The episode as NWS MFR wrote it up.
An incoming front brought Heavy Snow to areas of Eastern Oregon. No warning was in effect, but a Snow Advisory was issued for Oregon zones ORZ029/030 at 17/0434, effective from 17/2200 until 18/1600 PST. It was cancelled at 17/2042 PST, so this was largely a missed event.
