Oregon – Cold air hangs low across the Willamette Valley this morning, frosting rooftops and stiffening lawns before sunrise. Breath turns visible, windshields glaze over, and untreated roads feel slick in spots.
A widespread frost grips Eugene early today, with temperatures near 28 degrees at daybreak. Calm winds and lingering moisture created ideal freezing conditions, raising concerns for black ice on bridges, shaded roads, and neighborhood streets.
Drivers heading out early should slow down and allow extra braking distance. Side roads, bike paths, and sidewalks may feel deceptively slick through mid-morning. Frost-sensitive plants are also at risk, especially in low-lying areas.
Temperatures recover into the upper 40s later today, but the cold pattern does not fully release its grip. Another frosty start is expected overnight, with lows hovering near the freezing mark again. Patchy fog may also develop, reducing visibility during early travel hours.
By Wednesday, clouds increase as a Pacific system approaches. Rain chances rise late in the day, ending the frost threat but introducing new travel concerns. Wet pavement arrives ahead of New Year’s Day 2026, and rain becomes more widespread by Thursday morning.
New Year’s Day looks gray and damp in Eugene, with steady rain likely at times and highs near the upper 40s. While snow is not expected in town, the transition from freezing mornings to rain could still cause slick conditions early, especially where frost lingers before temperatures climb.
Showers continue into Friday, with highs pushing into the low 50s. The first weekend of 2026 stays unsettled, favoring periods of rain rather than winter precipitation at valley level.
Plan extra time this morning, scrape frost fully, and watch for icy patches. Traveling for New Year’s or heading out early today? How cold did it feel where you are?
