Oregon – A thick chill settles over the southern Willamette Valley this morning, with mist clinging to fields and rooftops as Eugene wakes under a pale gray sky. The air feels crisp but damp — classic late November weather that hints at a pattern shift ahead of the Thanksgiving rush. Drivers should watch for patchy frost early, especially on bridges and shaded roads between Eugene, Springfield, and Creswell.
According to the National Weather Service, light rain develops by Tuesday afternoon, followed by steadier showers through Wednesday. Winds stay calm, but roads may become slick as moisture increases and temperatures hover near the mid-40s. The wet pattern will build through Thanksgiving, creating travel delays along I-5 and smaller highways through Lane County as an 80% chance of rain moves inland.
By Thanksgiving Day, Eugene can expect highs near 56°F with steady rain through much of the morning. Those heading toward Portland or the Oregon Coast should pack rain gear and plan for extra drive time. To be fair, this isn’t a major winter storm — but it’s the kind of persistent Pacific rain that makes travel slow, and it may mark the region’s first “winter tease” of the season.
Looking past the holiday, Friday and Saturday bring cooler air and a chance of lingering showers, while Sunday models hint at rain mixed with early snow in the Cascades — a possible sign that true winter weather isn’t far behind.
