AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1001 AM MDT THU OCT 30 2014

.SYNOPSIS...SOUTHERLY FLOW WILL DEVELOP OVER THE AREA FRIDAY AND
CONTINUE INTO SATURDAY AS A PACIFIC STORM MOVES THROUGH THE AREA
SATURDAY AND SUNDAY.

&&

.DISCUSSION...RIDGE AXIS ALOFT JUST ALONG WESTERN EDGE OF FORECAST
AREA THIS MORNING. AS RIDGE MOVES EAST SOUTHERLY FLOW WILL
GRADUALLY INCREASE AHEAD OF PACIFIC TROUGH.

OVERNIGHT MODELS AND QUICK LOOK AT EARLY PART OF 12Z GFS ARE ALL
GENERALLY SIMILAR IN WEAKENING THE DEEP TROUGH NOW IN EAST PACIFIC
AS IT MOVES THROUGH WESTERN STATES. LOOKS LIKE ONLY A MODEST
PRECIP EVENT FOR MOST OF FORECAST AREA AT THIS TIME WITH QUITE A
BIT OF SOUTHWEST WIND AHEAD OF AND IMMEDIATELY BEHIND THE TROUGH
AS THE COLD FRONT SWINGS UP FROM THE SOUTHWEST SATURDAY. BIGGEST
IMPACT LOOKS LIKE IT WILL BE THE WIND. SNOW IN THE MOUNTAINS LOOKS
TO BE GENERALLY 6 INCHES OR LESS. STILL SOME THREAT FOR LAKE
EFFECT NEAR THE GSL...BUT NOT AN IDEAL SET UP. WILL DISCUSS THIS
STORM IN GREATER DETAIL IN AFTERNOON DISCUSSION AFTER SEEING 12Z
RUNS.

OTHERWISE ANOTHER BEAUTIFUL FALL DAY...NO CHANGES TO FORECAST AT
THIS TIME.

&&

.AVIATION...WINDS AT THE SLC TERMINAL ARE EXPECTED TO SWITCH TO THE
NORTHWEST BETWEEN 19Z AND 21Z TODAY. VFR CONDITIONS WILL PREVAIL
THROUGH THE DAY UNDER MOSTLY CLEAR SKIES.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
