Oregon — A heavy gray ceiling presses low over the Willamette Valley, muting the early light and leaving the morning air damp and cool. Streetlights glint off wet pavement, and a calm south breeze pushes faint mist across porches and driveways. These subtle early cues mark the beginning of a wetter pattern that strengthens through Sunday and into Monday—right as early Thanksgiving travel begins to rise across I-5, I-205, and Highway 26.

Travelers heading toward Salem, Vancouver, or the Coast Range should prepare for slower conditions whenever steadier rain arrives. Wet roads often hide thin slick spots during the first few hours of rainfall, so drivers may want extra braking distance and reduced speeds, especially near busy merges and downtown interchanges. Those planning early holiday errands should keep umbrellas ready and allow some buffer time in case showers intensify.

For now, today brings a mix of mostly cloudy skies and mild temperatures. A few passing rain pockets may develop late morning, though winds stay relatively light. To be fair, this slow start disguises the stronger moisture waiting offshore. Models hint at an early Winter Tease pattern, with thicker clouds, longer rain bursts, and subtle cooling as the week approaches Thanksgiving.

Rain becomes more organized late Sunday morning. Patchy fog may form before sunrise, and drizzle could linger long enough to reduce visibility on higher corridors like Cornelius Pass and Sylvan Hill. By Sunday night, steadier rain is likely, and new precipitation may reach around a tenth to a quarter inch.

Monday continues the wet theme with showers likely before midday. Travel impacts remain possible during the morning commute, especially across the east side where fog and drizzle combine with heavier traffic.
