West is best over the next five days for new snow. I'm forecasting three different storm systems. In the Northeast, some snow early and then it warms up with rain/snow late in the period.
California: The jet stream remains active. Three different storm systems are lined up. The best snow falls above 7,000 feet with all three storm systems. Each storm drops about a foot of snow accumulation at Tahoe and Mammoth—grand totals of 2-3 feet. Could there be a 4-foot total? Yes. The first storm occurs on Wednesday-Thursday, the second storm occurs on Friday-Saturday and the third storm occurs on Sunday-Monday.
Colorado, Utah: Three different storm systems are lined up. The first storm occurs on Thursday-Friday, the second storm occurs on Saturday, and the third storm occurs on Sunday night through Monday, trickling into Tuesday. In Utah, the first two storms deliver moderate snowfall accumulations and the third looks heavier. In Colorado, each storm delivers about 3-6 inches of snow accumulation—possibly a bit more with the third. The heaviest accumulations are headed for the Southern Mountains, where 2 feet of total snow accumulation is likely. Wolf Creek, Purgatory, Telluride, Silverton, Crested Butte, Monarch and Snowmass are all in good position. Taos in New Mexico also looks good.
Wyoming, Montana, Idaho: I'm forecasting three different storm systems over the next five days, but the brunt of each storm drops just south of the region. Idaho is in the best position for the most snow overall. The first storm continues on Thursday and tapers off on Friday, the second storm occurs on Saturday and the third storm occurs on Sunday-Tuesday. The first storm delivers moderate to heavy snow to Idaho, but only light snow accumulations to Montana and Wyoming. The second storm is light all the way around. The third storm appears primarily light, but with a few pockets of moderate snow in southern Idaho and Wyoming. Sun Valley, Schweitzer, Whitefish and Jackson Hole are in the best position through the weekend. Overall, Thursday and Friday are the two best days to ski powder at Sun Valley and Schweitzer.
Pacific Northwest: Three different storm systems are lined up. The first storm is the strongest delivering heavy snow accumulations to the high Cascades and volcanoes. The second and third storms deliver light to moderate snow accumulations.
Whistler/Blackcomb: There are three different storm systems lined up, but it's really the first storm that delivers the heaviest snow. That storm continues on Thursday and ends on Friday. The second and third storm systems deliver light to moderate snow accumulations through the weekend. So, the best time for skiing big powder is Thursday-Friday.
Northeast: The best days to ski powder are Thursday and Friday. After that the temperatures warm up and a storm on Sunday night to Monday starts as rain then turns to some snow high up. Hit Mount Snow, Killington, Okemo, Cranmore, Wildcat, Ragged Mountain or Sunday River on Thursday-Friday.
