Illinois, Wisconsin, and Minnesota Brace for Major Winter Storm With Blizzard Conditions, Dangerous Travel, and Powerful Winds Into Monday

ILLINOIS / WISCONSIN / MINNESOTA — A major winter storm is intensifying across the Upper Midwest on Sunday and will continue into early Monday, bringing heavy snowfall, blizzard conditions, and dangerously strong winds that could make travel extremely hazardous across large parts of Minnesota, Wisconsin, and northern Illinois.

Forecast data from the National Weather Service shows a rapidly strengthening system capable of producing several inches of snow, localized totals exceeding 10 inches, and wind gusts strong enough to create whiteout conditions, particularly across eastern Minnesota and western Wisconsin.

Blizzard Warnings and Winter Storm Warnings Expanded Across the Region

Blizzard Warnings remain in effect across central and southern Minnesota, where the combination of heavy snowfall and sustained strong winds is expected to sharply reduce visibility.

At the same time, Winter Storm Warnings cover eastern Minnesota and much of western Wisconsin, signaling prolonged snowfall, blowing snow, and dangerous road conditions through Sunday night.

Forecasters note that areas under Blizzard Warnings may experience near-zero visibility for extended periods, making travel potentially life-threatening.

Snowfall Totals Increasing, With Localized 10+ Inches Possible

Updated snowfall projections show heavier totals than earlier forecasts, with amounts trending upward overnight.

Key snowfall expectations include:

• 7–10 inches across parts of eastern Minnesota and western Wisconsin
• 5–8 inches extending outward from the heaviest band
• Localized totals over 10 inches possible where narrow snow bands set up

Meteorologists caution that while confidence is high in heavy snowfall, the exact placement of the most intense bands remains uncertain, which could cause sharp differences in totals over short distances.

Strong Winds to Create Whiteout Conditions and Drifting Snow

Wind forecast charts show strong and persistent winds throughout Sunday and into early Monday, with gusts frequently exceeding 40 mph in warning areas.

These winds will:

• Cause blowing and drifting snow
• Rapidly reduce visibility on highways and rural roads
• Make snow removal difficult even after snowfall slows

Officials warn that roads cleared earlier in the day may quickly become impassable again due to drifting snow.

Illinois and the Great Lakes Region Face Hazardous Travel

While the most extreme snowfall remains north and west, northern Illinois and the Great Lakes region are expected to experience strong winds and periods of reduced visibility, especially near Lake Michigan.

Travel across interstate corridors connecting Illinois, Wisconsin, and Minnesota may be significantly disrupted, with delays and closures possible as conditions worsen overnight.

Drivers are urged to reconsider travel plans and monitor local alerts closely.

Officials Urge Residents to Avoid Travel and Prepare Emergency Kits

Transportation agencies across the region are urging residents to:

• Avoid non-essential travel
• Carry emergency supplies if driving is unavoidable
• Check road conditions before departure

Emergency preparedness guidance emphasizes keeping warm clothing, blankets, food, water, flashlights, and phone chargers in vehicles during winter storms of this magnitude.

Storm Expected to Shift East After Monday Morning

Forecast models indicate the system will gradually move eastward after early Monday, allowing conditions to slowly improve across the Upper Midwest.

However, lingering snow, strong winds, and dangerously cold air behind the system may continue to affect travel and outdoor activities into Monday afternoon.

If you’re heading to concerts, venues, or holiday events this weekend or early Monday, check local conditions before leaving and allow extra time — or consider postponing plans until conditions improve.
