We're seeing bigger temperature swings now. The storm track is still active with a few different large storms, but the "warm before the storm" is significant. The Northeast is a great example of this on Friday–Saturday. A large storm will flood the Northeast with warm temps and mostly rain on Friday, even at the ski areas, then colder air pours in Friday night into Saturday changing the rain to snow. Another warm storm with rain hits on Tuesday–Wednesday.
Out West, the northern Rockies are in for a mix of rain and snow Friday, Saturday, Sunday and Monday at the ski areas of Wyoming, Montana and Idaho.
Northeast: Rain on Friday changes to light snow Friday night into early Saturday. Sunday looks dry and colder. Another round of rain moves in on Tuesday changing to light snow on Wednesday. A bunch of resorts are scheduled to close this Sunday, so this may be your last chance! Take a look at Killington, Jay Peak, Mad River Glen, Sugarbush and Sugarloaf.
Rockies: A mix of rain and snow on Friday, Saturday, Sunday and Monday in Montana, Idaho and Wyoming. Snow amounts look moderate in total over those four days. Take a look at Big Sky and Grand Targhee before they close.
Colorado: Mild and dry on Saturday and Sunday. A wet southern storm could move in on Monday with mostly rain and very high elevation snow. Ski Vail, Monarch, Loveland, Keystone, Breckenridge, Winter Park, Steamboat and Aspen before they close.
