Portland, Ore. – A gray dawn blankets the Willamette Valley as light rain dots windshields and glistens on wet pavement. The early-morning mist carries that unmistakable October chill — and while more showers are due through Wednesday, the region will soon catch a brief break in the rain just in time for Halloween.
According to the National Weather Service in Portland, scattered showers will move through the metro area today, with steadier rain likely this evening. Roads along I-5 and I-84 could be slick during the morning and evening commutes, especially near Gresham and Vancouver. By Wednesday, conditions improve as high pressure edges in from the Pacific, pushing clouds eastward and allowing some late-day sun to peek through.
Thursday brings the calm between systems — partly sunny skies, light northeast winds, and highs near 60°F. Trick-or-treaters across Multnomah and Clark Counties can expect dry sidewalks and mild air Friday evening, though temperatures will dip quickly into the low 50s after sunset. Parents should plan for light jackets and keep an eye out for fog patches forming near the river valleys.
Looking to the weekend, another system is expected to move in late Friday night into Saturday, bringing steadier rain and gusty south winds along the coast range. Early next week hints at a broader pattern change — cooler air settling across the Pacific Northwest as November begins. After all, this is the season when fall’s gray rhythm slowly gives way to winter’s edge.
