THE WEST STAYS WET WITH TEASES IN THE SIERRA, WASATCH , AND EVENTUALLY COLORADO THIS WEEK.
Summary – April 16, 2017 8AM MST END OF SEASON FUND DRIVE FOR POW!
Happy Easter Sunday everyone! I’m in the mountain bike mode posting from Boulder with my thoughts looking at the Wasatch for Wednesday morning if your desperate (6-8 inches) or perhaps the Sierra as 3 systems produce several periods of 3-6 inches adding up to nearly a foot at higher elevations by late Tuesday(Southern areas favored). Colorado gets a light tease midweek with the Front Range near Denver perhaps seeing higher amounts late week (Upper peaks). The long term charts show a possible deeper system late in the month with perhaps good NW flow for the northern Rockies. Please consider a donation if either grabbed powder from our forecasts or lived vicariously through it! I really hope to be able to rebuild this site for next season!
Short Term Forecast
Light snow will be falling in the northern Sierra this evening that tapers by 3 AM (3-6 likely above 8,000 feet). There is a break in the action early Monday morning. The next wave of action enters the Sierra e Monday mid- morning with another 2-4 inches for last chairs. “It might be worth it if your already there but not for a long term chase.” Expect low crowds and snow that falls Sunday night combined with late Monday could allow you to find deeper pockets late in the day. Very little new snow will be found at the bases. Models push moisture into the southern sides of Lake Tahoe so areas like Kirkwood might be a better bet (further south and higher elevation). Snow continues perhaps moderate at times above 7500 feet into Tuesday. Models show a shift slightly south of of the lake so areas up north will see less snow. Mammoth is a wildcard with moisture focused just north but i’ts only a guess at this point. The highest snowfall will be south of Lake Tahoe and north of Mammoth (Could cause some wide variations on snow totals).

The Cascades repeat! Sun and warming temperatures today migrate to an unsettled pattern beginning early next week. Continued rain below 5,000 feet and light to moderate snow at the upper peaks of the ski areas will bring light snow through most of the upcoming week (Late Monday-Friday).
The Wasatch grabs leftovers Tuesday PM/Wednesday AM with 5-7 inches above 7500 feet likely. I would aim for 1st chairs in the Cottonwoods (most resorts will be closed except for Brighton and Snowbird). It’s worth a short term chase- but not from a distance.
The Tetons nab light snow above 7,000 feet Monday with a break Tuesday morning (1-3 inches). An uptick of moisture might bring a freshening to Grand Targhee Tuesday night (CLOSED FOR THE SEASON). Teton Pass might be an option.
Colorado earns another taste of winter as a swath of light or moderate snow and colder temperatures brings 3-6 inches or more to areas along or north of I-70 (Northern areas favored). Highlights will be Wednesday during the day into the evening hours.

Models show an uptick of moisture for the Front Range of Colorado late this week. Snow may increase with up slope flow with resorts closest to Denver by Friday/Saturday at the highest elevations.
The long range ensembles show an increasing chance of continued moisture in the Pacific Northwest in week #2. There is a chance that a significant low drops down into the Cascades, Panhandle of Idaho, and northern Rockies towards the end of the month. It’s 10 days out so models are likely to change. My suspicion is that the end of April may find some deep winter surprises in the northern Rockies.
