Oregon – Damp pavement glistens under streetlights as cold rain moves through the southern Willamette Valley early this morning. In Eugene, winter weather is active now, and small temperature changes could quickly impact travel and daily routines.
According to the National Weather Service in Portland, showers continue this morning with snow levels near 1,900 feet. Most areas stay rain, but brief rain-and-snow mixes remain possible before conditions ease later. Temperatures hold in the mid-30s early, keeping roads cold and increasing the risk of slick spots on bridges and shaded streets.
By late morning, showers taper and clouds begin to thin. Highs reach the mid-40s this afternoon, offering some drying. Even so, drivers along I-5 and Highway 99 should stay alert for wet roads and reduced visibility during lingering showers.
Tonight brings a sharper shift. Skies clear and temperatures fall quickly, dropping near freezing. Widespread frost develops by early Friday, especially in outlying neighborhoods and rural areas. This sets up a classic flash-freeze scenario where daytime moisture refreezes overnight. Plan extra time for the morning commute and watch for icy patches.
Friday turns calmer and brighter. Patchy frost fades by mid-morning, followed by partial sunshine and highs near 49. The quiet stretch continues into Saturday, though cold mornings remain a concern. Frost redevelops again early Saturday, then clouds return later in the day.
Sunday stays mostly cloudy with highs near the low 50s. Light rain chances return late Sunday night into early next week, but no major storms are expected for now. Meteorologists continue monitoring Pacific systems that could shift timing.
By late January, Eugene gains nearly 40 extra minutes of daylight, a small but welcome winter milestone. Seeing frost or slick roads near your home? Share what conditions look like where you are.
