Oregon – Rain streaks across windshields in Eugene this morning, with wet pavement already slowing traffic along I-5 and Highway 126 as showers expand across the southern Willamette Valley.
According to the National Weather Service in Portland, rain increases through the day with a 90% chance of precipitation by afternoon. Highs reach near 62°F, while south winds gust up to 20 mph. Roads will remain slick, especially during heavier bursts.
Across Lane County, showers continue into Wednesday with highs near 55°F. Rain becomes more persistent by midday, keeping surfaces damp and visibility reduced for much of the day. Plan extra time for travel and keep headlights on.
A sharper shift arrives late Wednesday. Colder air pushes in, dropping temperatures to near 32°F by early Thursday, March 26. Widespread frost develops by early morning, and any leftover moisture could freeze on bridges and overpasses. This raises the risk of slick spots during the early commute.
By Thursday afternoon, skies turn sunny with highs near 56°F, offering a brief dry break. Friday warms further to near 64°F under clear skies, though another round of chilly mornings with frost remains possible.
Drivers should stay alert during early morning hours later this week. Wet roads followed by freezing temperatures can create dangerous black ice, especially on untreated surfaces. Protect sensitive plants as well, as frost could impact early spring growth.
