Oregon – Rain drums steadily on rooftops across Portland this morning, coating streets in a glossy sheen as south winds ripple through the trees. The damp chill sets the tone for a day defined by umbrellas and slick commutes — the kind of gray stretch that signals winter is closing in on the Pacific Northwest.
According to the National Weather Service, steady rain continues through midday before tapering to lighter showers Friday. Wind gusts may reach 30 mph, particularly in exposed areas and along I-5, where drivers could face spray and standing water. Rainfall totals are modest — generally less than half an inch — but visibility may drop quickly during heavier bursts.
Friday will stay mostly cloudy, with highs near 55°F. A few scattered showers linger into Saturday morning before drier, calmer air filters in from the north. Sunday looks partly sunny and cool — a welcome break before early December brings another shift toward colder air and possible lowland frost.
NOAA’s 6–10 day outlook highlights a broad cold trough setting up across the central and eastern U.S. starting December 2. That same pattern could nudge cooler, wetter air back into Oregon, keeping the first week of December seasonably chilly and unsettled.
