AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1019 AM MST WED NOV 25 2015

.SYNOPSIS...A COLD UPPER LOW WILL SETTLE INTO THE GREAT BASIN
TODAY. THIS LOW WILL CONTINUE TO IMPACT THE AREA THROUGH THE
THANKSGIVING WEEKEND.

&&

DISCUSSION...BROAD UPPER LOW CURRENTLY CENTERED OVER NORTHWEST
NEVADA WILL CONTINUE TO SLOWLY ROTATE INTO UTAH TONIGHT...THEN
LINGER IN THE VICINITY THROUGH THE WEEKEND. THE ASSOCIATED COLD
FRONT IS CURRENTLY SITUATED OVER NORTHWEST UTAH.
MEANWHILE...PRECIPITATION HAS FILLED IN EVEN AHEAD OF SAID BOUNDARY
GIVEN UPPER DIFFLUENCE ASSOCIATED WITH THE UPPER JET NOSING INTO
NORTH-CENTRAL UTAH. ON THE OTHER HAND...MUCH OF SOUTHERN/EASTERN
UTAH REMAINS MOSTLY CLEAR AT THIS TIME. EXPECT PRECIPITATION TO
INCREASE THROUGHOUT THE DAY AS THE FRONT SLOWLY PUSHES THROUGH THE
REGION.

SNOW IS ALREADY BEING REPORTED ACROSS PORTIONS OF WESTERN UTAH...FOR
EXAMPLE NEAR WENDOVER. SOME PORTIONS OF NORTHERN UTAH...MAINLY NEAR
THE IDAHO BORDER...ARE STILL SEEING TEMPERATURES IN THE 30S AND MAY
FAIL TO MIX WELL BEFORE PRECIPITATION INCREASES. AS A RESULT...THESE
AREAS COULD SEE MOSTLY SNOW AND ACCUMULATIONS COULD END UP BEING A
BIT MORE PRODUCTIVE THAN FORECAST. OTHERWISE...GENERALLY LIGHT
ACCUMULATIONS THROUGH THIS AFTERNOON ARE EXPECTED IN MOST VALLEYS
WITH SOME RAIN INITIALLY BELOW 6000-6500FT BEFORE CHANGING TO SNOW.

BESIDES THE PRECIPITATION...SOME GUSTY WINDS ARE EXPECTED TODAY
AHEAD OF AND IMMEDIATELY BEHIND THE FRONT. THE STRONGEST WINDS
SHOULD BE ACROSS SOUTHERN UTAH THROUGH THIS AFTERNOON.

FOR THIS EVENING AND OVERNIGHT...PRECIPITATION MOSTLY IN THE FORM OF
SNOW WILL CONTINUE MAINLY ACROSS NORTHERN ZONES. THE GREATEST SNOW
ACCUMULATIONS WILL OCCUR IN NORTHERN UTAH AND SOUTHWEST WYOMING
OVERNIGHT AND INTO TOMORROW MORNING. WILL HAVE TO REVIEW WHETHER
HIGHLIGHTS NEED TO BE ADJUSTED...BUT THEY SEEM FINE FOR NOW. ALSO
WILL HAVE TO SEE ABOUT POSSIBLE STRONG CANYON/DOWNSLOPE WINDS FOR
THE WASATCH FRONT. FOR TONIGHT...THERE COULD BE ENHANCED CANYON
WINDS AS MODELS START TO INCREASE AN EASTERLY GRADIENT ACROSS THE
AREA...BUT STRONGER WINDS ARE EXPECTED TOMORROW NIGHT AS 700MB FLOW
AND COLD ADVECTION BECOMES BETTER ALIGNED.

MADE SEVERAL UPDATES TO MORNING PACKAGE FOR TODAY...WITH THE
GREATEST ADJUSTMENTS TO TEMPERATURES AND SKY.

&&

.AVIATION...SOUTHERLY WINDS EXPECTED TO BECOME GUSTY BETWEEN 18 AND
19Z WITH GUSTS EXCEEDING 30 MPH AT THE SLC TERMINAL. WINDS WILL
SHIFT TO THE SW OR EVEN W BETWEEN 21-23Z. THERE IS A 30 PERCENT
CHANCE THAT WINDS WILL SHIFT TO WNW BY 21-22Z DUE TO PREFRONTAL
OUTFLOW. CIGS WILL REMAIN ABOVE 7K FT AGL THROUGH ABOUT 21-22Z THEN
LOWER AS PRECIP DEVELOPS WITH A CHANCE OF MVFR CONDITIONS AFTER 23Z.

&&
