989 FXUS65 KSLC 100958 AFDSLC 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. && .AVIATION...KSLC...VFR conditions expected at the terminal through the TAF period.
