AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
106 PM MST SAT JAN 31 2026
KEY MESSAGES
- A STRONG AREA OF HIGH PRESSURE WILL BRING DRY AND STABLE
CONDITIONS THROUGH THE NEXT 7 TO 10 DAYS.
DISCUSSION...GOOD NEWS
BAD NEWS.
WE'LL START WITH THE GOOD NEWS. A STOUT UPPER LEVEL RIDGE AND REX
BLOCK WILL SET UP OVER THE NEXT 7 TO 10 DAYS ACROSS THE WEST. THE
GOOD NEWS IS THAT SEVERAL WEAK SHORTWAVE TROUGHS WILL EITHER
FLATTEN THE RIDGE AND PUSH WEAK COLD FRONTS THROUGH THE REGION OR
SHORTWAVE TROUGHS WILL TRY TO UNDERCUT THE RIDGE AND KEEP STRONG
VALLEY INVERSION FROM DEVELOPING. CORRESPONDINGLY, UTAH DEQ HAS
SEVERAL MONITORED NORTH BASINS INCLUDING THE SALT LAKE VALLEY
REMAINING AT YELLOW/MODERATE AIR QUALITY THROUGH MONDAY.
NOW THE BAD NEWS...WITH A STRONG RIDGE IN PLACE, EVEN WITH THESE
SHORTWAVE TROUGHS HELPING TO PREVENT STRONG INVERSIONS FROM
DEVELOPING, AN ANALYSIS OF VARIOUS ENSEMBLE SYSTEMS SHOWS A LESS
THAN 5% CHANCE OF MEASURABLE PRECIPITATION ACROSS NEARLY THE
ENTIRE STATE OF UTAH THROUGH NEXT SATURDAY. SOMEWHERE AROUND 50%
OF ENSEMBLE MEMBERS BREAK DOWN THE REX BLOCK AND BRING IN AT LEAST
0.01" OF PRECIPITATION ACROSS NORTHERN UTAH SUNDAY INTO MONDAY
(FEB 8-9), WITH AROUND 25% SHOWING MEASURABLE PRECIPITATION
ACROSS SOUTHERN UTAH.
AVIATION...KSLC
VFR CONDITIONS WILL PREVAIL WITH SCT-BKN HIGH-
LEVEL CLOUDS MOVING INTO THE AREA THIS AFTERNOON AND EVENING.
WINDS WILL REMAIN LIGHT AND TERRAIN-DRIVEN, WITH A GRADUAL
TRANSITION TO SOUTHEASTERLY BY 03-04Z.
REST OF UTAH AND SOUTHWEST WYOMING
VFR CONDITIONS WILL PREVAIL
IN MOST AREAS, WITH LIGHT, TERRAIN-DRIVEN WINDS. WHILE THE FOG
THREAT HAS DECREASED, THERE IS STILL A CHANCE OVERNIGHT AT KLGU
(30% CHANCE BETWEEN 11-17Z) AND IN THE EARLY MORNING AT KHCR (10%
CHANCE BETWEEN 12-16Z).
SLC WATCHES/WARNINGS/ADVISORIES
