Expires:No;;384172 FXUS66 KOTX 281719 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 919 AM PST Sun Dec 28 2025 .KEY MESSAGES... - Dry conditions through midweek then becoming unsettled late week into the weekend. && .SYNOPSIS... Dry and cold air remains over the region through Sunday. Temperatures moderate back to seasonal normals and dry conditions continue early next week, then a more active winter weather pattern returns heading into 2026. && .DISCUSSION... Today through Wednesday: Sunday will be the coolest day of the week as a departing system brought in cooler and drier Canadian air. High temperatures will reach into the 20s and 30s. The morning will start chilly in the single digits to low 20s. Although high pressure is building, there is a small chance (10-20%) of snow showers near the Cascade crest Sunday afternoon as moisture on the southern periphery of an atmospheric river moves into the region. Conditions look dry through the rest of the year (through Wednesday) as the ridge slowly shifts east. Temperatures begin to climb back above normal by Tuesday in the mid to upper 30s. Thursday through Sunday: Ensembles are in good agreement of troughing in the eastern Pacific by Thursday signaling the return of unsettled conditions. Precipitation amounts do not look overly impressive through late this week. There is only a 20-40% chance of 1.0" of liquid precipitation at the crest of the Cascades from Thursday to Sunday. For the Idaho Panhandle mountains, those chances decrease to 5-20%. The best chances for any lowland snow will be confined to near the Canadian border under this pattern. DB && .AVIATION... 18Z TAFs: Much drier air in place has resulted in widespread VFR conditions across eastern Washington and north Idaho. As an upper level ridge shifts into the Pacific Northwest today, moisture associated with weather systems moving into British Columbia will stream in from the northwest. There is high confidence for passing mid and high level clouds, but conditions are expected to remain VFR. Winds are expected to generally remain light through the period, though an increasing easterly pressure gradient will result in east to southeast winds up to 10 knots at KPUW late Sunday morning and evening. .FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence for widespread VFR conditions. ----------------------- 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...
