AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
936 AM MST SAT FEB 13 2016

.SYNOPSIS...A COUPLE OF WEAK WEATHER DISTURBANCES WILL CROSS
NORTHERN UTAH THIS WEEKEND. HIGH PRESSURE ALOFT WILL REBOUND
ACROSS THE REGION EARLY NEXT WEEK.


&&

.DISCUSSION...A WEAK SHORTWAVE TROUGH HAS BEGUN BRUSHING BY UTAH
AND SOUTHWEST WYOMING THIS MORNING...WITH MID AND HIGH LEVEL
CLOUDS MOVING OVER THE NORTHERN HALF OF THE FORECAST AREA. THESE
CLOUDS ARE LARGELY OBSCURING THE SATELLITE VIEW OF THE FOG AND
STRATUS THAT HAS BECOME ENTRENCHED OVER MUCH OF WESTERN UTAH THE
PAST FEW DAYS...BUT SURFACE OBSERVATIONS INDICATE THAT MANY
LOCATIONS CONTINUE TO HAVE LOW VISIBILITIES AND/OR LOW CEILINGS.

THIS WAVE IS NOT EXPECTED TO BE STRONG ENOUGH TO SCOOP OUT THE
VALLEYS...SO IT WILL BE INTERESTING TO SEE WHETHER IT WILL BE
CAPABLE OF HELPING TO ERODE THE INVERSION IMPACTS AT ALL.
FOLLOWING THE EXIT OF THIS INITIAL TROUGH...THE PRIMARY FORECAST
CHALLENGE FOR THE DAY WILL BE DETERMINING WHAT EFFECTS THE
SUNDAY/MONDAY WAVES WILL HAVE IN TERMS OF PRECIPITATION AND
MIXING.

THE DENSE FOG ADVISORY WAS ALLOWED TO EXPIRE AS SCHEDULED...AS FOG
ACROSS UTAH COUNTY HAS STARTED TO BECOME MORE PATCHY. THAT
SAID...THE FORECAST WAS UPDATED TO INCLUDE PATCHY FOG ACROSS
WESTERN UTAH INTO THE AFTERNOON HOURS...AS EARLY INDICATIONS ARE
THAT THIS WAVE WILL HAVE LITTLE IMPACT ON THE FOG. WILL ALSO HAVE
TO LOOK CLOSER AT ADDING FOG BACK INTO THE FORECAST FOR TONIGHT.



&&

.AVIATION...IFR/LIFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE
MORNING AT THE SLC TERMINAL. CONDITIONS SHOULD IMPROVE TO MVFR
BETWEEN 20Z AND 22Z...BUT THERE IS A 30 PERCENT CHANCE OF IFR
CONDITIONS PREVAILING THROUGHOUT THE DAY. LIGHT WINDS ARE EXPECTED
TO BECOME PREVAILING NORTHWESTERLY BY 20Z.

&&

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