Oregon – Mist clings to windshields this morning as a gray curtain settles over Eugene, softening the hills and turning every traffic light into a blurred glow. Pavement stays wet, and light drizzle deepens quickly—an early signal that a soggy stretch will dominate travel through the next several days.
According to the National Weather Service, rain builds steadily today, strengthening by late morning as a moist Pacific plume pushes into the Willamette Valley. Precipitation chances reach 100%, with showers turning widespread and occasionally heavier by afternoon. Drivers along I-5, Route 126, and neighborhood arterials should prepare for ponding, muted visibility, and longer braking distances.
Rain continues through Friday as south winds increase to 9 mph, with gusts near 20 mph during peak rounds. While temperatures hold in the upper 40s to mid-50s, the consistent moisture keeps roads slick and crosswalks slippery. After all, even light rainfall can hide deeper water pockets under leaves and low drainage points.
Saturday brings another strong chance of rain, and conditions may deteriorate fastest near the evening commute when a new band pushes inland. Keep jackets and umbrellas close and expect slower travel on bridges and ramps where wind and spray reduce visibility.
Meteorologists are also tracking early signs of winter shifts nationally. Long-range models continue suggesting bands of lake-effect snow from December 11–17, especially across Michigan, Ohio, Pennsylvania, and New York. Anyone connecting through Midwest airports should prepare for delays or re-routing as Arctic air deepens.
Locally, Eugene remains locked in a mild but very wet pattern through early next week, with no freezing risk but plenty of December dampness.
