Oregon — Damp pavement and gray skies greet commuters across Portland this morning as low clouds hang over the Willamette River. The day begins quiet, but the weather pattern is already shifting. Increasing clouds and incoming Pacific moisture will bring multiple rounds of rain back to northwest Oregon through midweek.
According to the National Weather Service in Portland, the city will see a chance of light rain early today before skies gradually brighten this afternoon. Temperatures will climb into the upper 60s, offering a brief break between storm systems moving across the Pacific Northwest.
Conditions begin changing again Tuesday as moisture returns from the Pacific. Portland could see around a 50 percent chance of rain, with clouds thickening across the metro area and surrounding Willamette Valley communities.
Drivers traveling along Interstate 5, Interstate 84, and Interstate 205 should prepare for slick roads during heavier showers later in the week. Wet pavement and reduced visibility could slow travel during peak commute hours.
By Wednesday, rain chances continue across the region as another weak disturbance slides inland. High temperatures will remain mild, reaching the mid-60s, but skies will stay mostly cloudy through much of the day.
Communities including Beaverton, Hillsboro, Gresham, and Vancouver, Washington will experience similar conditions as the unsettled pattern spreads across the metro region.
Meteorologists say the broader weather pattern across the Pacific Northwest remains active this week. Moist Pacific systems will continue to move inland, bringing periodic showers across western Oregon.
Even with the rain, temperatures remain comfortably mild for mid-March. Nights will stay in the upper 40s to low 50s, preventing colder conditions from developing.
Residents planning outdoor activities should keep rain jackets nearby and allow extra travel time during periods of steady showers later this week.
