190 FXUS65 KSLC 252231 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 331 PM MST Tue Nov 25 2025 .SYNOPSIS...High pressure will bring dry conditions with a steady warming trend through Thanksgiving Day. Utah and southwest Wyoming will see more unsettled conditions Friday through the weekend with the potential for snow. && .DISCUSSION...Seeing mostly clear skies and light winds across Utah and southwest Wyoming this afternoon under the influence of high pressure centered off the California coast. The grazing storm system has moved well east of the area, but has brought a modest cooldown with highs running near seasonal normals across the area. The ridge will be the dominant weather feature across the area for much of the weak. It is expected to slowly shift east, with the axis moving overhead on Thanksgiving Day, forecast to be the most mild day of the week with maxes averaging 10F above seasonal normals. Confidence is high that the ridge will move east of the area Friday as a Pacific Northwest storm system makes its way onshore. About the details, however, confidence lowers significantly. This afternoon, the most common solution shows this initial system moving across northern portions of the area late Friday into early Saturday as a grazing system, resulting in a small chance of light snow for the mountains of northern Utah. Ensemble spread increases further with the trailing system behind the initial wave. A cut off over the Desert Southwest for Sunday is most favored, but a solution where this wave moves across northern Utah in a much more weakened state has gained some popularity. Overall, guidance is moving away from solutions that would produce more significant accumulations, so forecast snow totals have gone down significantly. High pressure is then likely to return early next week. && .AVIATION...KSLC...VFR conditions will prevail through the TAF period.
