Cold air dominates most of the United States and Canada through Christmas, leading to favorable conditions for snowfall in many areas.
Western U.S. & Canada
Fresh snow from Tuesday (Dec. 19) to Friday (Dec. 22) will shift to much colder and drier weather by Christmas weekend. A low pressure system in the Pacific Northwest has dominated the mountains of Washington, Oregon, Idaho, and northern California. This system will move southeast, clearing out and dissipating by Thursday. It will be replaced by a strong high pressure system that will stick around through Christmas. Some winners include Bridger Bowl in Montana and Lookout Pass in Idaho.
With this high pressure will come bitterly cold temperatures, seeping down from interior Canada and through the Rocky Mountains. Parts of Wyoming could be as low as -22 °F on Christmas Eve.
The next snow will arrive late Christmas day, moving across the West through Wednesday with potentially powerful accumulations.
Eastern U.S. & Canada
A series of storm systems will bring 3-8 inches of fresh snow across the Northern Plains and Great Lakes Thursday to Saturday. Hardest-hit states include Michigan and Wisconsin, including Granite Peak. The Northeast will get in on snow Friday with 2-6 inches across northern New York and northern New England, including Jay Peak. Precipitation will transition to mostly rain Saturday across the Northeast as temperatures creep above freezing. A cold front sweeping through Sunday will revive lake-effect and upslope snow showers in the favored regions. Additionally, certain weather models hint that New England may see a coastal system for Christmas with possible widespread snow accumulations.
Regardless, Christmas day should feature temperatures ranging from 15 to 25 across the mountains from Maine to West Virginia while temperatures plummet to near and below zero across the Upper Great Lakes.
