PORTLAND, Ore. — Low clouds hang heavy over the city, with a damp chill and mist clinging to bridges and car hoods across the Portland metro this morning. Fog and drizzle mark the calm before a wetter, more persistent pattern sets up later this week across northwestern Oregon and southwest Washington.
The National Weather Service in Portland reports intermittent showers through Wednesday, followed by a stronger push of rain Thursday night into Friday, with rain chances peaking near 70%. Early commuters should expect patchy fog developing late tonight and again before sunrise Wednesday, reducing visibility along I-5, Highway 26, and the Columbia River crossings.
Temperatures will stay mild—highs near 49–55°F, lows near 40°F—but steady rain later this week may make roadways slick, particularly during evening commutes. Forecasters note no major flooding threats, but warn that urban ponding and fog-related slowdowns could affect Friday morning travel.
By Thursday, rain will spread inland from the coast, with a steady drizzle turning to light rain by evening. The pattern continues through the weekend, keeping skies gray and streets damp well into next week. Residents planning early holiday errands or tree-lighting events should keep umbrellas handy and plan for delays.
Five-Day Local Outlook:
- Today: Cloudy, showers possible, high 49°F.
- Wednesday: Mostly cloudy, fog late, high 47°F.
- Thursday: Rain likely, high 48°F.
- Friday: Steady rain, high 55°F.
- Saturday: Rain continues, high 55°F.
