Cold air, wintry winds and even the first snow of the season will sweep from Montana to Minnesota during the middle of the week.
The first big blast of arctic air will arrive in the Canada Prairies and Rockies during the first part of the week and then cross the border into Montana and the Dakotas at midweek, accompanied by gusty winds and even the first snow of the season for many areas.
According to Expert Senior Meteorologist Alex Sosnowski, "Rain showers will become mixed with and change to snow moving southward along the Alberta foothills Tuesday and Tuesday night, where a few centimeters of snow can accumulate."
Tuesday night into Wednesday, the cold push and snow will arrive in Montana.
"Great Falls and Billings can pick up a couple of inches of snow," Sosnowski said, "This will be the first snow of the season for some areas away from the high country."
The cold push and rain changing to snow will then reach eastward over portions of the Dakotas and northwestern Minnesota spanning Wednesday and Thursday.
A swath of accumulating snow, averaging an inch or two will redevelop over parts of central and eastern North Dakota, northwestern Minnesota and neighboring portions of Manitoba and northwestern Ontario.
The cities of Grand Forks, N.D., and International Falls, Minn., could be in this swath.
The early season outbreak will easily bring the chilliest weather of the season so far to these areas and will be accompanied by a period of gusty winds. Gusts can top 40 mph.
"Daytime AccuWeather.com RealFeel® temperatures likely will hold in the 20s and 30s over much of Montana, the Dakotas, and parts of Wyoming and Minnesota for a day or two," Sosnowski stated, "In some areas they can dip into the teens for a time."
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 second push of cold air appears to be in the cards for the end of the week and next weekend. Another bout of snow will likely accompany it over the Rockies, this time reaching farther south into Colorado.
This projected weather pattern fits with the connection between one to two weeks after tropical systems curve before hitting the coast of Asia in the Pacific, that colder air pushes into part of the northern United States.
The Pacific Tropical Storm Ewiniar more or less did this east of Japan over this past week, and Jelawat is following suit, scraping Japan along the way.
It appears that some of this chilly air will finally reach the Midwest and Northeast next weekend.
"It is possible that next push of cold air brings the first snow showers of the season to parts of the Great Lakes region," Sosnowski said.
