A severe winter storm is unleashing heavy snow and strong winds across the Upper Midwest, disrupting travel and prompting widespread weather alerts for affected areas.

A massive winter storm has prompted the National Weather Service to issue warnings for Minnesota, North Dakota, and Wisconsin, affecting over 30 counties.

The warnings forecast heavy snow, strong winds, and hazardous travel conditions, with impacts expected to last through Thursday evening (December 19) and into Friday morning (December 20) in some areas.

In Minnesota and North Dakota, heavy snow and high winds are creating hazardous conditions. In northwest Minnesota and northeast and southeast North Dakota, including cities such as Grand Forks, Devils Lake, Crookston, and Mahnomen, total snow accumulations are predicted to range from 4 to 8 inches. Winds gusting as high as 40 mph are likely to result in blowing snow and significantly reduced visibility.

These conditions are expected to persist until 6 p.m. CST Thursday, impacting both morning and evening commutes. Travelers are advised to carry emergency kits, including a flashlight, food, and water, and to check road conditions by calling 511.

Central and west-central Minnesota and southeast North Dakota are also under a winter storm warning. Cities such as Fargo, Moorhead, Detroit Lakes, and Wadena are preparing for snow accumulations between 3 and 7 inches. Whiteout conditions, caused by strong winds and blowing snow, are expected to make travel treacherous and potentially life-threatening.
