Portland, Ore. – Gray skies stretch over the Willamette River this early Monday morning, a quiet calm before the season’s next Pacific change. Portland’s brief window of fall sunshine is set to close as midweek brings clouds, showers, and the first steady run of cool, wet weather in days.
According to the National Weather Service in Portland, the start of the week will stay mostly sunny and mild, with highs near 60 Monday and climbing into the mid-60s by Tuesday. Winds remain light and conditions stable — ideal for commuters and outdoor projects. But this calm pattern won’t hold. By Wednesday afternoon, the next weather system will push inland, spreading light rain across the metro area, including Vancouver, Beaverton, and Gresham.
Showers are likely to expand Wednesday night into Thursday, with cooler highs in the upper 50s to mid-60s. Roads along I-5 and I-84 could turn slick during the Thursday morning drive. While snow levels stay high, hovering above 5,000 feet, early signs point to colder air late in the week — a potential early-season pattern shift that could lower snow levels next weekend.
Rain chances increase again Friday through Sunday, marking Portland’s return to classic October conditions — steady drizzle, damp leaves, and that familiar chill seeping back into the air.
For now, residents should take advantage of Monday’s and Tuesday’s dry stretch to clean gutters, prep gardens, and dig out those rain jackets. After all, Oregon’s true fall weather is finally on the move.
