A Misty Monday: Rain Gear Required for Portland's Chilly Start

Morning Mist and Light Rain

As Portland wakes up this Monday, February 9, 2026, residents will find a familiar dampness hanging over the Rose City. The day begins with light rain and a high humidity level of 91%, creating a misty atmosphere for the morning commute. Temperatures are starting at a cool 45°F, though a slight breeze makes the air feel more like 43°F. Early travelers should be prepared for wet pavement and the potential for reduced visibility during the peak morning hours.

Afternoon: A Break in the Showers

By midday, the steady morning rain is expected to taper off into scattered showers. The forecast indicates a transition toward partly cloudy skies as the chance of precipitation drops to approximately 30%. The mercury is expected to climb to a daytime high of 51°F. While this offers a brief reprieve from the morning's gloom, the lingering moisture and high humidity will maintain a crisp, biting chill. It is a perfect afternoon for layered clothing—a waterproof outer shell over a warm sweater will be the uniform of choice for those heading out for lunch or afternoon errands.

Evening and Overnight Outlook

As evening approaches, the clouds will settle back in, leading to a mostly cloudy night. The probability of rain remains low at 20%, but the air will remain saturated. Temperatures are projected to drop steadily after sunset, eventually reaching an overnight low of 37°F. While conditions are expected to stay above the freezing mark at sea level, the high humidity will ensure a damp, cold night that may feel significantly frostier than the thermometer suggests.

Travel Safety and Preparation

There are currently no active high-wind or flood warnings issued for the Portland metropolitan area today. However, motorists are advised to exercise caution on bridges and overpasses where the combination of morning rain and falling nighttime temperatures can occasionally create slick surfaces. While the afternoon may tease residents with a few dry spells, the overall forecast suggests that umbrellas and rain boots remain essential equipment for the duration of the day. Looking ahead, this pattern of cool temperatures and intermittent clouds is expected to persist into Tuesday.
