FXUS66 KOTX 082042 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 142 PM PDT Wed Jul 8 2026 .KEY MESSAGES... - Critical Fire Weather: Red Flag Warnings in effect Wednesday due to gusty winds and low relative humidity. - Elevated fire weather conditions through the weekend. && .SYNOPSIS... Critical fire weather conditions will continue through Wednesday evening for central and eastern Washington. Weather will remain and dry through the week with breezy afternoon winds. This will keep fire weather conditions elevated through the weekend. && .DISCUSSION... Wednesday night through Sunday: A cold front traversing the Inland Northwest is resulting in dry and breezy conditions this afternoon and evening. Critical fire weather conditions will continue across much of central and eastern Washington through the evening. Winds will gradually weaken tonight across most areas, though breezy conditions will persist in the lee of the Cascades. Through early Friday, the region will remain under a zonal flow aloft, situated south of an upper- level trough over western Canada. Diurnal marine pushes into western Washington will tighten the cross- Cascade pressure gradient daily, driving enhanced evening winds through the Cascade gaps. As a result, elevated fire weather conditions will persist for the next couple of days, particularly through the Cascade gaps of the Cascades, due to the combination of low relative humidity and breezy winds. By late Friday, upper-level flow shifts southwesterly as a closed low migrates southeastward along the British Columbia coast and a ridge builds over the Desert Southwest. This pattern will keep temperatures warm across the Inland Northwest under the subtle influence of the ridge. On Saturday, the upper-level low along the BC coast low is projected to track northeastward, with winds increasing aloft, and generating more widespread breezy conditions during the afternoon and evening. This will bring continued elevated fire weather concerns, with the highest confidence (60-90% probability) for sustained winds exceeding 15 mph and relative humidity dropping below 20% focused in the Okanogan Valley. Monday through Thursday: Uncertainty in the synoptic pattern increases significantly next week with respect to additional systems coming off the Pacific and how far north the upper-level ridge will amplify into the Inland Northwest. If the arrival of the next system is as early as Monday night, this will stunt amplification into the INW, with temperatures remaining similar to the weekend and a risk of thunderstorms early in the week. If the Pacific systems are delayed until the Wednesday or Thursday timeframe, this would allow the upper-level ridge to build into the INW, with temperatures warming significantly and a risk for thunderstorms by mid-week. During the Tuesday to Thursday timeframe, there is a 7 to 11 degree spread between the 25th and 75th percentiles for maximum temperatures in the NBM, highlighting this uncertainty. /vmt && .AVIATION... 18Z TAFs: A cold front moving through the Inland Northwest will bring dry and gusty winds across the region today. Flight conditions are expected to remain VFR today. Winds have begun to increase with southwesterly to westerly gusts generally between 20 to 25 knots. The windiest location will be in the lee of the Cascades, particularly at KEAT where gusts 28 to 32 knots are expected this afternoon into the early evening. Winds will remain breezy at KEAT through the night with winds at KMWH weakening around 06Z. Winds will relax across other TAF sites around 01-03Z. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence for VFR conditions regionwide. ----------------------- Confidence descriptors: Low - Less than a 30percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...
