This will be primarily an all-snow event, with medium-density snow and ratios near 12:1. Little Cottonwood Canyon is favored with 18”. At the same time, Brighton and Solitude should each pick up around a foot. Snowbasin may start as rain before quickly changing to snow, with totals near 10 inches for the Sunday–Monday period. Park City and Deer Valley could also begin warm with some mixing or rain, but should finish with a solid 8–10 inches. A smaller but colder follow-up system from Tuesday into Wednesday could add another 4–8 inches at AltaBird, pushing storm totals close to 2 feet by Wednesday.
Below: U of U predicting 16” by noon on Monday for the Alta (Collins) plume.

_________________
The Pacific Northwest is finally set to receive a substantial cold front beginning Tuesday evening, bringing snow-to-liquid ratios up to 15:1 in Washington (light to medium density) and around 12:1 in Oregon (medium density). The system will deliver up to 4 inches of Liquid, meaning locations such as Mt. Baker Ski Area could see totals approaching 4 feet by Thursday night. Snow levels will remain below base areas throughout the event, with the heaviest snowfall from Tuesday night through Thursday evening.
Below: 4” of Liquid set to drop on both Oregon and Washington by the end of the day Thursday, translating to 30-40” of snow.

The following 3 days will see heavy, consistent snowfall, with snow ratios ranging from 11:1 to 16:1. The cold front will move in Tuesday night, dropping that SLR and creating some blower pow on Wednesday.
