A warm, moisture-rich storm delivers widespread new snow to Utah mountains from Saturday night through Monday, with snow levels starting high near 7,500 feet before dropping to around 6,000 feet Sunday night and into the 5,000-6,000 foot range Monday. The Cottonwoods look best for totals and improving quality as colder air arrives, while the Wasatch Back and northern mountains also score meaningful snow with some denser periods early; winds will be a factor at times with gusty southwest flow.
A front-end burst Friday night into Saturday is followed by a warmer, wetter push late Saturday night through Monday that lifts snow levels across much of Idaho and western Wyoming, then a lighter Tuesday night-Wednesday refresh keeps flakes flying. Expect the best overall quality in Alberta and the higher Canadian interior (SLRs largely 14-20:1), while many U.S. resorts see SLRs slide into the 6-12:1 range during the warmest part of the cycle,
