBANCES CROSS NORTHERN UTAH THIS WEEKEND.
HIGH PRESSURE ALOFT WILL REBOUND ACROSS THEN REGION EARLY NEXT
WEEK.

&&

.DISCUSSION...A STRONG RIDGE REMAINS IN PLACE ACROSS THE FORECAST
TODAY. THIS IS KEEPING A STABLE AIRMASS IN PLACE...WITH WARM AND DRY
CONDITIONS ALOFT WHILE VALLEY INVERSIONS ARE KEEPING FOG AND STRATUS
MIRED IN MANY OF THE VALLEYS OF NORTHERN AND CENTRAL UTAH. STRATUS
AND DENSE FOG ARE LOCATED IN SIMILAR AREAS AS YESTERDAY...WITH THE
WORST OF IT IN THE UTAH COUNTY AREA. BECAUSE COVERAGE OF DENSE FOG
HAS DECREASED OVER THE LAST COUPLE OF HOURS...HAVE ALLOWED THE DENSE
FOG ADVISORY TO EXPIRE. ALTHOUGH STRATUS MAY ERODE SOMEWHAT ALONG
THE EDGES AGAIN TODAY...IT IS UNLIKELY TO COMPLETELY BURN OFF AND
VALLEYS UNDERNEATH IT WILL REMAIN ON THE COOLER SIDE. AS A
RESULT...A GOOD FORECAST FOR TODAY WOULD BE SOMETHING CLOSE TO
PERSISTENCE.

A COUPLE OF WEAK STORM SYSTEMS ARE STILL EXPECTED TO GRAZE NORTHERN
UTAH OVER THE WEEKEND. THESE WILL BRING PROGRESSIVELY COOLER AIR
ALOFT AND SHOULD WEAKEN THE LID ON THE INVERSIONS. HOWEVER...THEY
STILL DO NOT APPEAR TO BE STRONG ENOUGH TO COMPLETELY SWEEP THE
INVERSIONS AWAY.

ONLY MADE MINOR UPDATES TO LOWER SOME VALLEY TEMPERATURES TODAY AND
AND DECREASED DENSE FOG COVERAGE FOR THE REST OF THE MORNING.

&&

.AVIATION...PREVAILING IFR CONDITIONS IN HAZE/FOG AND LOW STRATUS
ARE EXPECTED TO REMAIN IN PLACE AT THE KSLC TERMINAL THROUGH THE
VALID TAF PERIOD. LIFR IN DENSE FOG AND/OR CIGS NEAR 200 FEET ARE
ONCE AGAIN EXPECTED TO DEVELOP THIS EVENING AND PERSIST THROUGH THE
OVERNIGHT HOURS...WITH A 30 PERCENT CHANCE OVERNIGHT CONDITIONS
REMAIN IN THE IFR CATEGORY.

&&

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