Wider weather episode

Unseasonably cold air was in place over the Pacific Northwest, with temperatures marginally cold enough for a low elevation snow event from the Portland metro northward. A storm system moved over northwest Oregon and southwest Washington bringing widespread snowfall to many areas north of Salem, Oregon. This system brought several inches of snow to the Willamette Valley in addition to the Coast Range and Cascades. By the late morning/early afternoon, much of the snow west of the Columbia River Gorge had transitioned to rain. This was not just your standard snowfall as it ended up being the first measurable lowland snowfall in the month of April.
