WYOMING WILL TAPER OFF OVERNIGHT AS A STORM SYSTEM EXITS THE
AREA, BUT SOME SHOWERS WILL LINGER OVER THE HIGHER TERRAIN AND
SOUTHWEST WYOMING TUESDAY MORNING.

DISCUSSION
A STORM SYSTEM IS CENTERED IN THE VICINITY OF
SOUTHWEST WYOMING THIS EVENING, BRINGING WIDESPREAD PRECIPITATION
THERE AND TO NORTHERN UTAH. SNOW LEVELS HAVE PRIMARILY BEEN IN THE
6,500 TO 7,000 FOOT RANGE, BUT IN HIGHER RATES HAVE BEEN SEEN SNOW
IN PARTS OF THE CACHE VALLEY AS WELL AS THE BENCHES OF WEBER
COUNTY, WITH LITTLE IN THE WAY OF ACCUMULATION. THE SYSTEM AND
ASSOCIATED COLD FRONT WILL EXIT OVERNIGHT, WITH ASSOCIATED
PRECIPITATION DECREASING IN COVERAGE SIGNIFICANTLY OVER THE NEXT
FEW HOURS. SOME SHOWERS WILL LINGER OVER SOUTHWEST WYOMING AS WELL
AS THE HIGHER TERRAIN INTO TUESDAY MORNING.
HIGH PRESSURE WILL BRIEFLY MOVE IN BEHIND THE EXITING SYSTEM FOR
LATE TUESDAY INTO MUCH OF WEDNESDAY, BRINGING DRY CONDITIONS AND A
RETURN OF VERY MILD TEMPERATURES. MAXES WEDNESDAY ARE ON TRACK TO
RUN 10-15F ABOVE SEASONAL NORMALS, A THEME THAT HAS BEEN COMMON
THIS COOL SEASON.
A PACIFIC NORTHWEST STORM SYSTEM IS EXPECTED TO MOVE ONSHORE
DURING THE DAY WEDNESDAY, BEFORE CROSSING THE FORECAST AREA EARLY
THURSDAY INTO FRIDAY. OVERALL TIMING IN THE GUIDANCE IS A BIT
SLOWER THAN WHAT WAS INDICATED THIS TIME YESTERDAY, WITH MOST
MEMBERS ALLOWING THE SYSTEM TO LINGER A BIT LONGER AS IT CLOSES
OFF. MODELS CAN HAVE A BIT OF TROUBLE WITH THE DETAILS OF SYSTEMS
THAT ARE CLOSING OFF, SO TIMING OF THE END OF PRECIP WITH THIS
SYSTEM IS A BIT MORE UNCERTAIN THAN USUAL. GIVEN ITS PACIFIC
NORTHWEST ORIGIN, IT WILL BE COLDER IN NATURE THAN THE LAST
SYSTEM, BRINGING TEMPERATURES TO OR BELOW NORMAL FOR THIS TIME OF
YEAR, AND A CHANCE OF ACCUMULATING SNOW TO NORTHERN UTAH VALLEY
FLOORS, WITH THE BEST CHANCE IN THE CACHE VALLEY AND STILL ONLY A
LOW CHANCE FOR THE WASATCH FRONT. IT IS LOOKING INCREASINGLY
LIKELY THAT MOUNTAIN TOTALS COULD BE SIGNIFICANT, RESULTING IN
SOME TRAVEL DIFFICULTIES. THOSE WITH TRAVEL PLANS IN THE HIGHER
TERRAIN SHOULD CONTINUE TO MONITOR THE FORECAST.
ONCE THE SYSTEM EXITS, DRIER CONDITIONS ARE EXPECTED FOR THE
UPCOMING WEEKEND WITH TEMPERATURES STARTING TO WARM AGAIN. THERE
REMAIN SOME INDICATIONS OF A RETURN TO UNSETTLED CONDITIONS BY
EARLY NEXT WEEK, WITH VERY LOW CONFIDENCE IN ANY DETAILS.
AVIATION...KSLC
COOL AND MOIST SYSTEM WILL DEPART THROUGH THE
OVERNIGHT, WITH PRECIPITATION GRADUALLY TAPERING OFF. WINDS WILL
LIKELY HAVE SOME PERIODS OF VARIABILITY OWING TO THE PRECIPITATION.
CIGS WILL TEND TO SIT AROUND 10-25 KFT FOR MUCH OF THE NIGHT BEFORE
GRADUALLY LIFTING AND SCATTERING OUT IN THE HOURS FOLLOWING SUNRISE.
WINDS WILL THEN FAVOR RETURNING TO A DIURNALLY NORMAL PATTERN WITH
SKIES BECOMING MOSTLY CLEAR.
REST OF UTAH AND SOUTHWEST WYOMING
A COOL SEASON SYSTEM WILL
DEPART THROUGH THE NIGHT, WITH PRECIPITATION AT NORTHERN TERMINALS
GRADUALLY TAPERING OFF. CIGS/VIS WILL LEAN IFR TO MVFR, WITH THE
MOST DEGRADED CONDITIONS EXPECTED AT THE FAR NORTHERN AND HIGHER
ELEVATED TERMINALS WHERE SNOW CAN MIX IN OR PREVAIL. THROUGH MID TO
LATE MORNING TUESDAY, CIGS WILL THEN GRADUALLY LIFT AND SCATTER OUT,
WITH A RETURN TO WIDESPREAD VFR CONDITIONS ANTICIPATED LATE MORNING
TO EARLY AFTERNOON AT MOST TERMINALS.
