Overview
- Portland stays sunny and dry through early next week with highs around 53–54°F under a persistent ridge of high pressure.
- East winds channeled through the Columbia River Gorge are producing gusts from 35–65 mph in typical hotspots, with the strongest winds Friday into Saturday before easing Sunday.
- Central Oregon remains warmer than normal with highs mostly in the 40s to 50s and the potential to reach near 60°F on Tuesday, though a trapped fog layer kept some lower elevations cooler Friday.
- An Air Stagnation Advisory continues, with an early Friday Air Quality Alert and recent overnight readings reaching unhealthy levels under stagnant surface conditions.
- Nights remain cold with lows in the teens and 20s, and a slight chance of rain or snow returns late Wednesday or Thursday as the ridge weakens.
