Oregon – Sun breaks through this morning, but clouds are already lining up offshore, signaling a sharp shift to a wetter spring pattern.
Portland climbs into the mid-70s early, offering a brief taste of warm, dry air. That warmth fades quickly as moisture pushes inland by late day and into Friday.
According to the National Weather Service, rain chances begin increasing Friday after late morning, starting near 20% before ramping up into the evening. Roads may stay mostly dry early, but conditions change fast after sunset.
By Friday night, rain becomes likely with an 80% chance across the Portland metro, including Vancouver and the I-5 corridor. Expect wet pavement, reduced visibility, and slower evening travel. Plan extra time.
Saturday brings widespread rain, especially through midday and afternoon hours. Rainfall becomes steady at times, with another 80% chance and periods of moderate showers. Keep umbrellas ready and avoid sudden braking on slick roads.
Rain lingers into Sunday, though slightly lighter. Highs drop into the mid-50s, replacing the earlier warmth with a cooler, damp feel across northwest Oregon.
Drivers should stay alert during peak travel windows. Wet roads and reflective glare can reduce visibility quickly. Use headlights and increase following distance.
Looking ahead, early next week stays unsettled with additional chances for showers before gradual clearing midweek. A warmer pattern may return late next week, hinting at more spring-like conditions.
