Minneapolis, Minnesota – A surge of Arctic air late this month could bring one of the coldest stretches of January to Minnesota and Wisconsin, with temperatures expected to plunge well below seasonal averages as the month comes to a close.
According to the National Weather Service Climate Prediction Center, outlooks for January 17 through January 30 strongly favor below-normal temperatures across the Upper Midwest. The broader pattern supports repeated intrusions of Arctic air, allowing cold conditions to intensify and persist rather than easing after a brief cooldown.
In Minnesota, the coldest air is expected to arrive early in the pattern, with prolonged stretches of bitter cold possible across much of the state. Extended exposure could strain heating systems, increase the risk of frozen pipes, and create dangerous conditions for anyone spending extended time outdoors. Gusty winds may further amplify wind chill concerns, especially across open and rural areas.
Across Wisconsin, the cold air is expected to settle in quickly as well, spreading from north to south. Even in areas that see limited snowfall, icy conditions may develop due to overnight refreezing, particularly during morning and evening commutes along major corridors such as I-94, I-35, and I-90.
Officials urge residents across both states to prepare ahead of time by checking heating systems, insulating exposed plumbing, and limiting time outdoors during the coldest periods. While snowfall may vary by location, the cold itself is likely to be the most impactful hazard late this month.
The Arctic pattern is expected to remain active through the final days of January, and additional cold weather advisories or warnings may be issued as confidence increases closer to each surge.
