AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
917 AM MST FRI NOV 15 2013

.SYNOPSIS...THE FIRST OF TWO STORM SYSTEMS WILL CROSS THE AREA
TODAY. A SECOND STRONGER SYSTEM WILL IMPACT MAINLY NORTHERN UTAH
LATE TONIGHT THROUGH SATURDAY NIGHT. HIGH PRESSURE ALOFT WILL
RETURN FOR THE FIRST HALF OF NEXT WEEK.

&&

.DISCUSSION...
WATER VAPOR LOOP SHOWS THE ELONGATED DISTURBANCE APPROACHING FROM
THE NORTHWEST. ACARS 400-250MB WIND OBSERVATIONS SHOW A 80KT-110KT
WESTERLY JET OVER THE DESERT SOUTHWEST. GOES/GPS/RAP/12Z SLC RAOB
ALL INDICATE THE PRECIPITABLE WATER RANGES BETWEEN 0.15" AND 0.50".

LOOKS LIKE A EUROPEAN/GFS COMPROMISE WORKED OUT FOR THIS MORNING.
THE SYSTEM IS SLOWER AND MORE SPLIT THAN THE EUROPEAN PORTRAYED YET
NOT ENOUGH SO TO LIMIT EXTENT OF PRECIPITATION ACROSS NORTHERN UTAH
LIKE THE GFS INDICATED. THIS PRECIPITATION WILL DIMINISH AS THE
SHEARED WAVE CROSSES THE REGION THIS AFTERNOON. HOWEVER SHOWERS
EXPECTED TO DEVELOP ACROSS EAST CENTRAL AND SOUTHEAST UTAH GIVEN
BUILDING INSTABILITY SHOWN BY 09Z SHORT RANGE ENSEMBLES AND
PROXIMITY TO THE AFOREMENTIONED UPPER LEVEL JET.

RAISED POPS BASED ON WHATS ALREADY OCCURRED AND ABOUT TO TRANSLATE
SOUTHEAST. ADJUSTED SKY COVER TO BE MORE OPTIMISTIC FOR SOUTHWEST
UTAH WHERE ITS SUNNY.

AFTERNOON PACKAGE WILL FOCUS ON TRENDS FOR TOMORROWS SYSTEM.

PREVIOUS DISCUSSION FOLLOWS...
THE FIRST OF TWO MID-LEVEL TROUGHS TO IMPACT UTAH EXTENDS FROM
SOUTHWEST MONTANA TO NORTHEAST NEVADA EARLY THIS MORNING. THE
LEADING NEAR 700MB BAROCLINIC ZONE AHEAD THIS FIRST FEATURE HAS
BECOME THE FOCUS OF LIGHT TO LOCALLY MODERATE PRECIP ACROSS FAR
NORTHERN UTAH OVER THE PAST HOUR. THIS PRECIP WILL LIKELY INCREASE
IN INTENSITY AND SPREAD SOUTH INTO CENTRAL UTAH DURING THE MORNING
AS DYNAMIC LIFT AND LOW/MID-LEVEL COLD ADVECTION INCREASE WITH THE
PASSAGE OF THE UPPER TROUGH. PRECIP-TYPES IN THE VALLEYS ARE
BOUNCING BETWEEN RAIN AND SNOW AT THIS TIME...THOUGH SUSPECT SNOW
WILL BECOME THE MORE PREVALENT PRECIP-TYPE UP NORTH AS PRECIP
INTENSITIES INCREASE AND COLD AIR CONTINUES TO POUR SOUTH INTO THE
AREA. CENTRAL UTAH VALLEYS WILL LIKELY STAY IN RAIN...THOUGH MORE
INTENSE PRECIP COULD COME AS SNOW FOR A BRIEF PERIOD.

