AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1059 AM MDT FRI OCT 20 2006

.SYNOPSIS...A PACIFIC STORM SYSTEM WILL PUSH A COLD FRONT THROUGH
UTAH TODAY. HIGH PRESSURE WILL BUILD ACROSS THE REGION LATE IN THE
WEEKEND THROUGH EARLY NEXT WEEK.

&&

.DISCUSSION...JET STREAK ASSOCIATED WITH THE APPROACHING PACIFIC
STORM SYSTEM HAS BEGUN TO NOSE INTO NORTHERN UTAH THIS MORNING.
ISOLATED SHOWERS CONTINUE OVER NORTHEASTERN UTAH BUT MORE
WIDESPREAD PRECIPITATION IS OCCURRING IN SOUTHEASTERN IDAHO NEAR
THE CYCLONIC SIDE OF THE JET AND ALONG THE UPPER TROUGH INTO
WYOMING. PRECIPITATION COVERAGE WILL SHIFT SOUTH THIS AFTERNOON AS
THE STORM SYSTEM CONTINUES TO TRACK SOUTH INTO NORTHERN
UTAH...WITH WIDESPREAD PRECIPITATION EXPECTED TO DEVELOP OVER THE
NORTHERN WASATCH MOUNTAINS...THE UINTA MOUNTAINS...AND
SOUTHWESTERN WYOMING. THE NORTHERN WASATCH SHOULD SEE LOW END
ADVISORY AMOUNTS TODAY INTO THIS EVENING...AND A SNOW ADVISORY
REMAINS IN EFFECT UNTIL 8 PM. HOWEVER...PRECIPITATION CHANCES DROP
OFF SIGNIFICANTLY TO THE WEST OF THIS AREA ON THE ANTICYCLONIC
SIDE OF THE JET. SCATTERED SHOWERS ARE EXPECTED TODAY ALONG THE
WASATCH FRONT...BUT LITTLE IN THE WAY OF PRECIPITATION SHOULD
DEVELOP WEST OF THAT AREA. INSTABILITY AROUND THE LAKE LOOKS LIKE
IT WILL BE DEEP ENOUGH TO SUPPORT SOME LAKE ENHANCED PRECIP THIS
EVENING...BUT FLOW ALOFT WILL PROBABLY KEEP MOST OF THIS AWAY FROM
THE WASATCH FRONT.

SURFACE COLD FRONT AHEAD OF THE STORM SYSTEM IS NEAR A KELY-KPVU-
KVEL LINE AT THIS TIME. WINDS ARE PICKING UP AS THE PRESSURE
GRADIENT TIGHTENS OVER NORTHERN UTAH BEHIND THE FRONT...AND THIS
WILL CONTINUE THROUGHOUT THE DAY AS THE FRONT CONTINUES TO MOVE
SOUTHWARD...APPROACHING SOUTHERN UTAH BY THIS EVENING. WIND
ADVISORY REMAINS IN EFFECT UNTIL 6 PM TODAY FOR NORTHWESTERN
UTAH...THOUGH LOCAL WIND ADVISORY CONDITIONS ARE POSSIBLE IN THE
NORTHERN MOUNTAINS AS WELL.

PRECIPITATION AND WINDS WILL TAPER OFF TONIGHT AS THE STORM SYSTEM
MOVES EASTWARD OUT OF THE AREA. THIS WILL ALLOW DRIER NORTHWEST
FLOW TO BUILD IN BEHIND IT. WEAK RIDGING IS FORECAST TO DEVELOP
OVER THE STATE NEAR THE BEGINNING OF NEXT WEEK.

HAVE ISSUED AN UPDATE TO THE ZONES TO INCREASE WINDS OVER THE
NORTHERN MOUNTAINS. HAVE ALSO LOWERED POPS IN THE NORTHERN
MOUNTAINS AND DECREASED CLOUD COVER OVER THE NORTHERN VALLEYS THIS
MORNING TO REFLECT CURRENT TRENDS.

&&

.AVIATION...CLOUDS ARE EXPECTED TO DEVELOP THIS AFTERNOON WITH A 30
PERCENT PROBABILITY OF SHOWERS AND CEILINGS LOWERING BELOW 7000 FT.
THE MOST LIKELY TIME FOR THE LOWER CEILINGS OF ABOUT 5000-6000 FT IS
BETWEEN 21Z AND 02Z.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...SNOW ADVISORY UNTIL 8 PM FRIDAY FOR UTZ007.

     WIND ADVISORY UNTIL 6 PM FRIDAY FOR UTZ005.

WY...NONE.
