Blizzard Conditions Slam Upper Midwest as Same System Puts 11.5 Million Under Warnings and Brings Monday Tornado Threat to Mid-Atlantic
A powerful storm has slammed the Upper Midwest with blizzard conditions — parts of Wisconsin and Michigan have seen as much as 2 feet of snow with another foot possible in Upper Michigan — prompting school and commuting disruptions, a Minnesota no‑travel advisory, deployment of the National Guard and hundreds of flight cancellations at Minneapolis–Saint Paul and elsewhere. The system has placed about 11.5 million people under blizzard warnings (4.3 million more under winter‑storm warnings) and contributed to more than 2,000 flight cancellations nationwide while spawning a severe‑weather threat for the Mid‑Atlantic Monday. The NWS warns of a moderate‑risk corridor from South Carolina to Maryland — including Raleigh, Richmond and Washington, D.C. — where widespread damaging winds and several tornadoes are possible, even as forecasters note an unusually early Western heat wave and expanding freeze‑warning wind chills into the Gulf Coast by Tuesday.
📌 Key Facts
- Nationwide alerts tied to the system: 11.5 million people under blizzard warnings, 4.3 million under winter storm warnings, and 20.6 million under an extreme heat watch; meanwhile an unusually early Western heat wave is expected to last much of the week with potential record highs and heightened wildfire risk.
- The Upper Midwest is experiencing continued blizzard conditions in parts of Wisconsin and Michigan, with as much as 2 feet of snow already fallen and another foot or more expected in Upper Michigan, causing school closures and major commuting disruptions in cities such as Milwaukee and Marquette.
- Minnesota officials issued a state no‑travel advisory for southern counties and Gov. Tim Walz authorized deployment of the Minnesota National Guard to support emergency operations.
- The storm has heavily impacted air travel: more than 2,000 flights canceled nationwide as of Monday, including over 600 cancellations at Minneapolis–Saint Paul and additional cancellations at Detroit.
- The National Weather Service says the severe line will move from the Mississippi, Tennessee and Ohio valleys into the Appalachians and onto the East Coast, producing severe thunderstorms with widespread damaging winds and several tornadoes; the greatest risk is a corridor from South Carolina to Maryland (including Raleigh, Richmond and Washington, D.C.) for the strongest damaging winds and tornadoes Monday afternoon.
- Local protective actions reflect the threat level in the Mid‑Atlantic: officials have closed schools in Raleigh and Chapel Hill and taken other measures to prepare for Monday’s severe storms.
- By Tuesday morning, dangerously cold conditions are forecast to follow the system, with sub‑freezing wind chills and freeze warnings extending into the Gulf Coast and Florida Panhandle and across parts of Arkansas, Oklahoma, Louisiana and Texas.
