AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
811 AM MST TUE NOV 6 2012

.SYNOPSIS...HIGH PRESSURE WILL REMAIN OVER THE REGION THROUGH
WEDNESDAY. A LARGE AND RATHER COLD PACIFIC STORM SYSTEM WILL REACH
THE GREAT BASIN BY FRIDAY...AND REMAIN OVER THE AREA THROUGH MUCH
OF THE UPCOMING WEEKEND.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS A RIDGE BUILDING INTO THE
INTERIOR WEST. ACARS SHOWS A 75-140KT ANTICYCLONICALLY CURVED JET
FROM WESTERN CANADA INTO THE PLAINS. RUC...GOES...GPS SENSORS...AND
12Z KSLC RAOB INDICATE PRECIPITABLE WATER VALUES ARE IN THE
0.15"-0.50" RANGE ACROSS THE REGION.

GOING FORECAST IS IN GOOD SHAPE. A FEW MID AND HIGH CLOUDS CONTINUE
TO SPILL INTO NORTHERN UTAH THIS MORNING. AS THE RIDGE BUILDS
IN...EXPECT THIS TO DIMINISH THROUGHOUT THE DAY. A CONTINUED WARMING
TREND IS FORECAST TODAY AS 700MB TEMPERATURES WARM ANOTHER DEGREE OR
TWO C. WINDS ARE GENERALLY LIGHT TODAY...EXCEPT NEAR CANYONS THROUGH
MID MORNING.

THE FOCUS WITH THE AFTERNOON PACKAGE WILL BE WINDS AHEAD OF THE
STORM AND SNOW ACCUMULATION POTENTIAL HEADING INTO THE WEEKEND.

PREVIOUS DISCUSSION FOLLOWS...
THE UPPER RIDGE SQUARELY OVER THE INTERIOR WEST THIS MORNING LOOKS
TO GUARANTEE UNSEASONABLY WARM TEMPS ACROSS THE ENTIRE FORECAST AREA
THROUGH WEDNESDAY. A FEW HIGH TEMPS RECORD COULD FALL
WEDNESDAY...WITH THE MOST LIKELY AREAS BEING THE WESTERN VALLEYS
WHERE SOME MIXING COULD DEVELOP DURING THE AFTERNOON.

THE MAJOR CHANGE TO THE PATTERN ADVERTISED OVER THE PAST SEVERAL
MODEL RUNS IS STILL ON TRACK FOR THE END OF THE WEEK. THE COLD
CORE UPPER TROUGH STILL SITUATED OVER THE GULF OF ALASKA WILL TAKE
A TURN TO THE SOUTHEAST AND POSITION OFF THE PACIFIC NORTHWEST
COAST BY EARLY THURSDAY. FROM THERE THE TROUGH WILL ELONGATE
NORTH-TO-SOUTH AND ENCOMPASS MUCH OF THE WESTERN CONUS FRIDAY
THROUGH SATURDAY.

THE LEADING COLD FRONT WILL REACH INTO EXTREME NORTHWEST UTAH LATE
THURSDAY NIGHT. THIS FRONTS ARRIVAL HAS BEEN GETTING PUSHED BACK
WITH EACH SUBSEQUENT MODEL RUN OWING TO THE DEEPENING OF THE
PARENT TROUGH. THIS MAKES SENSE...AND WOULD NOT BE SURPRISED IF
THE FRONT ACTUALLY HOLDS OFF ENTERING UTAH UNTIL LATE THURSDAY
NIGHT OR EARLY FRIDAY MORNING. INITIALLY THIS FRONT MAY NOT
GENERATE MUCH CONVECTIVE PRECIP AS THE MID-LEVEL COLD AIR HOLDS
BACK IN NEVADA WITH THE MAIN TROUGH. FAIRLY STRONG LOW-LEVEL
FRONTOGENETIC FORCING MAY OVERCOME THE LACK OF DEEP-LAYER
INSTABILITY AND MOISTURE...BUT ANY PRECIP WILL FOR THE MOST PART
WILL REMAIN LIGHT.

