The Sierra is getting slammed with yet another storm through Wednesday evening where 12-17 inches are likely, less wind, and low snow levels! Last weeks storm raised several issues with strong winds, extreme AVY control work, and delayed openings (5 feet in 3 days). Mammoth will also see significant snow from this storm. EPIC alert hoisted due to low snow levels and no expected wind issues this week!
ROCKIES: Light to moderate snow will be nearly continuous over the Southern Idaho, Northern Wasatch (Utah), and eventually most of Colorado over the next several days. Peak snowfall is expected Wednesday PM in the Wasatch continuing through Friday AM. Expect 2-4 tonight, 3-7 Wednesday, and another 6-12 by late Thursday night. Resorts such as Powder Mountain might see higher amounts. Colorado will see snow in the 4 corners under SW flow late Wednesday and Thursday AM (4-9). Winds will eventually switch to the NW bringing a good chance of snow to the I-70 corridor through Friday (6-10). This system is not overly convective however appreciable amount are likely due to the long duration event of moderate snowfall. The Tetons stay on the northern cusp of heavy precip however will see light to occasional moderate snowfall.
NORTHWEST: The Eastern Cascades are in a wet pattern for the next 24 hours with 9-12 inches likely over several areas. The West slope of the cascades will see light to moderate snow (4-8) over the next 24 hours (Crystal Mountain favored with southerly flow) and higher amounts in the southern areas towards Mount Hood in Oregon (9-14).
EAST COAST: Heavy snowfall will break out over New England Wednesday evening and continue at it’s peak on Thursday AM. Areas in Southern and Central NH,VT, and ME are favored as well as inland areas of NY, and MA. Expect 7-12 inches in many locations inland from the coast. Thursday will be a great storm ski day and free refills by the end of the day. I would consider, resorts near North Conway, Bethel Maine, and even Gunstock as targets for the heaviest snow.
Long Term: High pressure seems to take hold this weekend for many areas including the NW however we see more moisture headed into the Cascades in earnest just after New Years. Hopefully some of this will migrate into the Sierra and Rockies later in that week.
Wednesday: Lake Tahoe resorts (Expect 9-14), Northeast Oregon (Mount Hood), and NE Cascades (White Pass). Wasatch might get 4-9 by 2PM?
Thursday: Snowbird, Alta, Powder Mountain, Snowbasin, Canyons, Brighton, Solitude (5-10 new from overnight). PM- Vail, Beaver Creek
Friday: Light snow on top of 5-10 inches along I-70 in Colorado especially West of Summit County
