Wider weather episode

A sharp trough resulted in a potent winter storm impacting Utah, largely in two separate waves with a break between them. The first wave was within the prefrontal and milder southwesterly, which brought more of the high elevation snowfall. A reinforcing secondary wave moved through after the front within a cooler northwesterly flow, dropping snow levels and resulting in valley impacts, though at levels below warning/event amounts.
