AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1030 AM MST SAT FEB 4 2006

.SYNOPSIS...THE NEXT PACIFIC STORM WILL SEND A COLD FRONT INTO UTAH
LATE TODAY AND THROUGH THE STATE TONIGHT. A COLD MOIST NORTHWEST FLOW
WILL BE OVER NORTHERN UTAH SUNDAY. HIGH PRESSURE ALOFT WILL RETURN
FOR NEXT WEEK.

&&

.DISCUSSION...MORNING WATER VAPOR IMAGERY AND OBJECTIVE ANALYSIS
DEPICT SHORTWAVE TROUGH TRANSLATING THROUGH PACIFIC NORTHWEST WITH
130KT JET STREAK LOCATED WITHIN BASE OF THIS TROUGH. TIGHT 700MB
BAROCLINIC ZONE ADVANCING ACROSS WESTERN ID/WESTERN NV WITH
ASSOCIATED SURFACE FRONT LOCATED NEAR OR/ID BORDER STRETCHING BACK
INTO FAR NORTHWEST NV TO THE NW OF KWMC...BASED ON SURFACE OBS AND
3-HOUR PRESSURE RISES ACROSS MUCH OF OR/NORTHERN CA. THIS TROUGH AND
ASSOCIATED JET STREAK WILL PROPAGATE THROUGH NORTHERN AND CENTRAL
UTAH THIS EVENING.

EXPECT THIS FRONT TO REACH THE WASATCH FRONT AROUND THE 01Z
TIMEFRAME. HOWEVER NAM/RUC BOTH SUGGEST 700/500 COLD ADVECTION TO
OVERSPREAD THE REGION AHEAD OF THIS FRONT. THIS MAY ALLOW SNOW
SHOWERS TO DEVELOP ACROSS THE HIGHER TERRAIN OF NORTHERN UTAH BY
LATE THIS AFTERNOON. EXPECT A BURST OF HEAVY PRECIPITATION
ALONG THE SURFACE FRONT EARLY THIS EVENING...ALONG WITH STRONG WIND
GUSTS POSSIBLY IN EXCESS OF 40 MPH ALONG THE WASATCH FRONT.
PRECIPITATION SHOULD TURN OVER TO SNOW WITHIN AN HOUR OR TWO OF
FROPA AS STRONG 700MB COLD ADVECTION SPREADS ACROSS THE AREA.
MOUNTAIN ZONES MAY SEE WIND GUSTS IN EXCESS OF 60 MPH WITH FROPA.
ADDITIONALLY MAY SEE A WEAK LAKE EFFECT EVENT LATE TONIGHT ACROSS
SOUTHERN SALT LAKE/EASTERN DAVIS COUNTIES. PROGGED 700MB TEMPS
AROUND -14C LATE TONIGHT COMBINED WITH LAKE TEMPS AROUND 1-2C ARE
MARGINALLY SUPPORTIVE FOR DEVELOPMENT OF LAKE BANDS. INSTABILITY
REMAINS ACROSS NORTHERN UT THROUGH MORNING HOURS SUNDAY BEFORE
WARMING ALOFT ASSOCIATED WITH SHORTWAVE RIDGE BUILDS ACROSS REGION
SUNDAY AFTERNOON.

HAVE GONE AHEAD AND ISSUED A SNOW ADVISORY FOR NORTHERN/CENTRAL
WASATCH FRONT AND WASATCH MOUNTAIN VALLEYS FOR THIS EVENING THROUGH
THURSDAY MORNING. MOST VALLEY LOCATIONS WILL LIKELY BE IN THE 1-3
INCH RANGE WITH 2-5 INCHES EXPECTED ALONG THE BENCHES. ADDITIONALLY
HAVE ISSUED A SNOW AND BLOWING SNOW ADVISORY FOR WASATCH AND WESTERN
UINTA MOUNTAINS TO ACCOUNT FOR COMBINATION OF SNOW AND STRONG WINDS
WITH FROPA.

LASTLY...MAY NEED TO ISSUE A WIND ADVISORY THIS AFTERNOON FOR
SOUTHWEST UT...AS WINDS ASSOCIATED WITH FROPA LATE TONIGHT...ALONG
WITH 700MB COLD ADVECTION AND NORTHERLY GRADIENT LATE TONIGHT
THROUGH SUNDAY MORNING...WILL SUPPORT GUSTY GAP WINDS.

&&

.AVIATION...RELATIVELY STRONG COLD FRONT WILL REACH SLC ABOUT 6PM
GIVE OR TAKE 1/2 HR. THERE IS ABOUT A 40 PERCENT CHANCE THAT
NORTHWEST WINDS COULD GUST TO 35-40 MPH WITH THE COLD FRONT. RAIN
SHOWERS WILL OCCUR WITH THE FRONT BUT WILL CHANGE OVER TO SNOW
BETWEEN 8 AND 9PM. SNOW WILL OCCUR TONIGHT WITH GENERAL IFR
CONDITIONS BUT TEMPORARY LIFR CONDITIONS ARE POSSIBLE BETWEEN 9PM
AND 12AM. SNOW ACCUMULATIONS OF 1-3 INCHES ARE EXPECTED BY SUNDAY
MORNING.
