AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
852 PM MST TUE FEB 16 2016

.SYNOPSIS...HIGH PRESSURE WILL WILL SHIFT EAST WEDNESDAY AHEAD OF
THE NEXT PACIFIC STORM SYSTEM...WHICH IS EXPECTED TO ARRIVE ON
THURSDAY. TRANQUIL WEATHER WILL RETURN FRIDAY INTO NEXT WEEKEND.

&&

.DISCUSSION...ANOTHER QUIET NIGHT IS IN STORE FOR UTAH AS THE AXIS
OF AN UPPER-LEVEL RIDGE MOVES INTO THE AREA. A FEW HIGH CIRRUS
CLOUDS WILL DRIFT THROUGH THE RIDGE...BUT OTHERWISE MOSTLY CLEAR
SKIES CAN BE EXPECTED. AS SUCH...WASATCH MOUNTAIN VALLEY LOCATIONS
SUCH AS HEBER CITY COULD SEE ANOTHER ROUND OF PATCHY FOG TONIGHT.
SOME EARLY-MORNING FOG IS POSSIBLE IN THE CACHE VALLEY AS WELL.
OTHERWISE...THE ATTENTION TURNS TO A BRIEF BUT POTENT WEATHER
DISTURBANCE AND ASSOCIATED COLD FRONT LINING UP FOR LATE
WEDNESDAY NIGHT INTO THURSDAY. THE BIG IMPACT WILL LIKELY BE WINDY
CONDITIONS FOR CENTRAL AND NORTHERN UTAH VALLEYS...ALONG WITH A
QUICK BURST OF HEAVY SNOW FOR THE HIGHER ELEVATIONS.

.PREVIOUS DISCUSSION...ISSUED 356PM MST...

AS THE AFOREMENTIONED RIDGE SHIFTS EAST TOMORROW A STRENGTHENING
SOUTHWESTERLY FLOW ALOFT COMBINED WITH A GRADUAL TIGHTENING OF A
SE-NW MSLP GRADIENT IN ADVANCE OF THE TROUGH WILL ALLOW FOR
BREEZY SOUTHERLIES ACROSS THE WESTERN VALLEYS. THIS COUPLED WITH
CONTINUED WAA ALOFT SHOULD ALLOW DEEP MIXING OF THE AIR MASS AND
A FURTHER UPTICK IN TEMPS TOMORROW. OPTED TO RAISE TEMPS MANY
AREAS AND NOW HAVE LOW 60S FOR SOME AREAS ALONG THE WASATCH FRONT
INCLUDING THE SALT LAKE METRO AREA.

FOCUSING ON THE TROUGH...TWO PIECES TO NOTE WITH THE LATTER
BRINGING THE MOST NOTABLE CHANGE SENSIBLY ON THURSDAY...BUT THE
WEAKER /AT LEAST STRUCTURALLY/ INITIAL WAVE WEDNESDAY NIGHT WILL
BRING THE FIRST INCREASE OF SW WINDS ALOFT AND SCATTERED PRECIP
ACROSS THE NORTH. REGARDING THESE WINDS...MODELS CONTINUE TO
SUGGEST A RAPID INCREASE OF H7 FLOW WITH 50-60 KNOTS BECOMING THE
NORM AFTER MIDNIGHT WEDNESDAY NIGHT. WITH FURTHER TIGHTENING OF
THE MSLP IN PLACE...INCREASED CLOUD CLOVER AND SPOTTY PRECIP
COINCIDENT...ANTICIPATE SOME MIXING OF THIS FLOW ACROSS THE
WESTERN VALLEYS WITH MINIMAL DECOUPLING OF THE BOUNDARY LAYER.
OUTSIDE OF POTENTIAL NEED FOR WIND HIGHLIGHTS TOMORROW
NIGHT...CONFIDENT IN VERY WARM TEMPS MOST ALL AREAS WITH MID 40S
LOWS LIKELY MANY WESTERN VALLEYS. THIS WAVE WILL PASS EARLY
THURSDAY MORNING ALLOWING FOR SOME CLEARING...THOUGH WINDS WILL
CONTINUE TO BE ON THE RISE THROUGH THE MORNING AHEAD OF THE MAIN
WAVE AND ATTENDANT COLD FRONT.

