Moderate snow is currently falling over the Tahoe basin especially above 6500 feet. Snow levels are fluctuating greatly due to trapped cold air in the valleys. The bulk of moisture will fall from Mammoth (Heaviest) stretching north to Interstate 80 tonight (8-14 inches north and 10-15 south). Wednesday will be a powder day at upper elevations. A stronger system is due on Wednesday afternoon into Thursdaywhich favors northern California (Tahoe will see an additional 14-18 inches). Colder air is possible with this system but levels still above 7,000.
Rockies/Cascades: Today brought some amazing conditions to the Tetons where a foot of moderate dense snow brought “Hero” like conditions (Let it rip) to Jackson Hole Mountain Resortwhere I knocked off early morning laps on Thunder including the lower Sublette Ridge (Dense below Sublette). Solid 10 out of 10 on the fun factor with amazing coverage! The week ahead will bring light snow showers to the Tetons Wednesday, increasing Thursday mid morning through the evening (1-3 Wed, 4-6 Thursday, 1-3 Friday). The Wasatch sits between systems to the south on Wednesday/Thursday as well as snow falling over Idaho and Wyoming. Light snow is likely Wednesday in the southern and northern Wasatch (2-4). Areas favored by SW flow such as Big Cottonwood, and Snowbasin might see higher amounts?
Colorado will reap high elevations rewards (Leftovers) in the San Juans Wednesday-Saturday (Light amounts with the exception of moderate on Thursday PM). Some upper elevations around Wolf Creek, Silverton could see a sum total of 5-10 inches spread out over the period (No single deep event).
The Cascades do not impress (6-7,000 foot snow levels) until this weekend when a decent storm could brings colder temperatures and a good snowfall (Late Saturday-Sunday). Stay tuned! Next week in the NW looks very wet with another Atmospheric River event setting up (Cold air trapped up north). Significant low elevation rain and high elevation snow a good bet.
