Oregon – Frost glints on windshields, breath hangs in the air, and patches of fog blur familiar streets across the southern Willamette Valley. Eugene starts New Year’s Eve under a winter chill, with temperatures well below freezing before a wetter pattern takes over to begin 2026.
According to the National Weather Service, early-morning temperatures have dipped into the upper 20s around Eugene, with mist and patchy fog reducing visibility in spots. Areas of frost are expected through the morning hours, creating slick conditions on bridges, ramps, and untreated neighborhood roads.
In and around Eugene, drivers along I-5, Beltline Road, and Highway 126 should watch for sudden visibility changes and icy patches early. Fog gradually thins later in the morning, allowing clouds to break at times. Even so, cold pavement lingers into midday before temperatures climb toward the upper 40s.
Rain chances increase heading into New Year’s Day, marking a transition away from freezing concerns. Showers become more widespread Thursday and persist into Friday, keeping roads wet during peak travel times. While snow is not expected in the valley, nearby higher elevations could see wintry precipitation, affecting passes and regional travel.
By Friday and into the first weekend of 2026, steady rain dominates western Oregon. Gusty showers may reduce visibility at times, especially after sunset. Plan extra time if traveling, keep headlights on in rain and fog, and watch for water pooling on low-lying roads.
Additional advisories could be issued if freezing fog redevelops early or rainfall intensifies later this week. How cold did it feel where you started your morning?
