What happened

The episode as NWS BOI wrote it up.

A strong Pacific system that had tapped into a plume of tropical moisture dumped heavy snow across Southeast Oregon, causing the closure of Interstate 84 between Baker City and Ontario from late on the morning of the 28th until 8 a.m. the next day. Six to ten inches of snow fell across the area but blowing and drifting of the snow made accurate measurement difficult. Numerous slide-offs and motor vehicle collisions occurred but no injuries were reported.
