AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
949 AM MST WED NOV 20 2013

.SYNOPSIS...ANOTHER WEAK BUT MOIST SYSTEM WILL CROSS THE AREA
TODAY. A COLD FRONT WILL MOVE SOUTH THROUGH THE EASTERN GREAT
BASIN TONIGHT AND TOMORROW. A CALIFORNIA LOW WILL KEEP MOISTURE OVER
CENTRAL AND SOUTHERN UTAH FRIDAY THROUGH THE WEEKEND.

&&

.DISCUSSION...MOIST WESTERLY FLOW REMAINS OVER THE FORECAST AREA
THIS MORNING...RESULTING IN WIDESPREAD CLOUDS. NEXT IN A SERIES OF
WEAK SHORTWAVES TO IMPACT THE AREA IS MAKING ITS WAY OVER SOUTHERN
UTAH...AND PRECIP COVERAGE IS INCREASING THERE. COVERAGE WILL
CONTINUE TO INCREASE AND SPREAD NORTHWARD THIS AFTERNOON WITH THE
ADDITION OF SHORTWAVE ENERGY. CLOUDS WILL LIMIT WARMING BUT THE
AIRMASS IS STILL MILD OVER THE REGION...SO MAXES SHOULD STILL RUN
A FEW DEGREES ABOVE SEASONAL NORMALS.

A PACIFIC NORTHWEST TROUGH WILL DROP DOWN TO THE SOUTHERN
CALIFORNIA COAST BY TOMORROW AFTERNOON AS A SECOND COLD TROUGH
MOVES INTO THE NORTH CENTRAL UNITED STATES. THE FORECAST AREA WILL
BE PUT IN A DEFORMATION ZONE IN BETWEEN THESE FEATURES...AND A
FAIRLY WELL DEFINED COLD FRONT WILL PROVIDE ADDITIONAL
INSTABILITY. THIS FRONT IS PROGGED TO MOVE INTO NORTHERN UTAH
TOMORROW MORNING AND THROUGH SOUTHERN UTAH BY EARLY TOMORROW
EVENING. SNOW LEVELS SHOULD REMAIN ABOVE THE VALLEYS...BUT SNOW
COULD BE SIGNIFICANT OVER THE MOUNTAINS...PARTICULARLY OVER
CENTRAL AND SOUTHERN UTAH AS PRECIPITATION ALONG THE FRONT LOOKS
TO BECOME MORE ORGANIZED DURING THAT TIME. WILL NEED TO CONSIDER
HEADLINES WITH THE AFTERNOON FORECAST PACKAGE.

BEHIND THE FRONT...MODELS CONTINUE TO INDICATE A FAIRLY STRONG
E/NE FLOW DEVELOPING UNDER THE INFLUENCE OF THE CALIFORNIA TROUGH.
GOOD PRESSURE GRADIENT SUPPORTS A FAIRLY STRONG DOWNSLOPE/CANYON
WIND EVENT FOR THE WASATCH FRONT. BEST WINDOW FOR STRONGER WINDS
OCCURS THURSDAY NIGHT INTO EARLY FRIDAY...BUT AT LEAST SOME
EASTERLY FLOW PERSISTS INTO SATURDAY. PRESSURE GRADIENT ALSO
SUPPORTS SOME GAP WINDS IN SOUTHWEST UTAH...THOUGH DIRECTION OF
THE FLOW (MORE EAST THAN NORTHEAST) IS NOT PARTICULARLY FAVORABLE.

THE AIRMASS OVER NORTHERN UTAH DRIES QUICKLY BEHIND THE
FRONT...BUT MOISTURE LOOKS TO LINGER OVER CENTRAL AND SOUTHERN
UTAH INTO THE WEEKEND AS THE CALIFORNIA TROUGH SLOWLY MEANDERS
ACROSS ARIZONA.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...CEILINGS AT THE SLC TERMINAL WILL LOWER THROUGH TODAY AS
SHOWERS MOVE IN TO THE AREA. CEILINGS WILL LIKELY DROP BELOW 7000FT
BETWEEN 19Z AND 22Z...WITH ONLY A SLIGHT CHANCE THAT THEY REMAIN
ABOVE THAT LEVEL THROUGH 00Z. OTHER POTENTIAL IMPACTS FROM SHOWERS
INCLUDE BRIEF ERRATIC WINDS AND MVFR CONDITIONS FROM THE HEAVIER
RAIN BANDS.

&&

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

PUBLIC...TRAPHAGAN
AVIATION...SCHOENING
