The wider storm

Two quick hitting shortwave troughs brought widespread and sustained precipitation to the western Oregon allowing for heavy snowfall across the Cascades. A third deep upper trough then quickly followed as well, and due to an accompanying warm-frontal boundary localized river flooding developed due to a combination of ample rainfall and snowmelt.
