I may not be an expert on the weather in the affected regions, but isint it kind of early for a major snow like that? I can understand
high-elevations on mountains to be covered early in the season, but not this early in major areas?
I'm not entirely sure about Wyoming and the Dakotas, but in northwestern Montana and Alberta, it's not common, but it happens every few years.
We get a pattern here, usually in midwinter, where a low pressure system goes through central Alberta, early on we get mild weather from the coast,
but as the system moves East, it changes to an arctic front. The temperatures here have dropped as much as 55C in less than 24 hours.
A second type of pattern in winter here is a "chinook" where the temperature has been known to rise as much as 10 degrees in 5 minutes, and New
Years day can be as nice as 25C.
There's also freak snowstorms that occur in July and August. Those are rare.
