Snow and Slush: Portland Braces for a Wintry Wednesday Mix

Morning: A Snowy Start for the Metro Area

Portland residents waking up this Wednesday, February 18, 2026, will find a classic Pacific Northwest wintry cocktail outside their windows. According to current National Weather Service data, the morning hours are expected to feature a mix of rain and snow showers. With snow levels hovering near 500 feet, neighborhoods at higher elevations—including the West Hills and Mount Scott—are likely to see light accumulations before the morning commute is over.

As the clock ticks toward 10:00 AM, the initial wintry mix will begin a slow transition toward straight rainfall. However, temperatures will remain quite chilly, starting near 33°F and struggling to rise. Travelers should be prepared for slushy conditions on side roads and bridges during the early hours.

Afternoon: The Midday Thaw

By early afternoon, the transition to rain will be complete for the majority of the Portland-Vancouver metro area. The high temperature for the day is expected to peak at approximately 43°F. While this slight warming will melt much of the morning slush, the atmosphere remains unstable, and showers are likely to persist throughout the day.

• Temperature High: 43°F (6°C)
• Wind: South winds between 5 to 10 miles per hour.
• Humidity: Remaining high at approximately 81% to 86%.

Despite the rise in temperatures, the air will retain a significant bite, and overcast skies will keep the city feeling damp and cold. Outdoor activities should be planned with waterproof gear in mind, as the chance of precipitation remains above 45% throughout the afternoon.

Evening: Accumulating Snow and Travel Impacts

As evening approaches, the weather takes a more serious turn. Forecasters have expressed moderate confidence in a narrow band of accumulating snow that could impact the Willamette Valley and the Portland metro area starting around 5:00 PM this evening. As the sun sets, the snow level is predicted to drop back down to 600 feet.

A mix of rain and snow showers will likely continue through midnight, with a low temperature of 32°F. The overnight period carries a significant risk of ice formation as moisture on the roads may freeze, leading to hazardous driving conditions for the Thursday morning commute.

Warnings and Safety Information

The National Weather Service has issued a Winter Weather Advisory for the region, effective from 5:00 PM Wednesday through Noon Thursday. There is moderate confidence that several inches of snow could accumulate in specific bands across the metro area. Travelers are urged to monitor local traffic reports and carry winter safety kits in their vehicles. Visibility may be reduced during periods of heavy snow showers, and public transit users should check for potential service delays as the wintry system moves through the valley.