WIDESPREAD PRECIP...MOSTLY IN THE FORM OF SNOW...WILL DEVELOP
ACROSS THE FORECAST AREA FOR LATE FRIDAY THROUGH SATURDAY NIGHT.
DEEP LAYER MOISTURE AND COLD AIR INSTABILITY WILL PEAK SATURDAY
THROUGH SATURDAY EVENING. THIS FAVORABLE MOISTURE AND THERMAL
SUPPORT COMBINED WITH DYNAMIC LIFT WITHIN THE MAIN TROUGH WILL
OFFER THE BEST PERIOD FOR ORGANIZED SNOWFALL THIS WEEKEND.
OROGRAPHIC ENHANCEMENT OF SNOWFALL MAY BECOME A PLAYER ACROSS
NORTHERN AND CENTRAL UTAH. THE ECMWF APPEARS TO BE THE MORE
FAVORABLE MODEL FOR THIS TYPE OF EVENT AS IT ADVERTISES A MORE
PERSISTENT DEEP LAYER CYCLONIC WEST-NORTHWEST FLOW DURING THE DAY
SATURDAY.

THE LATEST GFS AND ECMWF ARE NOW LOCKED IN ON THE MORE CONSISTENT
ECMWF SOLUTION FOR LATE IN THE WEEKEND. BOTH MODELS NOW EJECT THE
TROUGH AXIS EAST OF THE STATE BY SUNDAY AFTERNOON...WITH RAPID
MID-LEVEL WARMING/DRYING BRINGING A QUICK END TO CONVECTION DURING
THE MID TO LATE AFTERNOON. VERY COLD TEMPS WILL FOLLOW SUNDAY
NIGHT WITH VALLEY FOG A REAL POSSIBILITY BY MONDAY MORNING. A
SHORTWAVE RIDGE DEVELOPING ACROSS THE REGION EARLY IN THE WEEK WILL
KEEP PRECIP AT BAY AND ALLOW TEMPS TO CLIMB OUT OF THE VERY COLD
WEEKEND TEMPS.

&&

.AVIATION...OPERATIONAL WEATHER CONCERNS WILL REMAIN MINIMAL AT THE
KSLC TERMINAL THROUGH THE VALID TAF PERIOD. SOUTHEAST SURFACE WINDS
WILL SHIFT TO THE NORTHWEST BETWEEN 18-20Z...VFR CONDITIONS WILL
HOLD.

&&

.DAY ONE...TODAY AND TONIGHT

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

WEDNESDAY WILL BE THE WARMEST DAY FOR MANY DAYS TO COME. HIGH
PRESSURE ALOFT ACROSS THE GREAT BASIN WILL ALLOW TEMPERATURES TO
CLIMB TO READINGS WELL ABOVE EARLY NOVEMBER NORMS. RECORD HIGH
TEMPERATURES ARE A POSSIBILITY.

A VERY COLD AND ENERGETIC PACIFIC STORM SYSTEM WILL MOVE INTO THE
REGION BY EARLY FRIDAY. AHEAD OF THIS STORM A STRONG COLD FRONT WILL
CROSS NEVADA THURSDAY....THEN ENTER NORTHWEST UTAH EITHER LATE
THURSDAY NIGHT OR EARLY FRIDAY. THIS FRONT WILL MOVE ACROSS THE
AREA FRIDAY...BRINGING AN END TO WARM TEMPERATURES AND GENERATING
WIDESPREAD PRECIPITATION FOR MAINLY THE NORTHERN AND CENTRAL PORTIONS
OF UTAH THROUGH MUCH OF THE UPCOMING WEEKEND.

MOST OF THE PRECIPITATION WITH THIS STORM WILL COME IN THE FORM OF
SNOW. SIGNIFICANT ACCUMULATIONS ARE POSSIBLE IN THE NORTHERN AND
CENTRAL MOUNTAINS...ALONG WITH THE ADJACENT VALLEYS OF WESTERN AND
NORTHERN THROUGH SOUTHWEST WYOMING. THE HEAVIEST SNOWFALLS ARE
LIKELY ON SATURDAY THROUGH SATURDAY EVENING. SNOW WILL GRADUALLY
TAPER OFF LATE SATURDAY NIGHT THROUGH SUNDAY MORNING.

HIGH TEMPERATURES THAT HAD BEEN 10 TO 20 DEGREES ABOVE NORMAL WILL
NOT COME IN AT 10 TO 20 DEGREES BELOW NORMAL THIS WEEKEND. LOW
TEMPERATURES BOTH SUNDAY AND MONDAY MORNINGS WILL GENERALLY DROP
INTO THE TEENS AND 20S...WITH SINGLE DIGIT READINGS IN THE MOUNTAINS
