From Morning Downpours to Midnight Mist: Today’s Portland Weather Report

Wet Morning Commute and Persistent Showers

Portlanders waking up this Thursday, January 29, 2026, will find the city under a thick blanket of gray as a wet weather system moves through the Pacific Northwest. Early morning reports indicate light rain is already falling across the metro area, with a 100% chance of precipitation through the first few hours of the day. Forecasters expect moderate rainfall totals to reach approximately 5mm by midday, making for a slick and slow morning commute. Visibility may be reduced during periods of heavier downpours, so drivers are encouraged to keep their headlights on and maintain extra following distance.

Afternoon Transition and Temperature Trends

As we head into the afternoon, the steady rain is predicted to transition into scattered showers. While the umbrella will remain a necessary accessory, there may be brief moments of reprieve between the clouds. Temperature ranges for today are as follows:

• Daily High: 51°F (11°C)
• Daily Low: 42°F (6°C)
• Current Temperature: 46°F, though high humidity makes it feel closer to 43°F.

Winds will remain relatively light but consistent, blowing from the south at approximately 11 km/h (7 mph) with occasional gusts reaching up to 17 km/h (10 mph). The humidity remains high at around 92%, contributing to a damp, heavy feel in the air that will persist throughout the day.

Evening Fog and Nighttime Outlook

By the early evening, the probability of rain will decrease slightly to around 25% to 40% as the primary system moves east. However, the excess surface moisture and cooling temperatures will likely lead to the development of fog patches. Mostly cloudy conditions will dominate the overnight hours, with the mercury dipping back down toward the low 40s. Visibility in the West Hills and near the rivers may become particularly hazardous after 8:00 PM due to the thick mist.

Regional Advisories and Mountain Travel

While there are no active wind or flood warnings for the Portland city limits, those planning to travel toward the Cascades should prepare for significantly different conditions. The National Weather Service and the Northwest Avalanche Center (NWAC) have noted that snow is likely for higher elevations, including the Mount Hood area. Avalanche danger is currently rated as Moderate for middle and upper elevations as new snowfall and wind build deeper drifts. Travelers are advised to check mountain pass conditions before heading out, as winter storm warnings remain in effect for the surrounding ranges.
