A significant winter weather event is expected to hit western Washington, with lowland snow, sleet, and freezing rain predicted right before Valentine's Day. Meteorologist Shannon O'Donnell emphasizes the interplay between cold air and moisture, which is critical for snow formation in the region. Forecast models suggest that areas from Thurston County to the Oregon state line could accumulate between a trace and four inches of snow, especially in the Willapa Hills and the Capitol Forest. While southern regions are likely to receive the bulk of the precipitation, the Seattle area may also experience some snowfall by Friday morning. Additionally, areas in Oregon are expected to contend with dangerous freezing rain, emphasizing the storm's broader impact.

This weather pattern marks a change after a period of clear, cold skies, and residents should prepare for hazardous travel conditions. As temperatures rise over the weekend, the forecast indicates a transition to rain, which could further complicate conditions. The article serves as a timely reminder for residents to stay informed and make necessary preparations.
