A nor'easter delivers heavy snow before New Year's Day to ski areas in the Northeast. Out West, a series of fast moving storm systems keep the snow falling.
Northeast: The window for heavy snow is Thursday to Friday in interior Connecticut, Massachusetts, New Hampshire, Vermont and Maine. I'm forecasting close to a foot of total accumulation at Mount Snow, Killington, Jay Peak, Sugarbush, Sunday River, Okemo, Jiminy Peak and Stowe. A pocket of 2 feet is possible in New Hampshire near Mount Washington, Attitash, Wildcat, and Cranmore. Interior New York State can expect moderate accumulations. A second smaller storm delivers light snow accumulations between Saturday afternoon and Sunday morning.
Colorado, Utah: There are two storms to watch. The first is a fast moving southern-track storm that hits southern Utah between Friday evening and Saturday, with light to moderate snow accumulations including Brian Head. That snow largely misses the Wasatch Front ski areas. That snow hits Colorado's mountains late Friday through Saturday with 3-8 inches of snow accumulation. The biggest snow amounts will fall in the southern mountains with less as you go north towards I-70. I would stick with Wolf Creek, Silverton Mountain, Telluride and Purgatory during this first storm. Taos in New Mexico is also a good bet. A second storm arrives on Sunday and continues on Monday and possibly Tuesday in both Utah and Colorado. Accumulations appear to be heavy with impressive two/three day totals.
California: There are two storms to watch (you may have light snow at Mammoth on Friday). The first storm is small and fast moving. It arrives on Saturday with light snow accumulations for Tahoe and Mammoth. The second storm is much larger and could last two full days. It arrives Sunday afternoon and continues on Monday and Tuesday. Heavy snow accumulations at Tahoe and Mammoth.
Pacific Northwest: There are two storms to watch. The first storm occurs on Thursday to Friday with moderate to heavy snow accumulations to the Cascades and high volcanoes. The second storm is right on its heels arriving mid-day Saturday continuing into Sunday morning. Moderate to heavy snow accumulations. The second storm hits both Washington and Oregon.
Whistler/Blackcomb: There are two storms to watch. The first storm on Thursday delivers moderate to heavy snow accumulations. The second storm on Saturday delivers light to moderate snow accumulations.
Montana, Idaho, Wyoming: There are two storms to watch. The first storm is smaller and fast moving. It arrives Friday and continues into Saturday morning with widespread 1-3 inch accumulations. The second storm is slightly larger and arrives first in Idaho and Montana on Saturday night, then moves into Wyoming. Snow may linger through the day on Monday. I'm forecasting light to moderate accumulations.
