Multnomah County is predicting a Rainy weekend

Multnomah County, including Portland, is facing the possibility of a significant winter storm this weekend. The forecast suggests a potential for heavy snow, freezing rain, and temperatures well below average from Friday into the weekend. However, there is some uncertainty in the forecast, with computer models varying in their predictions. Some models indicate a major winter storm, while others suggest a drier and chillier weekend.

The National Weather Service has issued a Winter Storm Warning effective from January 11 at 12:12 AM PST until January 14 at 4:00 AM PST. The warning includes heavy snow with total accumulations of 2 to 4 feet, especially in areas above 3000 feet, and wind gusts up to 50 mph.

There are concerns about difficult travel conditions, white-out conditions due to gusty winds, and the possibility of power outages caused by falling tree branches. Cold wind chills as low as 25 degrees below zero could also pose a risk of frostbite on exposed skin within 30 minutes.

Residents and visitors are advised to be prepared for severe winter conditions and to keep updated with the latest weather forecasts and road conditions​

Expected Weather Conditions

  • Snow Accumulations: The region could see significant snowfall. Total snow accumulations are expected to range from 2 to 4 feet, with the highest amounts likely to be above 3000 feet.
  • Wind Speeds: Accompanying the snow, the region could experience wind gusts as high as 50 mph, contributing to reduced visibility and potentially dangerous travel conditions.
  • Freezing Rain: In addition to snow, there is also a possibility of freezing rain, especially in areas where temperatures hover around the freezing mark. This could lead to icy surfaces and further complicate travel.
  • Temperature Fluctuations: The temperatures are expected to be well below the seasonal average. The forecast suggests a wide range of possible high temperatures in Portland on Saturday, with some models predicting as low as 19 degrees and others as high as 42 degrees.

Checking road conditions through reliable sources like (for Oregon) and (for Washington) is recommended before embarking on any journey.
  • Power Outages: The combination of heavy snow, ice accumulation, and strong winds could lead to power outages. Residents should be prepared for potential disruptions and have alternative plans in place.
  • Personal Safety: With the possibility of extremely cold wind chills, it’s essential to dress warmly, in layers, and minimize exposure to the elements to prevent frostbite and hypothermia.
