AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
258 AM MST MON NOV 10 2025
SYNOPSIS
HIGH PRESSURE WILL BRING DRY AND MILD CONDITIONS TO
UTAH AND SOUTHWEST WYOMING THROUGH MIDWEEK. WINDS WILL PICK UP
WEDNESDAY INTO THURSDAY AHEAD OF THE NEXT APPROACHING STORM
SYSTEM, EXPECTED TO IMPACT THE AREA FRIDAY INTO THE WEEKEND.
DISCUSSION
HIGH PRESSURE IS CENTERED OVER THE GREAT BASIN THIS
MORNING, BRINGING DRY AND TRANQUIL CONDITIONS TO UTAH AND
SOUTHWEST WYOMING. SOME HIGH CLOUDS ARE MOVING INTO NORTHERN UTAH
AND SOUTHWEST WYOMING, WITH CLEAR SKIES ELSEWHERE. UNDER THE
INFLUENCE OF THE RIDGE, TEMPERATURES WILL CONTINUE TO WARM WITH
MAXES GENERALLY RUNNING 5-10F ABOVE SEASONAL NORMALS. TEMPERATURES
WILL CONTINUE TO TREND UPWARD A BIT THROUGH WEDNESDAY, THOUGH
DEVELOPING INVERSIONS MAY LIMIT WARMING IN SOME VALLEY LOCATIONS
AND ALLOW FOR POLLUTANTS TO ACCUMULATE.
BY WEDNESDAY, THE RIDGE AXIS IS EXPECTED TO SHIFT EAST OF THE AREA
AS A BROAD STORM SYSTEM APPROACHES THE PACIFIC COAST. THIS WILL
BRING INCREASING SOUTHWEST FLOW AND THUS INCREASING WINDS
WEDNESDAY INTO THURSDAY. WITH THE PEAK OF THE WINDS THURSDAY
AFTERNOON, LATEST ENSEMBLE GUIDANCE IS INDICATING BETWEEN A 40 AND
70 PERCENT CHANCE OF WIND GUSTS IN EXCESS OF 45 MPH FOR WIND PRONE
AREAS OF WEST CENTRAL AND SOUTHWEST UTAH, SOMETHING TO MONITOR
GOING FORWARD.
CONFIDENCE IS HIGH THAT THE AREA WILL SEE SOME IMPACTS FROM THE
PACIFIC STORM SYSTEM AS IT MOVES ACROSS THE AREA FRIDAY INTO THE
WEEKEND. STILL SEEING SIGNIFICANT ENSEMBLE SPREAD, HOWEVER, IN
THE TIMING AND TRACK OF THE SYSTEM, IMPACTING THE POTENTIAL FOR
PRECIPITATION. A LOT OF THE UNCERTAINTY IS IN REGARD TO WHETHER OR
NOT THE SYSTEM CLOSES OFF OR MOVES THROUGH AS A PROGRESSIVE OPEN
WAVE, WITH THE LATTER SCENARIO BRINGING MUCH COLDER TEMPERATURES
TO THE AREA AND A GREATER POTENTIAL FOR SIGNIFICANT PRECIPITATION.
