Oregon – Mist clings to streetlights along the Willamette Valley as dawn pushes through a dim, silver sky. Wet pavement reflects early headlights, and the air feels thick with the scent of damp leaves. Even this quiet start hints at an unfolding November pattern that could complicate errands, commutes, and early holiday travel along I-5 from Creswell to Junction City.
The National Weather Service in Portland notes a slight chance of showers early today, followed by brief clearing and a mild high near 62. To be fair, today offers the most comfortable conditions before the pattern turns wetter. Residents planning leaf cleanup, market runs, or short trips should use the morning dryness. Light rain returns later this afternoon, and a more organized push of moisture develops tonight with a 30 percent chance of rain.
Saturday brings increasing clouds and another round of scattered showers, especially after 4 p.m. Calm winds limit mixing, allowing patchy fog to form across low-lying farmland east of town. By Sunday, the real soaking arrives. A stronger plume of Pacific moisture funnels into the valley, producing 80 to 90 percent rain coverage. Expect ponding on rural roads, slow-moving traffic near campus areas, and reduced visibility where fog and rain overlap.
Models even hint at a “Winter Tease” next week as colder air approaches the Cascades. While Eugene stays too warm for flakes, higher passes could see early mixed precipitation—something Thanksgiving travelers should watch closely.
After all, mid-November often introduces Oregon’s most persistent cloudy stretches, and this weekend marks that transition.
