Oregon starts this Saturday with dense fog hugging the Willamette Valley as scattered droplets cling to windshields and street signs across Portland. The air feels cool, still, and heavy—classic November dampness as holiday traffic picks up across the metro. Early Thanksgiving travelers should prepare for changing road conditions today and a wetter pattern pushing in by Thursday and Friday.
According to the National Weather Service, Portland trends partly sunny early but turns unsettled late tonight as a strong Pacific plume brings widespread rain. Visibility may fluctuate through the morning as fog lifts slowly from I-5, I-84, and bridges across the Willamette. Anyone heading out for early holiday trips should add a buffer for reduced visibility and potentially slick pavement.
Rain strengthens Thursday, becoming likely through midday as another steady band moves inland. Models hint at a “Winter Tease” in the higher terrain east of the city, where cold pockets could support a brief rain-snow mix in the Cascades. No low-elevation accumulation is expected, but mountain corridors—including Government Camp—may see slush or decreasing traction. To be fair, it’s not a major storm, but timing matters with Thanksgiving only days away.
Friday brings a slight chance of rain, though the overall system weakens. Clouds linger, and the ground stays damp across Multnomah and Clackamas counties. Travelers leaving Friday morning should see manageable road conditions in the city, though any lingering drizzle could slow traffic during peak departure times.
The weekend stays active. Saturday brings another chance of rain, followed by a similar pattern Sunday as moisture funnels inland. It’s a steady, familiar November stretch—wet air, crisp breezes, and early signs of winter building beyond the Cascades.
