Washington – Headlights fade into gray just a few car lengths ahead as dense fog settles across the lowlands. Intersections feel quieter, and wet pavement reflects light back into the mist. Conditions remain hazardous during the morning commute.
According to the National Weather Service, a Dense Fog Advisory remains in effect across portions of western and northwest Washington until mid-morning. Visibility may drop to a quarter mile or less at times, especially near Puget Sound, river valleys, and low-lying roadways around Seattle, Everett, Tacoma, and Olympia.
Seattle drivers face the greatest impacts early, with fog thickest near shorelines and urban low spots. I-5, I-90, and Highway 99 may see sudden visibility drops. Slow speeds, increased following distance, and low-beam headlights are strongly advised. Pedestrians and cyclists should remain alert near crossings where drivers may have limited sightlines.
Fog gradually lifts late morning as sunshine breaks through. The afternoon turns calmer and brighter, with highs reaching the upper 50s. Friday stays mild and mostly sunny, offering a brief break before the weather shifts.
Rain returns Saturday and intensifies into Saturday night. Wet roads and reduced visibility combine again, though this time from steady rainfall rather than fog. Sunday remains damp and cool, with scattered showers lingering into early next week.
Nationally, meteorologists continue tracking an arctic blast gripping the Midwest and Northeast. While winter tightens its hold there, the Pacific Northwest trends milder in the 6–10 day outlook. Above-normal temperatures look increasingly likely by late next week, hinting at an early taste of spring.
