SnoCountry SnoCast: Northern Pattern Shift

A changing weather pattern across the West will alter storm tracks across Canada, while several cold shots hit the East.


Western U.S. & Canada

On Wednesday, Nov. 22, mixed precipitation will be soaking areas from Oregon to the north. A record warm “bubble” of air will center itself across the southern Rockies. Snow will fall mainly above 8,000 feet through Thanksgiving Day.

Colder and drier air will work in Friday, then snowfall will occur Saturday and Sunday (Nov. 25-26) with nearly-constant precipitation at lower levels. Most snowfall will stay north of California to Colorado, heaviest in western Canada and Washington/Oregon.

Monday we’ll get a break before Tuesday/Wednesday heavier snowfall should push from Canada to Oregon, farther south to California, Utah, and to Colorado as a cooler pattern returns. For the week, snowiest spots include Alberta’s Lake Louise and Marmot Basin as well as Washington’s Mt. Baker.

Midwest, Eastern U.S. & Canada

Several cold shots are on the way through the end of the month, each with light, fluffy snow accumulation and a little bit of rain. The first cold front moves through Wednesday night, followed by a quiet and seasonably-cool Thanksgiving Day and Friday. The next cold front arrives Saturday with a rain/snow mix and light snowfall. Heavier lake effect snow showers will fall Sunday-Monday (Nov. 26-27) and the next front arrives Wednesday. It should remain plenty cool enough to make snow.

Natural snow will be light, on the order of 2-6”, isolated 8” for the U.S. but 12” and more in parts of eastern Canada. Heaviest potential snow in the Northeast looks to be in New York’s Whiteface Mountain. The World Cup weather in Killington, Vermont will be:

  • Friday: Partly sunny, in the 30's
  • Saturday: Cloudy with a light mix, near 40 degrees 
  • Sunday: Windy with snow showers, in the 20's
