EUGENE – A damp chill fills the air this Halloween morning as clouds hang low over the Willamette Valley, muting the early dawn light. Streets glisten from a night of mist, and a fresh round of rain looms just offshore — the next wave in Oregon’s quick turn toward a wet, early November.
According to the National Weather Service in Portland, rain chances climb through Saturday as a Pacific front pushes inland. After a mostly cloudy start Friday, precipitation becomes more widespread by late evening and continues through much of Saturday. Winds will pick up slightly, gusting near 20 mph during the heaviest periods of rain. Expect highs around the lower 60s Friday and dipping to the upper 50s by Saturday as cooler marine air settles in.
Saturday will bring the wettest stretch of the weekend, with models showing a 100% chance of measurable rain across Eugene and much of the southern Willamette Valley. Light accumulations are expected, but roads could turn slick — especially along Interstate 5 and rural corridors where leaves clog drains.
By Sunday, skies begin to clear. Partly sunny conditions and highs in the upper 50s will offer a short-lived break before another system brings additional rain by Monday.
Residents should prepare for wet commutes and consider clearing gutters ahead of next week’s storm track. After all, this is the Pacific Northwest’s signal that winter’s rhythm — gray mornings, steady rain, and cooling nights — has arrived for good.
