Portland, OR – Oregon residents can expect one last stretch of golden autumn sunshine before a wet pattern settles in late this week. Forecasters say the state’s dry streak will hold through Wednesday, but by Thursday night, rain returns to the Portland metro area — just in time to cool things off for fall weekend plans.
According to the National Weather Service, temperatures will peak near 78°F Tuesday and hover in the mid-60s by Friday. Winds remain light through midweek, but a Pacific system moving inland Thursday could bring the first measurable rain since early October. Drivers on I-5 and I-84 should plan for slick roads and slower travel times by Friday morning.
Wednesday stays mostly sunny, with highs near 63°F and only a 20% chance of evening showers. Thursday’s forecast calls for a 30–50% chance of rain, increasing through the night. Friday looks damp, with highs around 64°F and steady rainfall likely into Saturday.
Weekend planners can expect a cool, cloudy stretch — perfect for indoor fall decorating or early Halloween prep. Temperatures dip into the upper 40s at night with steady showers through Sunday.
Looking ahead, Monday (Columbus Day) brings a break from the rain, with partly sunny skies and a pleasant high near 80°F — a brief return to warmth before Oregon settles into a true fall pattern.
