Chilly Clouds and a Hint of Frost: Portland’s Midweek Outlook

A Cold Start to Thursday
Portland residents are waking up to a brisk and overcast morning this Thursday, January 22, 2026. As the city settles into the heart of winter, the early morning hours are seeing temperatures hovering just near the freezing mark, with lows recorded around 29°F to 33°F. High humidity levels, reaching nearly 80%, are contributing to a damp, biting cold that may result in patchy frost on windshields and elevated surfaces. Commuters should prepare for thick cloud cover that will dominate the skyline throughout the morning commute.
Afternoon Conditions and Precipitation Chances
As we move into the afternoon, the mercury is expected to climb slowly, reaching a daytime high of approximately 41°F to 46°F. While the sun may remain hidden behind a stubborn layer of stratus clouds, there is a slight chance of precipitation. Meteorologists have noted a 25% chance of patchy rain or a light snow-rain mix during the peak of the day. However, significant accumulation is not expected within the city limits. Winds remain relatively calm, though a light breeze from the north might make the mid-40s feel closer to the high 30s. The air remains saturated with humidity hovering around 72%, keeping the atmosphere feeling heavy and cool.
Evening Forecast and Nighttime Cooling
By the evening, temperatures will begin their descent back toward the mid-30s. For those heading out for dinner or evening activities, expect damp roads and persistent overcast conditions. The chance of a stray shower remains low but present at roughly 20%. Overnight, the thermometer will dip back down to a low of 33°F. While the city is not currently under any major wind or rain warnings from the National Weather Service, the combination of near-freezing temperatures and lingering moisture could lead to localized slick spots on bridges and overpasses after midnight.
Regional Alerts and Mountain Travel
While the Portland metro area remains free of severe weather alerts today, mountain travelers should take note of conditions in the Cascades. Recent reports for Mt. Hood indicate firm and variable surfaces with colder temperatures at higher elevations. For those planning a trip out of the valley, ensure your vehicle is equipped for winter travel, as mountain passes may experience more significant icing than the temperate Willamette Valley. Locally, no flood or high-wind advisories are in effect, making this a standard, albeit gloomy, winter day for the Rose City.
