Portland, OR – Raindrops shimmer on windshields as gray clouds drift across the Willamette Valley this morning, signaling another wet Pacific start for late November. Umbrellas open along downtown sidewalks, while headlights glisten through drizzle on I-5 and I-84. But this gray spell won’t last — clearer, colder air is just behind it.
According to the National Weather Service in Portland, light to moderate rain continues through midmorning Friday, with highs reaching the low-50s. Conditions will gradually dry this afternoon, leading to a mostly cloudy and cooler evening around 41°F. Winds ease as the system pushes east, setting up a calmer Saturday.
Saturday brings a 20% chance of light rain, mainly early, with skies brightening by afternoon and temperatures near 50°F. By Sunday, sunshine returns across northwest Oregon — but with a chill. Lows are expected to dip to the mid-30s, and patchy frost may develop in outlying areas and higher elevations.
Travelers heading home after the holiday should plan for wet roads Friday morning and frosty surfaces Sunday and Monday, especially before sunrise. While this isn’t a major storm, it marks the transition toward early December’s colder pattern. Models hint at another round of showers or even low-elevation snow east of the Cascades next week as temperatures trend below normal across the Northwest.
Keep coats, gloves, and umbrellas ready — winter’s first hints are settling in.
