AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
434 PM MST TUE JAN 17 2012

.SYNOPSIS...A SERIES OF EMBEDDED WEATHER DISTURBANCES IN THE MOIST
WESTERLY FLOW ACROSS THE NORTHERN GREAT BASIN WILL GENERATE
SUBSTANTIAL PRECIPITATION ACROSS NORTHERN UTAH THROUGH THE WEEKEND.
A STRONGER SYSTEM LATE IN THE WEEKEND WILL BRING PRECIPITATION TO
THE REMAINDER OF UTAH SUNDAY THROUGH EARLY MONDAY.

&&

.DISCUSSION...THE MOIST WESTERLY FLOW ALOFT SETTING UP ACROSS THE
NORTHERN GREAT BASIN PROMISES TO GENERATE WIDESPREAD PERIODIC AND
RATHER SUBSTANTIAL PRECIPITATION ACROSS THE NORTHERN HALF OF UTAH
AND SOUTHWEST WYOMING WEDNESDAY THROUGH THE UPCOMING WEEKEND. THE
ONE GIVEN IN THIS PATTERN IS THAT THE NORTHERN MOUNTAINS...
PARTICULARLY THE WASATCH RANGE...WILL SEE PERIODS OF HEAVY SNOW
WITH ACCUMULATIONS LIKELY MEASURING IN FEET THROUGH SUNDAY. THE
STRONG WESTERLIES USHERING IN THE EMBEDDED SHORTWAVE WILL ALSO
PRODUCE STRONG RIDGETOP WINDS THROUGHOUT THE MOUNTAINS. WINTER
STORM WARNINGS HAVE BEEN ISSUED FOR THE NORTHERN MOUNTAINS...WITH
THE WESTERN UINTAS PROBABLY RECEIVING A LITTLE LESS SNOW THAN THE
WASATCH RANGE. HAVE NOT ISSUED ANY HIGHLIGHTS FOR SOUTHWEST
WYOMING AS OF YET...THOUGH SUSPECT THAT SUFFICIENT SNOW AND WIND
WILL EXIST FOR SOME KIND OF WINTER WEATHER HIGHLIGHTS BY WEDNESDAY
NIGHT...OR THURSDAY AT THE LATEST.

THE CONCERN THAT HAS EXISTED FOR AWHILE...AND STILL PLAGUES THE
FORECAST...IS THE EXPECTED PRECIP TYPE THROUGH THE DURATION OF
THIS STORM CYCLE. MODEL BUFR SOUNDINGS FROM TODAYS MODEL RUNS ARE
POINTING TOWARDS A PERIOD OF SNOW LATE WEDNESDAY THROUGH WEDNESDAY
EVENING FOR THE CENTRAL AND SOUTHERN WASATCH FRONT...MAINLY SALT
LAKE CITY SOUTHWARD. SUFFICIENT MIXING BY LATE WEDNESDAY NIGHT OR
EARLY THURSDAY SHOULD TURN SNOW TO RAIN...OR A RAIN/SNOW MIX BY
THURSDAY AFTERNOON. CONFIDENCE OF THIS CHANGE IS FAIRLY HIGH AT
THIS POINT BASED ON THE AVAILABLE MODEL DATA...AND THE FACT THAT
THE COLD AIR FROM THIS MORNING APPEARS TO HAVE MIXED OUT
REASONABLY WELL THIS AFTERNOON.

THE NORTHERN WASATCH FRONT AND CACHE VALLEY ARE THE AREAS WHERE
FAR LESS CONFIDENCE EXISTS CONCERNING PRECIP TYPE. MIXING ALSO
TAKING PLACE THIS AFTERNOON IN THOSE AREAS...THOUGH NOT QUITE AS
EFFICIENTLY AS FURTHER SOUTH. SUSPECT THAT AS PRECIP DEVELOPS
ON WEDNESDAY...THIS PRECIP WILL START AS SNOW NORTH OF THE OGDEN/
BRIGHAM CITY AREA DUE TO FAIRLY LARGE TEMP/DEW POINT DEPRESSIONS.
ANY TRANSITION TO RAIN OR A RAIN/SNOW MIX WILL LIKELY STAY ON THE
WEST SIDE OF THE WASATCH RANGE...LEAVING THE CACHE VALLEYS...AND
THE BEAR LAKE VALLEY TO THE EAST IN SNOW. STILL HAVE A GREAT DEAL
OF UNCERTAINTY AT THIS POINT IN TIME...SO WILL MAINTAIN THE CURRENT
WINTER STORM WATCH AS IS IN THE AFTERNOON PACKAGE.

SOUTHERN AND CENTRAL UTAH WILL BECOME INVOLVED IN THIS STORM CYCLE
FOR A BRIEF TIME LATER IN THE WEEKEND. SHORTWAVE ENERGY EMBEDDED
IN THE WESTERLIES ARE FORECAST TO GAIN SOME AMPLIFICATION AS THEY
MOVE THROUGH THE BASIN DURING THE WEEKEND. THE LAST SYSTEM IN THE
WEEKEND SERIES WILL OFFER THE BEST THREAT LATE SUNDAY/EARLY MONDAY
AS THIS LAST FEATURE WILL DIG SOUTHEAST INTO THE SOUTHERN HALF OF
THE GREAT BASIN. HIGH PRESSURE ALOFT WILL FOLLOW FOR THE MID-WEEK
PERIOD...WITH THE POTENTIAL FOR ACTIVE WESTERLIES AGAIN LATE NEXT
WEEK.

&&

.AVIATION...SOUTHERLY WINDS WILL CONTINUE OVERNIGHT AT THE SLC
TERMINAL...WITH THESE WINDS BECOMING INCREASINGLY LATE TONIGHT
THROUGH EARLY WEDNESDAY. VFR CONDITIONS ARE EXPECTED AS INCREASING
CLOUD COVER WILL REMAIN ABOVE 12 KFT THROUGH EARLY WEDNESDAY
MORNING.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WATCH FROM WEDNESDAY AFTERNOON THROUGH THURSDAY
     AFTERNOON FOR UTZ001-002-005.
