The National Weather Service in Portland forecasts ongoing showers this afternoon and into Tuesday, with light snow expected over Cascade passes. These showers will taper off late Tuesday, giving way to a few dry days marked by chilly, frosty, and foggy nights and mornings. However, rainy weather is set to return on Friday, continuing through the weekend.
This afternoon, a frontal system moving through Northwest Oregon and Southwest Washington has brought significant precipitation and wind gusts of 45-55 mph along the coast and in wind-prone areas like the Columbia River Gorge and the high Cascades. While some heavier showers have resulted in non-accumulating snow above pass level, snow levels are expected to drop to around 3500-4000 feet this evening. Forecasts indicate a 45-80% chance of receiving up to 2 inches of snow at pass level overnight, with higher elevations in the Cascades possibly seeing 4-8 inches by tomorrow.
