Cold air and wintry winds appear to be taking aim for part of the Rockies and Plains next week. Snow could also accompany the blast in some locations.
While the details of the wintry weather are far from clear at this stage, a push of cold air will drive southward along the eastern slopes of the Canada Rockies early next week.
Snow is most likely to fall over parts of the Canada Rockies and in portions of Alberta east of the Rockies Sunday night and Monday.
From there, the cold push and at least spotty snow showers are likely to continue southward into Montana and the northern Plains of the United States Tuesday and Wednesday.

The early-season outbreak will easily bring the chilliest weather of the season so far to these areas and will be accompanied by wind.
It is possible that some areas have daytime AccuWeather.com RealFeel® temperatures in the 20s and 30s for a couple of days.

The chill from this particular outbreak will take some time to get to the Great Lakes region and may have to wait for another push to do so.
This projected pattern fits with the connection that approximately 7 to 14 days after tropical systems curve before hitting the coast of Asia in the Pacific, that colder air pushes into part of the northern U.S.
Tropical Storm Ewiniar has more or less done this east of Japan over this past week, and Jelawat is following suit.