A BRIEF BREAK IN PRECIP BEHIND THE EXITING FIRST TROUGH WILL BE
SHORT-LIVED AS THE NEXT SYSTEM MOVES QUICKLY TOWARDS NORTHERN UTAH.
THE LEADING EDGE OF THE NEXT ROUND OF PRECIP WILL ARRIVE LATE
TONIGHT...AND WILL BE THE RESULT OF DEEP LAYER AND MOIST WARM
ADVECTION ACROSS FAR NORTHERN UTAH. HEAVY SNOW A GOOD BET OVER THE
NORTHERN MOUNTAINS ON SATURDAY AS THE MID-LEVEL TROUGH REACHES
NORTHERN UTAH/EASTERN IDAHO. DEEP LAYER MOISTURE/INSTABILITY
WORKING WITH THE TROUGH DYNAMICS WILL LEAD TO WIDESPREAD PRECIP
ACROSS THE NORTHERN THIRD OF UTAH/SOUTHWEST WYOMING...WITH
OROGRAPHIC ENHANCEMENT BOOSTING SNOW TOTALS ACROSS THE NORTHERN
WASATCH RANGE. THE FAVORABLE SYNOPTIC SITUATION ALONG WITH A
FAIRLY LONG DURATION TO THE EVENT HAS LED TO THE ISSUANCE OF A
SNOW/BLOWING SNOW ADVISORY FOR THE NORTHERN WASATCH RANGE
BEGINNING LATE TONIGHT THROUGH SATURDAY NIGHT. THIS ADVISORY WILL
LIKELY BE EXPANDED TO OTHER MOUNTAIN LOCATIONS AS THIS SYSTEM
PUSHES PRECIP FURTHER SOUTH AND EAST SATURDAY. NORTHERN VALLEY
LOCATIONS MAY ALSO BE INCLUDED WITH TIME...WITH THE NORTHERN WASATCH
FRONT AND CACHE VALLEY THE MOST LIKELY CANDIDATES.

SOUTHERN AND CENTRAL UTAH LOOK AS IF THEY WILL MISS OUT ON THE
BULK OF THIS SECOND STORM AS THE MAIN TROUGH WILL TURN EAST
THROUGH SOUTHERN WYOMING/NORTHERN COLORADO SATURDAY NIGHT. THIS
TURN TO THE EAST WILL ALSO RESULT IN RAPIDLY BUILDING HEIGHTS AND
WARMING ALOFT SUNDAY. LINGERING INSTABILITY SHOWERS WILL EXIST
OVER NORTHERN UTAH EARLY SUNDAY...WITH THESE SHOWERS ENDING SUNDAY
AFTERNOON.

HIGH PRESSURE MOVES IN RAPIDLY BEHIND THE EXITING SUNDAY TROUGH. THE
EC IS A LITTLE FASTER AND STRONGER THAN THE GFS WITH THE BUILDING
RIDGE BUT THE RESULTING SENSIBLE WEATHER SHOULD BE RELATIVELY
SIMILAR FOR MONDAY AND TUESDAY. THE HIGHER ELEVATIONS WILL SEE A
RAPID WARMING THESE DAYS BUT THE VALLEYS WILL ONCE AGAIN BE TRAPPED
UNDER A STRONG INVERSION. THIS INVERSION MAY BREAK A LITTLE TUESDAY
DUE TO AN INCREASE IN CLOUD COVER MONDAY NIGHT BUT WITH THE MODELS
SHOWING A THICKENING PLUME OF CLOUDS ON TUESDAY THIS MAY NOT RESULT
IN MUCH DIFFERENCE FOR MAXIMUM TEMPERATURES.

BY MID WEEK THE GFS IS FASTER WITH BRINGING IN A WEAK SYSTEM WITH
THE EC ABOUT 24 HRS SLOWER AND THE GEM HALFWAY IN BETWEEN. ALTHOUGH
THIS IS A WEAKER SYSTEM WITH RELATIVELY MILD H7 TEMPS THERE APPEARS
TO BE MORE OF A SUB TROPICAL CONNECTION DUE TO THE TRAJECTORY OF
THIS SYSTEM MOVING IN FROM THE WEST RATHER THAN THE NORTHWEST. THE
GEFS ENSEMBLE MEAN BRINGS IN 0.50 TO 0.60 OF AN INCH PW MIDWEEK
WHICH IS A COUPLE OF TENTHS GREATER THAN THIS WEEKEND'S STORM. IN
ADDITION THE NAEFS PROBABILITY OF QPF GREATER THAN 0.01 OF AN INCH
IS 20 TO 40 PERCENT ACROSS MUCH OF THE CWA FROM 12Z WEDNESDAY TO 00Z
FRIDAY. ALTHOUGH HAVE LITTLE EXPERIENCE WITH THE ACCURACY OF THIS
PROG DECIDED TO LEAN TOWARDS CLIMO POPS FOR CENTRAL AND NORTHERN
UTAH IN LIGHT OF THE ABOVE PW AND NAEFS FORECAST. WITH H7 TEMPS
GENERALLY WARMER THAN -5C THROUGH THE PERIOD THERE SHOULD BE NO
ISSUES FOR SNOW IN THE VALLEYS WITH THIS SYSTEM BUT COLD ENOUGH FOR
SNOW DOWN TO ABOUT 5500-6500 FT ESPECIALLY THURSDAY IN THE NORTH.