THE PARENT TROUGH WILL BECOME NEGATIVELY TILTED THURSDAY MORNING
WITH A VERY PROGRESSIVE ENE TRAJECTORY ACROSS THE EASTERN GREAT
BASIN ON INTO THE NORTHERN ROCKIES. MODELS CONTINUE TO DEPICT
MODEST FRONTOGENESIS ALONG THE COLD FRONT OVER WESTERN UTAH LATE
THURSDAY MORNING INTO THE EARLY AFTERNOON. GFS/ECMWF CONTINUE TO
DEPICT FRONTAL PASSAGE AROUND 11AM ALONG THE I-15
CORRIDOR...LIKELY PACKING VERY STRONG POST FRONTAL WINDS. THOUGH
STRONG FORCING WILL DRIVE WIDESPREAD PRECIP WITH SNOW LEVELS
LIKELY FALLING BRIEFLY TO VALLEY FLOORS LATE MORNING/AFTERNOON...VALLEY
IMPACTS WILL LIKELY BE MOST NOTABLE FROM THE PRE/POST FRONTAL
WINDS. IN THE MOUNTAINS AND MOUNTAIN VALLEYS ADVERSE CONDITIONS
ARE EXPECTED DUE TO BRIEF HEAVY SNOW AND GUSTY WINDS WITH IMPACTS
FROM BOTH. LIKELY WILL NEED WIND HIGHLIGHTS FOR THE WESTERN VALLEYS
AND WINTER HIGHLIGHTS IN THE MOUNTAINS AND POTENTIALLY MOUNTAIN
VALLEYS FOR SHORT DURATION INTENSE SNOWFALL AND STRONG/GUSTY
WINDS IN COMING SHIFTS.

PROGRESSIVE NATURE OF TROUGH WILL ALLOW FOR RAPID IMPROVEMENT
THURSDAY EVENING WITH DIMINISHING WINDS AND DRYING CONDITIONS.
TEMPS MUCH COLDER BEHIND THE FRONT. TRANQUIL WEATHER IS EXPECTED
FOR FRIDAY.

.LONG TERM (AFTER 00Z SATURDAY)...A FAIRLY BENIGN PATTERN IS
EXPECTED FOR THE LONG TERM PORTION OF THE FORECAST. RIDGING WILL BE
IN PLACE ACROSS THE INTERIOR WEST FRIDAY AFTERNOON. AT THE SAME
TIME...A SPLITTING TROUGH IS EXPECTED TO BE NEAR THE NORTHWEST
PACIFIC COAST. WHILE THE RIDGE WILL FLATTEN IN RESPONSE TO THIS
TROUGH PASSING THROUGH THE NORTHERN INTERMOUNTAIN REGION LATER
FRIDAY INTO SATURDAY...THE SHORTWAVE WILL REMAIN WELL DISPLACED FROM
THE CWA. MUCH OF THE 00Z MODEL GUIDANCE IS NOW IN AGREEMENT WITH
THIS TRAJECTORY. THIS WOULD LIMIT ANY CHANCE OF PRECIPITATION WITH
THE PASSING OF THIS WAVE TO THE NORTH TO A FEW SHOWERS IN THE
MOUNTAINS.

EXPECT ANOTHER PERIOD OF RIDGING TO BUILD INTO THE AREA FOR THE
WEEKEND AND INTO EARLY NEXT WEEK...WHICH IS SUPPORTED BY A MAJORITY
OF THE 00Z MODEL GUIDANCE. THE MAIN TAKEAWAY MESSAGE IS THERE IS
LITTLE THREAT OF PRECIPITATION FOR THE LONG TERM PORTION OF THE
FORECAST WITH TEMPERATURES NEAR TO A BIT ABOVE NORMAL.

&&

.AVIATION...SOUTHERLY WINDS WILL PREVAIL THROUGH THE TAF PERIOD
WITH WINDS INCREASING MID MORNING WEDNESDAY AND THEN RAMPING UP TO
MODERATE TO STRONG LEVELS BY AFTERNOON. NO VSBY OR CIG ISSUES
WITHIN THIS TAF PERIOD. A STRONG COLD FRONT WILL SWING THROUGH THE
AREA BY THURSDAY MORNING.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
