Wider weather episode

A preceding cold arctic air mass combined with a moist Pacific storm resulted in widespread heavy snow for Northwest Oregon including the coast and the Willamette Valley. Warmer air quickly moved in from the south mid-morning and the snow changed to freezing rain. East winds through the Columbia River Gorge maintained colder air to the north where the precipitation fell mainly as snow.
