AccuWeather Global Weather Center – Cold air will plunge into the north-central United States by week’s end, possibly bringing the first snowflakes of the season to some communities.

People across the region may be breaking out winter attire and turning on the heaters for the first time this year.

A direct discharge of Arctic air will sweep through the Canadian Prairies and into the far northern Plains late this week and into the weekend, according to AccuWeather Senior Meteorologist Brett Anderson.

Cool Air Advances

The cold sweep reached the northern Plains on Thursday and is forecast to plunge across the Great Lakes and a portion of the central Plains during Thursday night and Friday.

Compared to earlier this week, temperatures will be slashed by up to 20 degrees Fahrenheit across much of Montana, the Dakotas and northern Minnesota, with highs projected to stay in the 40s and lower 50s.
