Oregon — Fog clings to the valley floor this morning, drifting between neighborhoods and softening the glow of early headlights. The pavement carries a cool sheen, and the damp November air feels dense against the foothills east of Eugene. These are the subtle signs of another active stretch of Pacific moisture building offshore, the type of pattern that often leads to steady rain by the end of the weekend.

Residents should prepare now for shifting conditions that may affect early Thanksgiving travel. Even patchy fog can slow traffic along I-5, especially between Eugene and Albany. Drivers heading toward the coast on Highway 126 should watch for sudden visibility drops near the river corridor. Adding time to morning schedules will help avoid delays as the weather shifts.

Today brings a quieter window, with only a slight chance of early rain before clouds give way to some filtered sun. It’s a useful day for outdoor errands or late-fall yard cleanup before wetter days return. To be fair, this break won’t last long. Models hint at a Winter Tease pattern taking shape—cooler nights, thick clouds, and repeated rounds of valley rain.

Rain increases Saturday night, and Sunday brings the most impactful system in this stretch. Moderate rainfall and light southeasterly winds will push through much of the day. New rainfall could reach between a quarter and half an inch, enough to create wet roads, slower traffic, and small ponding in familiar low spots around Eugene and Springfield.

Monday keeps the pattern going with more rain likely through midday. Drivers should expect slower speeds on the morning commute, especially near construction zones and merging ramps.

A brief break returns Tuesday before another round of showers approaches Wednesday and Thursday as Thanksgiving week ramps up.
