Oregon wakes to a quiet, heavy stillness this morning as cold air settles into the Willamette Valley. Breath fogs the air, rooftops feel damp, and the sky holds low, muted color that barely moves.
According to the National Weather Service in Portland, an Air Stagnation Advisory remains in effect for Eugene and surrounding areas through Sunday morning. Light winds and stable conditions are trapping pollutants near the ground, allowing air quality to gradually decline.
Temperatures early today hover near the mid-30s, with calm winds offering little relief. Afternoons warm modestly into the low 50s, but the lack of mixing keeps the air feeling heavy. Smoke from wood stoves and vehicle emissions may linger longer than usual, especially during morning and evening hours.
Residents with respiratory conditions should limit prolonged outdoor activity. Officials recommend reducing wood-burning when possible and avoiding unnecessary idling. To be fair, conditions feel calm, but stagnant air can quietly create health concerns.
Looking ahead, Saturday and Sunday remain mostly cloudy with cool mornings and mild afternoons. A slight chance of rain arrives late Sunday night, signaling a possible shift in the weather pattern. That change could help break up stagnant air as the new week begins.
Drivers should expect localized fog during colder mornings, particularly near rivers and low-lying roads. Visibility may drop quickly before sunrise, so slow down and allow extra travel time. While no snow or ice is expected, damp roads and cold air can still catch commuters off guard.
By early next week, highs climb into the mid-50s, with better air movement expected. For now, winter’s quiet grip holds firm.
