A powerful winter storm has paralyzed much of the Upper Midwest and Great Lakes region, bringing blizzard conditions, dangerous travel, and widespread disruptions just as millions prepare for Thanksgiving. By Wednesday morning, highways were buried under heavy snow, with winds reaching 40 to 45 miles per hour. In Minnesota, Wisconsin, and Michigan’s Upper Peninsula, snowfall totals approached 30 inches, turning roads into treacherous paths and airports into hubs of chaos.
Storm Systems and Warnings
Two major storm systems are responsible for the extreme weather. The first, sweeping across the Great Lakes, is producing lake-effect snow at rates of 1 to 2 inches per hour. Wind gusts up to 45 mph have created whiteout conditions, prompting blizzard warnings for more than 13 million residents in Minnesota, Wisconsin, and Michigan. The National Weather Service warns that travel should be restricted to emergencies only, as visibility drops to near zero and snow drifts block roads.
Air Travel Disruptions
Airports across the country have been severely impacted. By Wednesday afternoon, over 2,300 flights were delayed nationwide. Chicago O’Hare International Airport, one of the busiest in the U.S., experienced a ground stop early Wednesday due to snow and ice, with subsequent delays cascading through the national flight network. Ground stops were also issued at LaGuardia, Newark, and JFK airports in New York. Airlines are bracing for continued disruptions as the storm moves eastward, coinciding with peak Thanksgiving travel.
Roadway Hazards and Fatalities
The storm’s impact on roadways has been equally severe. Between Tuesday afternoon and Wednesday morning, more than 250 vehicle crashes were reported, with at least 30 resulting in injuries. Over 30 semi-trucks jackknifed on Minnesota highways, and major interstates, including I-94 and I-29, were closed for extended periods. A 69-year-old man was killed in Alden Township, Minnesota, after being crushed by a snow-laden tree that fell during the storm, highlighting the deadly risks posed by heavy, wet snow and strong winds.
Lake-Effect Snow and Regional Impact
As the first system moves out, a historic lake-effect snow event is developing across the Great Lakes Snowbelt. Areas downwind of Lake Erie and Lake Ontario are expected to receive up to 20 inches of snow, with blizzard conditions creating hazardous travel situations. The worst of the snow is forecast for Thanksgiving Day, affecting Ohio, Pennsylvania, western New York, and the Tug Hill Plateau.
Power Outages and Arctic Air
The storm has also caused widespread power outages, with more than 71,000 customers affected across Wisconsin, Michigan, and Indiana. Strong winds have led to tree damage and power line failures, leaving utilities on high alert. After the storms pass, a surge of Arctic air will sweep across the nation, bringing temperatures 10 to 20 degrees below normal and dangerous wind chills.
Traveler Protections and International Complications
International travelers have faced extended delays and cancellations, with limited rebooking options due to system-wide disruptions. Unlike in Europe, U.S. passengers currently receive limited compensation for weather-related delays, as a proposed rule requiring airlines to provide compensation was withdrawn on November 14, 2025. American passengers rely on airline discretion for meal vouchers and occasional hotel accommodations during extended delays.
