894 FXUS66 KOTX 240544 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 944 PM PST Fri Jan 23 2026 .KEY MESSAGES... - Colder temperatures this weekend with overnight lows in the teens to low 20s - Quiet weather pattern through next week - Temperatures moderating for the middle to end of next week && .SYNOPSIS... Colder temperatures are expected this weekend with overnight lows in the teens to lower 20s. A quiet weather pattern is expected through next week. && .DISCUSSION... Tonight through Sunday: A drier northerly flow is expected to bring a continued trend of clearing skies heading into the weekend. This will result in colder overnight low temperatures in the teens to low 20s. There are a couple initial exceptions to the clearing, with one area being the Cascade valleys in Chelan county, as well as the Palouse/LC Valley where it is taking longer for the dry air to mix down. Higher resolution models do hang onto some boundary layer moisture into Saturday morning for these two areas which is expected to lead to continued areas of stratus, as well as patchy freezing fog overnight into Saturday morning. But eventually the dry air should win out as precipitable water values hover around 40-60 percent of normal through the weekend. Monday through Friday: Ensembles show a split flow pattern with incoming weak fronts stretching and falling apart as they track into Eastern Washington and North Idaho. Thus precipitation chances are low through the week, with a 20-30% chance limited to near the Cascade crest and ID Panhandle mountains starting on Wednesday. These weak systems however will help moisten the low levels as the lower level flow switches from north to west and southwest. This has the potential to bring some increase in boundary layer moisture with areas of low clouds and fog during the overnight and morning hours. Although at the same time the passing mid level clouds will help mitigate this, leading to overall low confidence in precise mixing heights and air stagnation potential next week. Longer range outlook going into the first week of February heavily favors a mild weather pattern. Thus for the next two weeks the outlook for both lowland and mountain snow looks bleak. JW && .AVIATION... 06Z TAFs: While dry air has resulted in clear skies across most TAF locations, the boundary layer will moisten through the TAF period, leading to high scattered and broken decks by 09Z. MWH, EAT, and LWS look to remain at VFR status through the next 24 hours. A stratus deck has lingered around KPUW and has filled in further, dropping ceilings to IFR and anticipated to stay that way through much of the TAF period until 03Z, when ceilings will improve to MVFR. Enough models show visibilities dropping for PUW that BR and FZFG were put in starting at 12Z, and will improve by 17Z. With boundary layer moisture remaining throughout the day, models pick up on lowered ceilings for GEG, SFF, and COE tomorrow morning just after this TAF period ends. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Alternate scenario is that the stratus lingering around PUW will move into the GEG area and bring down ceilings for a few hours this morning, but confidence is low on this. Moderate confidence in continued VFR conditions for all sites but PUW. Another alternate scenario is stratus filling in enough to lower ceilings for LWS, though this is also low confidence. /AS ----------------------- Confidence descriptors: Low - Less than a 30 percent 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...
