242 FXUS65 KSLC 031846 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 1146 AM MST Mon Nov 3 2025 .SYNOPSIS...Mild temperatures and dry conditions are expected across the region through midweek. Southwesterly flow will increase on Wednesday ahead of a series of weak systems which will impact northern Utah and southwest Wyoming Thursday into Saturday. Strong high pressure will build in by early next week. && .DISCUSSION...High pressure is centered over Colorado today, putting Utah and southwest Wyoming under a southwest flow aloft. A weak shortwave embedded in the flow is crossing the area, with high and mid level clouds clearing out as it exits. Temperatures will stay on the mild side today, with maxes running around 10F above seasonal normals. Northern Utah will see an increase in cloud cover and moisture tomorrow as a weakening Pacific Northwest trough moves well north of the area. Otherwise, conditions will stay dry and mild. The flow will pick up across the area during the day Wednesday as a stronger Pacific Northwest storm system moves onshore. Conditions will be breezy across the area, with a low (30-40%) chance of wind gusts in excess of 40 mph Wednesday afternoon for the normally wind prone areas of west central and southwest Utah. The system is expected to graze northern portions of the area Wednesday night into Thursday, bringing enough moisture and instability for precipitation over far northern Utah, with the greatest chance occurring near the Utah/Idaho border. Given the progressive and disorganized nature of the system, associated mountain accumulations will be light at best. The cold front with the system is expected to cross the area through Thursday morning. The change in temperature will be most noticeable for northern portions of the area, with maxes most likely returning to near normal for this time of year by Thursday afternoon. For southern Utah, maxes are expected to generally run up to 5F above climo. After ridging makes a brief return, a second (and weaker) system is on track to graze northern Utah Friday night into Saturday, keeping maxes near climo and bringing a very small chance of some precipitation over far northern Utah. Beyond that, strong ridging is expected to build over the Great Basin through day seven and beyond, bringing dry and stable conditions with the potential for valley inversions. && .AVIATION...KSLC...VFR conditions are expected to persist at KSLC through the TAF period. Northwest winds will continue this afternoon with a south-southeasterly shift arriving around 02-04z this evening. Later in the period, BKN upper level cloud arrive as a storm system draws near. .REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected to persist across the majority of our sites. Lighter, diurnal winds will occur across most sites with the exception of KEVW and KCDC where enhanced southwesterlies will develop this afternoon with gusts to around 20-25kts, dissipating by sunset. && .SLC WATCHES/WARNINGS/ADVISORIES...
