EUGENE, Ore. – Morning headlights glint off rain-slicked pavement across the southern Willamette Valley as steady rain and gusty winds push through western Oregon. The storm brings another round of classic November weather, with soggy commutes and localized ponding expected before a clearer, calmer weekend.

The National Weather Service in Portland reports a 100% chance of rain today, with the heaviest showers expected through midmorning before tapering later this afternoon. Winds from the south will gust up to 25 mph, adding an extra chill to the 61°F high. Rainfall amounts may total up to a quarter inch, with slightly higher totals in the Cascade foothills.

Travelers along I-5 from Eugene to Salem should plan for wet driving conditions and reduced visibility, especially through midday. Wet leaves and pooling water could make side roads slippery. By Friday, the system weakens, leaving only a few scattered showers before sunshine starts to break through by afternoon.

Saturday and Sunday promise a much-needed break — partly sunny skies and highs near 61°F — perfect for outdoor plans or early holiday errands. Morning fog may linger briefly in valley areas before lifting into crisp, cool sunshine.

Forecasters hint at another system early next week, possibly bringing light rain and cooler air just before Veterans Day. For now, the Willamette Valley enjoys a brief pause between storms — a reminder that Oregon’s early winter rhythm has officially begun.
