933 FXUS66 KOTX 260535 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1035 PM PDT Wed Sep 25 2024 .SYNOPSIS... Scattered showers and breezy winds will continue overnight. Temperatures return to near normal by Thursday with another cold front passage Friday. Above average temperatures return Saturday into early next week, with Saturday the warmest day of the weekend. Some freezing overnight lows are possible again heading into next week. && .DISCUSSION... Evening update: Weather conditions are calming down from earlier today as the cooler, maritime air mass settles into the region. With the higher humidity, lower wind speeds, and some precipitaiton...blowing dust no longer poses a widespread risk and we have ended the blowing dust advisory. Winds are also decreasing but not calm by any means. Localized gusts 30-40 mph will remain possible for the next few hours as the upper-level trough swings inland and cold air advection continues. This will also keep a threat for showers and a few lightning strikes into the overnight hours. && .AVIATION... 06Z TAFS: Cooler upper-level trough is tracking into the region and will promote elevated winds through morning. Pullman has recently decoupled and added wind shear but this comes with low confidence and could see increasing surface winds overnight. Bands of light showers will pass through with the best chance coming across far SE WA, North Idaho, and the northern mountains. A Puget sound convergence zone will also impact the Cascade crest between Hwy 2 and I-90. Clouds with this activity will expand into Wenatchee but any precip will mainly be confined to Leavenworth to Stevens Pass. Otherwise, majority of the region will experience VFR skies with lighter winds on Thursday.. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate confidence in VFR conditions for much of the region. The one uncertainty will be a small shield of MVFR ceilings developing between Pullman and Spokane. HREF gives this a 20% of occurring. && .PRELIMINARY POINT TEMPS/POPS...
