Oregon’s Willamette Valley is drenched this morning, with light rain and mist clinging to streets across Eugene. Headlights reflect off slick pavement along I-5 and Beltline Highway, and temperatures hover in the low 40s. If you’re commuting, slow down and leave extra space.
According to the National Weather Service in Portland, rain continues through early afternoon with highs near 53 degrees. Winds stay light, shifting west around 6 mph later today. Rain chances remain near 90 percent, with light additional totals expected.
Showers taper later tonight, but clouds linger. By Wednesday, scattered showers redevelop, mainly before late morning. Snow levels drop near 2,700 feet, meaning higher elevations in the Cascades could see fresh accumulation. Valley floors stay too warm for snow, yet chilly air settles in behind the system.
That colder air sets up a frost risk by early Thursday. Lows dip near 30 degrees with widespread frost possible before sunrise. Bridges and untreated rural roads could turn slick if moisture refreezes. This is prime time for flash freezing, especially where rainwater lingers.
Thursday afternoon rebounds to near 53 with partial sunshine. Friday turns mostly sunny with highs around 55, signaling a gradual warming trend. Weekend rain chances return, but temperatures trend milder into early next week.
The 6–10 day outlook favors above-normal temperatures developing across western Oregon, hinting at early Spring Warmth building beyond the weekend.
