EXTREME WEATHER OUTLOOK

Winter Storm Map Discussion

We're watching the potential for early-season snow across parts of the northern Rockies and Canadian Rockies this weekend and into early next week. Some of the higher elevations could receive more than a foot of snow as colder air moves southward from Canada and interacts with an approaching storm system.

A surge of cold air will push southward from the Canadian Prairies into Montana and the northern High Plains. As that colder air settles in, upslope flow along the mountains, combined with the developing storm system, could produce periods of moderate to heavy snow, especially across the higher elevations of the Rockies.

For many locations, this could be the first measurable snowfall of the season, particularly in the higher terrain around the Canadian and northern Rockies. Snowfall amounts will vary considerably with elevation, but some of the favored mountain areas could see significant accumulations.

It's certainly a sign that we're beginning to make the transition toward the colder half of the year, with the first real taste of winter showing up across the northern Rockies.
