Oregon – A steady curtain of rain sweeps across Portland this morning, coating sidewalks and leaving highways slick as commuters move through the metro area. Light mist hangs in the air, and headlights glow on wet pavement across the Willamette Valley.
Drivers across I-5, I-84, and Highway 26 are already dealing with damp roads and reduced visibility. Conditions remain unsettled through the day as a Pacific storm pattern pushes inland.
According to the National Weather Service in Portland, widespread rain continues through the day with up to a quarter inch possible. Afternoon temperatures climb near 50°F, while light south winds run between 6 and 8 mph.
Rain does not disappear quickly. Scattered showers redevelop late today and linger into Saturday afternoon. Temperatures rise slightly, reaching near 58°F, but cloud cover stays locked across northwest Oregon.
Another surge of moisture arrives Sunday morning. Meteorologists now track an 80% chance of rain by late morning, with gusty winds near 20 mph possible across the Portland metro and Columbia River corridor.
Residents should also prepare for the Daylight Saving Time shift early Sunday at 2 a.m., when clocks jump ahead one hour. The later sunset may help signal the gradual transition toward spring.
By Monday, showers intensify again across the region. Snow levels in the Cascades fall sharply from around 3900 feet to near 1800 feet, bringing fresh mountain snowfall while valley locations stay rainy.
Cool mornings and wet afternoons also raise the risk of flash freezing on bridges and shaded roads before sunrise, especially outside the urban core.
Looking ahead, long-range guidance suggests a gradual warming trend across the West later next week, hinting at the first consistent stretch of spring weather.
