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. Residents across the region are advised to take precautions as outlined by local authorities and the National Weather Service.

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.

Residents in these areas are strongly advised to delay travel unless absolutely necessary and to equip their vehicles with winter survival kits containing blankets, tire chains, and other essentials.

In Wells and Foster Counties, North Dakota, including the cities of Fessenden, Carrington, and Harvey, the storm is forecasted to bring 4 to 7 inches of snow. Blowing snow could create near-blizzard conditions, making travel extremely dangerous, especially during the Thursday morning commute.

Similar conditions are expected in north-central and northwest North Dakota, including areas such as Rolla, Rugby, Minot, and Bottineau. Snowfall accumulations are projected to range from 5 to 8 inches, accompanied by strong winds that will reduce visibility. Residents in these regions are urged to delay travel plans and monitor weather updates for changing conditions.

Several areas in Minnesota are also experiencing significant snowfall and hazardous conditions. Crow Wing, Pine, South Aitkin, and Cass Counties, which include cities such as Brainerd and Pine City, are expected to receive 4 to 6 inches of snow.

The storm is forecasted to persist until midnight CST Thursday night, causing slippery roads and challenging travel conditions. Residents are urged to avoid unnecessary travel and to ensure their vehicles are equipped for winter weather.

In Carlton, Southern St. Louis, and Southern Lake Counties, including Duluth, Two Harbors, and Silver Bay, snow accumulations of 4 to 6 inches are expected, with higher totals in elevated areas along the North Shore.

Hazardous conditions are anticipated during both the morning and evening commutes. Emergency kits should be prepared, and motorists are encouraged to monitor the Minnesota 511 system for road condition updates.

Central and east-central Minnesota, including cities such as Minneapolis, St. Paul, Alexandria, and Elk River, are bracing for snowfall accumulations between 5 and 7 inches. Hazardous road conditions are likely to disrupt commutes throughout Thursday, and residents are advised to avoid travel unless necessary.

In Wisconsin, the storm is expected to bring heavy snow across multiple counties. Bayfield County, including Washburn and the Apostle Islands National Lakeshore, is predicted to receive between 5 and 8 inches of snow.

Hazardous road conditions are expected throughout Thursday, making travel dangerous. Residents are urged to monitor weather alerts and avoid travel if possible.

Clark, Taylor, Buffalo, and Jackson Counties, which include cities such as Medford, Alma, and Black River Falls, could see snow accumulations of 5 to 8 inches. The storm is forecasted to persist until early Friday morning, with slippery roads and reduced visibility making travel difficult.

Similar conditions are expected in Door, Manitowoc, and Kewaunee Counties, where snowfall totals may range from 7 to 10 inches, with localized amounts reaching up to 12 inches.

Hazardous conditions are likely to impact commutes Thursday evening and Friday morning, and residents are strongly encouraged to delay travel.

In Marathon, Portage, Waushara, and Wood Counties, including cities such as Wausau and Wisconsin Rapids, snow accumulations are projected to range from 5 to 8 inches. Travel is expected to become treacherous, with snow-covered roads creating dangerous conditions for motorists. Similar accumulations are forecasted for Barron, Polk, and St. Croix Counties, including cities such as Hudson, Chippewa Falls, and Menomonie.

The storm will impact the region until early Friday morning, and drivers should carry emergency supplies and avoid travel unless necessary.

Winnebago, Brown, Shawano, and Waupaca Counties, including cities such as Green Bay, Appleton, and Oshkosh, are also under a winter storm warning. Snow accumulations between 5 and 8 inches are expected, with travel disruptions likely through Friday morning. Residents in these areas are advised to prepare for significant disruptions and avoid travel during the storm.

With winter storm warnings already creating hazardous conditions across Minnesota, North Dakota, and Wisconsin, it is important to understand the broader context of winter weather and the significance of these warnings as the season progresses.

As residents across the region contend with this major storm, it’s worth noting that the winter solstice, which officially marks the beginning of winter, will occur at 3:21 a.m. CST on Saturday, December 21. On this day, the Northern Hemisphere will experience its shortest amount of possible daylight.

Interestingly, the earliest sunset already occurred earlier this month, and the latest sunrise is yet to come near the end of December.

The winter solstice happens when the Earth’s axis is tilted 23.5 degrees away from the Sun. Despite the proximity to the Sun during this period, the low angle of sunlight results in colder temperatures. This phenomenon highlights why the coming months will likely bring continued storms and challenges, requiring residents to remain vigilant.

The National Weather Service issues different types of warnings based on the severity and expected impacts of winter weather.

A “Winter Storm Warning,” such as the one currently in effect, signifies heavy snow accumulation of at least 6 inches within 12 hours or 8 inches within 24 hours. Alternatively, it may be issued when sleet accumulation is expected to reach half an inch.

Other warnings include the “Ice Storm Warning,” issued when at least 1/4 inch of ice accumulation is expected. The “Blizzard Warning” is issued when visibility drops below 1/4 mile due to snow, with winds of at least 35 mph lasting for three consecutive hours.

These categories of warnings provide a critical context for understanding the risks associated with severe winter weather.

The ongoing winter storm has demonstrated the potential for widespread disruption across Minnesota, North Dakota, and Wisconsin. As residents prepare for additional snowfall and dangerous travel conditions, it is vital to heed the warnings issued by the National Weather Service and take appropriate precautions.
