Oregon starts the day under a cold, quiet sky, with breath visible and pavement still holding the night’s chill.
Oregon’s Weather Alert for Portland focuses on a calm but cold start, followed by a wet, impactful midweek shift. Early temperatures hover in the mid-30s, cold enough for frost on lawns and shaded sidewalks. While skies stay mostly cloudy, a brief sun break helps temperatures climb near 50 degrees later today. That warming feels mild, but surfaces remain cold enough for refreeze after sunset.
Dry conditions hold into Tuesday, keeping travel manageable for now. By Tuesday night, the pattern begins to change. Moist Pacific air pushes inland, increasing rain chances and cloud cover. Roads may stay damp, and reduced visibility becomes more noticeable during late evening drives.
Wednesday marks the most active stretch. Rain chances rise to around 40 percent during the day, then strengthen Wednesday night. Temperatures climb into the low-to-mid 50s, which limits snow risk in the city. However, colder pockets and elevated roads could still feel slick during late-night hours. Expect steady rain, reflective pavement, and slower commutes along I-5, I-84, and surface streets.
Thursday keeps the wet trend going. Rain remains likely through much of the day, with highs near the low 50s. While flooding is not indicated, repeated rainfall can clog drains and pool water at intersections. Drivers should plan extra time and keep headlights on during heavier showers.
Looking ahead, NOAA’s 6–10 day outlook shows near-normal temperatures and easing precipitation into early February. That suggests a calmer pattern after this midweek system passes.
For now, winter still sets the tone. Dress warmly this morning, watch for slick spots tonight, and prepare for wet travel midweek. How are conditions shaping up on your commute today?
