Dec 17, 2025 – Winds ease across western Washington as a cooler, more seasonal pattern settles; forecasters note “winds ease, cooler pattern takes hold” and predict 5‑10 inches of snow at Snoqualmie and Stevens Pass, while an atmospheric river brushes the region bringing about half an inch of rain to lowlands and 1‑2 inches to the mountains, raising concerns for urban flooding, landslides, and power outages[10].

Dec 20, 2025 – Heavy mountain snow returns ahead of Christmas, with Stevens Pass topping 18 inches and Snoqualmie Pass around 10 inches; officials warn that “travel conditions likely to worsen Sunday evening” and advise drivers to avoid Sunday night travel as cumulative totals could reach 1 foot at lower passes and 2‑3 feet at Mount Baker and Paradise by early next week[9].

Dec 27, 2025 – Light snow lingers in the Puget Sound convergence zone into Saturday morning, depositing up to 2 inches in Snohomish and King counties while mountain passes receive 10‑14 inches; a ridge brings a dry, cold‑night pattern through Monday, with a new system expected late Wednesday or Thursday to bring “gradual warming of a few degrees”[7].

Dec 27, 2025 – The National Weather Service issues a Winter Weather Advisory for Cascade passes, noting snow levels dropping to ~2,500 ft on Friday and forecasting 6‑12 inches of snow across Snohomish, King, Whatcom and Skagit counties; travelers are urged to “check weather before traveling Saturday” and to carry emergency kits per WSDOT guidance[8].

Jan 8, 2026 – A colder system pushes snow levels down to about 1,500 ft by Wednesday and as low as 500 ft overnight, creating spotty lowland wet‑snow and slick roads; despite limited accumulation at sea level, the Cascades remain under a Winter Storm Warning with 2‑4 feet of additional snow expected, prompting “wet, slippery roads rather than significant snowfall” warnings[6].

Jan 29, 2026 – Cascade snowpack remains far below normal despite recent snowfall, with Stevens Pass gaining only 2‑3 inches and Snoqualmie Pass 1‑2 inches; Oregon’s snowpack sits at its second‑lowest level since 1981, and SNOTEL data show deep deficits in central and southern Cascades, raising concerns for spring streamflow and water resources[5].

Feb 17, 2026 – Snow levels drop to about 500 ft Wednesday morning, allowing low‑elevation wet‑snow and a rain‑snow mix from the Kitsap Peninsula to coastal foothills; meteorologist Rich Marriott says “a mixed precipitation type could affect” these areas, while weather anchor Parella Lewis notes that “overall effect on lowland communities should remain limited,” though slick roads may develop during breaks in precipitation[4].

Feb 18, 2026 – Statewide snowpack sits at roughly 65 % of normal, with Snoqualmie Pass at only 40 % of typical depth, threatening summer water supplies; the article links the “dry winter” to past El Niño‑linked seasons of 1976‑77, 1980‑81 and 2014‑15, and notes a 50‑60 % chance of a weak El Niño next winter, which could influence fire risk and ski tourism[3].

Feb 21, 2026 – Forecast calls for increasing rain and lowland snow Saturday, with a Wind Advisory for the Cascade Foothills and North/Central Coast through 10 a.m. Sunday as gusts reach 40‑50 mph; multiple fronts driven by an offshore low will deliver rain, sleet, wet snow and breezy conditions through the week, and models predict “several feet of mountain snow by the end of next week” while lowland temperatures rise to the low 50s[2].

Feb 22, 2026 – A week‑long storm sequence brings rain, snow, and gusty easterly winds (40‑50 mph) from the weekend through next week, with snow levels climbing to 2,000‑2,500 ft then 3,500 ft and falling to 2,500‑3,000 ft by mid‑week; forecasters warn that “multiple feet of mountain snow and 1‑3 inches of rain at lower elevations by week’s end” are expected and urge residents to stay updated on evolving conditions[1].
