Umbrellas Required: A Soggy Sunday Sweep for the Rose City

A Damp Conclusion to the Weekend

Portland residents waking up this Sunday, February 8, 2026, will find a familiar gray curtain over the city. After a week of varying conditions, a dedicated moisture system has moved into the Willamette Valley, promising a day defined by persistent rainfall and high humidity. While the temperatures remain relatively mild for February, the dampness will be the defining feature of the day’s weather story.

Morning: Misty and Overcast

The morning hours start with heavy cloud cover and a high humidity level of approximately 95%. As of the early hours, the city is already seeing cloudy skies with mist beginning to transition into light showers. Temperatures are holding steady at a chilly 42°F. For those heading out to morning services or early brunch, the air will carry a heavy dampness, making the mid-40s feel significantly cooler. While there are no high-wind advisories currently in place, a light breeze is expected to accompany the arriving rain front as it pushes through the region.

Afternoon: The Rain Intensifies

The bulk of the day's precipitation is expected to arrive during the afternoon hours. Forecast models indicate a 75% chance of steady rain between noon and 5:00 PM. The mercury will climb to a daily high of 49°F, though it will likely feel like 48°F due to the saturation of the air. This period will see the heaviest accumulation, so motorists on I-5 and I-84 should prepare for slick surfaces and potential spray from other vehicles. It is a day better suited for visiting the Portland Art Museum or a local coffee shop than strolling through Washington Park.

Evening: Light Rain and Nighttime Outlook

As we head into the evening, the rain will transition from steady showers to a persistent light drizzle. Interestingly, the statistical chance of precipitation actually rises to 90% after sunset, ensuring that the ground remains wet through the night. The temperature will dip back toward a low of 42°F. The thick cloud base will prevent any overnight frost, keeping the valley floor safely above the freezing mark while maintaining the damp, cool atmosphere.