&&

.AVIATION...A QUICK MOVING SYSTEM WILL CONTINUE THROUGH THE AREA
THIS MORNING. OCCASIONAL RAIN SHOWERS OR RAIN/SNOW MIX WILL CONTINUE
AT THE SLC TERMINAL THROUGH 17-19Z THIS MORNING. CEILINGS ARE
EXPECTED TO REMAIN BELOW 3000 FEET AGL THOUGH AT LEAST 18Z BEFORE
IMPROVING TO NEAR 5000 FEET AGL FOR MOST OF THE AFTERNOON. A FEW
SHOWERS MAY MOVE THROUGH THE VICINITY OF THE AIRPORT AFTER
18Z...BRIEFLY DECREASING CEILINGS BACK TO MVFR LEVELS TEMPORARILY.

UTAH AND SOUTHWEST WYOMING THIS MORNING. WIDESPREAD VALLEY RAIN AND
SNOW...WITH ACCUMULATING SNOW ARE EXPECTED THIS MORNING. HIGH
ELEVATION ROADWAYS ACROSS NORTHERN UTAH...INCLUDING THE FAR NORTHERN
VALLEYS...COULD SEE A COUPLE INCHES ACCUMULATION THIS MORNING.

PRECIPITATION WILL SWING SOUTH INTO CENTRAL UTAH LATER THIS

IS EXPECTED. VALLEYS WILL SEE PRIMARILY RAIN...THOUGH BRIEF PERIODS
OF SNOW ARE POSSIBLE IN HEAVIER PRECIPITATION.

TEMPERATURES WILL BE SUBSTANTIALLY COLDER TODAY VERSUS THURSDAY.
READINGS ACROSS THE NORTH COULD DROP BY 10 TO 15 DEGREES TODAY...
WITH A FEW DEGREES OF COOLING EXPECTED ACROSS THE SOUTHERN HALF OF
THE STATE.

A BREAK IN RAIN AND SNOW THIS EVENING WILL BE SHORT-LIVED AS THE
NEXT STORM SYSTEM REACHES FAR NORTHERN UTAH LATE TONIGHT. STRONG
WINDS AND INCREASINGLY HEAVY SNOWFALL IS EXPECTED ACROSS THE
NORTHERN WASATCH RANGE LATE TONIGHT. A WINTER WEATHER ADVISORY FOR
SNOW AND BLOWING SNOW HAS BEEN ISSUED FOR THAT PORTION OF THE
OUTLOOK AREA.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THE SECOND STORM TO IMPACT UTAH WILL REACH ITS PEAK INTENSITY
AND AREAL COVERAGE ACROSS THE NORTHERN THIRD OF UTAH SATURDAY.

WEEKEND STORM. TEMPERATURES WILL CONTINUE THE DOWNWARD TREND AS
COLDER DOES PUSH SOUTH INTO SOUTHERN UTAH. STRONG SOUTHWEST WINDS
WILL DEVELOP ACROSS FAR SOUTHERN AND EASTERN UTAH SATURDAY AS THE
STORM SYSTEM MOVES ACROSS THE NORTHERN HALF OF THE OUTLOOK AREA.

HIGH PRESSURE ALOFT WILL RETURN EARLY NEXT WEEK. THIS HIGH WILL
BRING ABOUT A GRADUAL WARMING TREND AND DRY CONDITIONS EARLY IN TH
WEEK. A WEAK WEATHER DISTURBANCE COULD RETURN LIGHT PRECIPITATION TO
THE FAR NORTH MIDWEEK.
