EUGENE, Ore. – The Willamette Valley wakes under a low gray ceiling this morning, mist beading on windshields and dampening sidewalks. A break in the clouds looms, but it’s temporary—the next in a line of Pacific systems is already forming offshore.
According to the National Weather Service in Portland, light drizzle early today will give way to gradual clearing by midday, allowing highs to reach the low 60s. Sunshine returns briefly Thursday, but clouds increase again by nightfall. Calm winds and mild air will keep conditions pleasant through most of Thursday afternoon before the atmosphere reloads for the next wet push.
By Halloween Friday, skies turn mostly cloudy and breezes pick up slightly from the southwest. Showers are expected by late afternoon or early evening, arriving just as families begin trick-or-treating. Rain chances rise to 40% after sunset, and slick roads could slow traffic along I-5 between Eugene and Albany. Residents should plan for umbrellas and reflective gear, as visibility could drop in the drizzle.
Saturday brings steadier rain across the southern valley, lasting through early Sunday. Temperatures stay seasonable, with highs near 60°F and lows in the mid-40s—cool, damp, and unmistakably Pacific Northwest.
To be fair, it’s classic late October weather—an early taste of the long wet stretch ahead.
After all, clocks “fall back” at 2 a.m. Sunday, just in time for darker mornings, earlier sunsets, and that familiar rhythm of Northwest rain to mark November’s arrival.
