SCHEDULED TO MOVE THROUGH THE REGION BEGINNING EARLY IN THE
UPCOMING WEEK.

.DISCUSSION...THE COLD CORE UPPER TROUGH CURRENTLY OVER THE
PACIFIC NORTHWEST WILL TRACK GENERALLY TO THE EAST ACROSS THE
NORTHERN ROCKIES/NORTHERN GREAT BASIN LATER TODAY/TONIGHT. THE
SOUTHERN END OF THIS TROUGH WILL GRAZE THE NORTHERN THIRD OF UTAH
TODAY. THE ASSOCIATED AND WELL-DEFINED SURFACE COLD FRONT WILL
REACH THE NORTHWEST CORNER OF UTAH EARLY THIS MORNING. STRONG BUT
RELATIVELY SHALLOW COLD ADVECTION WILL PUSH THIS SURFACE FEATURE
RAPIDLY SOUTHEAST THROUGH THE STATE TODAY. PRECIP WILL LIKELY LAG
BACK ACROSS THE FAR NORTH NEAR THE DEEP LAYER COLD AIR/MOISTURE
AND MODEST DYNAMIC LIFT ASSOCIATED WITH THE UPPER TROUGH. DO NOT
SEE ANY REAL THREAT FOR PRECIP BEYOND CENTRAL UTAH AS THE FRONTAL
LIFT WILL BE SHALLOW AND THE AIRMASS QUITE DRY.
WINDS WILL LIKELY BE THE BIGGEST ISSUE WITH TODAYS WEATHER
DISTURBANCE. STRONG NEAR 700 MB WINDS AND A TIGHT SURFACE GRADIENT
BEHIND THE SURFACE FRONT SIGNALS A RAPID INCREASE IN TRIALING
WEST-NORTHWEST WINDS THIS MORNING. FAR NORTHWEST UTAH WILL BE
PRONE TO STRONG WINDS TODAY...AND HAVE ISSUED A WIND ADVISORY FOR
THE NORTHWEST DESERTS/MOUNTAINS. CONSIDERED AN HIGH WIND
WARNING...BUT WITH THE FRONT PASSING EARLY IN THE DAY AND THE

THIS WINTER A SPLIT TROUGH MOVING INTO THE WESTERN CONUS LATE

GREAT BASIN MONDAY...THEN SLOWLY GRIND EAST ACROSS THE BASIN
MONDAY NIGHT THROUGH TUESDAY. THIS FEATURE LOOKS TO BE A GOOD SNOW
PRODUCER WITH DEEP LAYER COLD AIR/MOISTURE AND SYNOPTIC-SCALE LIFT
FROM THE UPPER LOW. SOLID LIFT AND THE RELATIVELY SLOW EASTWARD
MOVEMENT OF THIS FEATURE SHOULD ALLOW FOR SUBSTANTIAL SNOWFALL IN
THE MOUNTAINS AND FAVORED VALLEY LOCATIONS THROUGH TUESDAY EVENING.
SHORTWAVE RIDGING WEDNESDAY WILL BE FOLLOWED BY A BROAD UPPER
TROUGH ACROSS THE NORTHERN ROCKIES THROUGH AT LEAST THE NORTHERN
AND CENTRAL GREAT BASIN FOR THE END OF THE WEEK. FOCUS OF PRECIP
