AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1027 AM MST SUN NOV 7 2010

.SYNOPSIS...THE FIRST IN THE SERIES OF COLD AND WET STORM SYSTEMS
WILL REACH UTAH LATE TONIGHT. THIS STORM WILL AFFECT MUCH OF
THE STATE THROUGH EARLY TUESDAY. THE NEXT COLD PACIFIC STORM
SYSTEM WILL REACH UTAH LATE TUESDAY NIGHT...AND REMAIN OVER THE
AREA THROUGH WEDNESDAY NIGHT.

&&

.DISCUSSION...LATEST WATER VAPOR ANIMATION PUTS THE ERN PACIFIC
TROUGH SQUARELY ALONG 130W LATE THIS MORNING. THIS TROUGH STILL ON
TRACK TO MOVE INLAND AND INTO THE GREAT LATE LATER TONIGHT...THEN
ACROSS UTAH MONDAY/MONDAY NIGHT. THE LATEST MODEL GUIDANCE IN SO
FAR ALL INDICATING THE SAME BASIC SOLUTION...WHICH IS A TROUGH
WITH GOOD BAROCLINIC STRUCTURE PRODUCING A BROAD AREA OF
SYNOPTIC-SCALE LIFT LATE TONIGHT THROUGH EARLY TUESDAY.

ONE TREND IN THE GUIDANCE THE PAST COUPLE OF RUNS IS TO DEVELOP A
LITTLE LESS PRECIP OVER NRN/CNTRL UTAH. THIS TREND IN PART IS FROM
DRIER AND MORE STABLE AIR MOVING IN EARLY ON TUESDAY MORNING...AND
THE TROUGH ITSELF STRETCHING AND TAKING MORE OF THE DYNAMIC ENERGY
INTO SRN/CNTRL UTAH. THERE ARE OTHER SUBTLE ISSUES THAT WOULD
AFFECT OROGRAPHIC INFLUENCES...BUT THE BOTTOM LINE IS THAT
MOUNTAINS MAY SEE A LITTLE LESS SNOWFALL WITH AMOUNTS MORE IN THE
HIGH-END ADVISORY CRITERIA THAN HEAVY SNOW CRITERIA. FOR NOW WILL
STICK WITH THE WINTER STORM WATCH...THOUGH WILL PROBABLY OPT FOR
AN ADVISORY IN THE NRN MOUNTAINS IN THE AFTERNOON PACKAGE.

THE SURFACE TROUGH OVER CNTRL NV CREATING FAIRLY STRONG SOUTHERLY
WINDS OVER THE WRN VALLEYS LATE THIS MORNING. CONTINUED PRESSURE
FALLS AHEAD OF THE APPROACHING TROUGH AND FAIRLY WARM TEMPS OVER
UTAH INDICATE THAT WINDS WILL CONTINUE TO INCREASE THIS AFTERNOON.
LOOKING AT THE POSSIBILITY OF AN ADVISORY FOR MOST WRN VALLEYS
LATER THIS AFTERNOON UNTIL FRONTAL PASSAGE ON MONDAY. THE
STRONGEST WINDS MAY ACTUALLY OCCUR TONIGHT AHEAD OF ANY WIDESPREAD
PRE-FRONTAL PRECIP AND WHEN THE NEAR 700 MB WINDS PEAK AROUND THE
40-50 KT RANGE.

SHORTWAVE RIDGING LATE TUESDAY/TUESDAY NIGHT WILL BE FOLLOWED BY
THE NEXT COLDER PACIFIC TROUGH SCHEDULED TO ARRIVE IN THE BASIN
LATE TUESDAY NIGHT/WEDNESDAY. THE LATEST GFS AND THE 00Z ECMWF
SIMILAR IN MOST RESPECTS AS BOTH MODELS DRIVE THIS FEATURE HARD TO
THE S-SE INTO THE SRN ROCKIES BY EARLY THURSDAY. LOOKING AT A
FAIRLY WIDESPREAD PRECIP EVENT AHEAD OF THIS FEATURE...WITH FAIRLY
STRONG SUBSIDENCE BEHIND THE TROUGH SHUTTING DOWN MOST PRECIP.

WILL LIKELY ISSUE AN UPDATE SHORTLY TO ADDRESS STRONGER WINDS. THE
REMAINDER OF THE FORECAST LOOKS FINE FOR NOW.

&&

.AVIATION...GUSTY SOUTHERLY WINDS ARE EXPECTED TO HOLD AT THE KSLC
TERMINAL THROUGH TONIGHT...WITH SPEEDS OCCASIONALLY EXCEEDING
AIRPORT WEATHER WARNING CRITERIA OF 26KT. PRIMARY FOCUS IS TIMING OF
COLD FRONTAL PASSAGE AND LOWERING CEILINGS MONDAY MORNING. AT THIS
TIME LEANING TOWARDS A NORTHWEST WIND SHIFT BETWEEN 15-17Z TOMORROW
MORNING WITH OCCASIONAL PERIODS OF MVFR CEILINGS/VSBYS IN RAINFALL
FOR THE AFTERNOON HOURS.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WATCH FROM THIS EVENING THROUGH TUESDAY AFTERNOON
     FOR UTZ007>009.

WY...NONE.
