A Pacific trough brought up to 60 kt cross barrier flow and lee side surface low for strong winds along the Rocky Mountain Front. Unlike most of the November wind events in 2020, strong wind gusts did not move onto the plains of Central/North-central MT.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS TFX wrote it up.
