Oregon – A clear, cold start gives way quickly this morning as clouds thicken over the Willamette Valley and rain begins to spread back into Portland. Pavement that dried out overnight will soon turn slick again, setting the tone for a wet New Year’s Day and an unsettled first weekend of 2026.
According to the National Weather Service in Portland, rain becomes widespread today with temperatures topping out in the mid-40s. Light winds keep the air chilly, and steady rainfall is expected to persist into tonight. While rainfall totals remain modest, the timing may slow holiday errands and New Year’s travel across the metro area.
Drivers along I-5, I-84, and Highway 26 should prepare for reduced visibility and slick lanes, especially during heavier bursts of rain. Bridges and overpasses may feel extra cold early, though freezing conditions are not expected in the city. Plan extra time and increase following distance during peak travel hours.
Rain continues into Friday, then transitions into on-and-off showers through the weekend. Highs rebound into the mid-50s, but nights stay cool, keeping roads damp well into the morning. With multiple wet days ahead, drainage issues and ponding water may develop in low-lying spots.
While snow is not expected in Portland, winter travel impacts will continue in the Cascades. Locally, umbrellas and rain jackets remain essential, and outdoor plans may need flexibility as showers linger.
Additional updates are possible as storms line up offshore. Heading out today or traveling this weekend? Tell us how road conditions look in your part of the metro.
