Wider weather episode

A cold season type of trough and associated surface features moved through Utah in early May. Ahead of the system, strong synoptic wind gusts occurred throughout portions of the state. While wind gusts decreased following a cold frontal passage, precipitation increased. Periods of post-frontal precipitation then continued in the unsettled northwesterly flow as the trough shifted through the region. Given anomalously cold air associated with the trough, some area mountains received Winter Storm levels of snow, and sub-warning snow amounts were even observed in some lower elevation valley locations. Following the systems departure, a fatal avalanche occurred involving multiple backcountry skiers.
