EUGENE, Ore. – The quiet gray skies of early morning won’t last long. A steady stream of Pacific moisture is once again pressing inland, spreading wet pavement and glistening headlights across the Willamette Valley. The first drops will be light — but by Tuesday evening, another soaking rain event will be underway.
The National Weather Service in Portland expects periods of rain to increase through Tuesday, becoming heavy at times Tuesday night into Wednesday. Gusty southerly winds near 25 mph may accompany the front, especially in open areas and along Interstate 5 from Eugene north to Salem and Portland. Thunder is possible late Wednesday as colder air sweeps through.
Rainfall totals could reach one to two inches across western Oregon, with minor urban and small stream flooding possible where leaves clog drains. Commuters should expect slower travel, slick roads, and standing water during the Wednesday morning drive. For now, temperatures stay mild — upper 50s to low 60s for highs — but a cooling trend is expected late week.
By Thursday, showers will taper, giving way to partly cloudy skies and a brief dry break before another weak system approaches late Friday. Weekend conditions look seasonably cool and mostly dry, ideal for raking leaves or prepping for early holiday travel.
Still, this week’s pattern is a clear reminder that November weather in Oregon can shift fast — one day calm and cloudy, the next blustery and drenched. Keep rain gear close and watch for quick changes as early winter storms keep pressing across the Pacific Northwest.
