Oregon wakes to damp streets and muted light this morning as drizzle clings to sidewalks and the air feels unusually heavy. Sound carries farther than normal, and the city seems wrapped in stillness.
According to the National Weather Service in Portland, an Air Stagnation Advisory remains in effect through Sunday morning. Light winds and a strong inversion are limiting air movement, allowing pollutants to build near the surface across the Portland metro and much of the Willamette Valley.
Temperatures start the day in the mid-40s, with highs reaching the low 50s this afternoon. Cloud cover sticks around, and occasional light drizzle keeps pavement wet. While rain amounts stay minimal, the lack of mixing prevents the air from clearing out.
Residents with asthma or other respiratory conditions should take precautions. Officials recommend limiting outdoor exertion and avoiding wood burning when possible. To be fair, conditions may not look dramatic, but stagnant winter air can quietly degrade air quality over time.
Drivers should also stay alert. Damp roads combined with cooler temperatures can create slick spots, especially during early morning and late evening hours. Reduced visibility may develop at times, particularly in low-lying areas and along river corridors. Allow extra time if traveling after dark.
Looking ahead, Saturday remains gray and calm, with little change in air quality. By Sunday, light rain chances increase, which may help slightly, but meteorologists expect limited improvement until a stronger system arrives next week.
Nationwide, winter weather remains active, with snow and severe storms impacting other regions. Locally, Portland’s main concern stays the slow buildup of pollution under quiet skies.
Keep windows closed if sensitive to air quality. Plan lighter outdoor activity. How does the air feel in your neighborhood this morning?
