Winter Storm Weather Forecast: Major March Snowstorm Brings Blizzard Conditions and Dangerous Travel Hazards
MINNEAPOLIS — A historic and powerful late-season winter storm continues to hammer the Upper Midwest today, Sunday, March 15, 2026, dropping heavy snow and whipping up 60 mph winds that have effectively paralyzed travel across much of southern Minnesota and western Wisconsin. The National Weather Service (NWS) has raised warnings to full blizzard status for a broad corridor of the region, warning that the “one-two punch” of intense snowfall rates and near-hurricane-force gusts is creating a life-threatening environment.
Snowfall Totals Climb as “Bomb Cyclone” Deepens
The storm, which meteorologists are describing as a “bomb cyclone” due to its rapid intensification over Iowa and Wisconsin, is pulling deep moisture from the south and colliding with a plunge of Arctic air. As of Sunday morning, snowfall reports indicate the sheer intensity of the system’s core.
- Wabasha: 15 inches
- Rochester: 11 inches
- Red Wing: 11 inches
- Twin Cities Metro: Totals between 7 and 10 inches, with an additional 6 to 10 inches forecast through the evening.
In some areas of northeastern Wisconsin and Michigan’s Upper Peninsula, localized accumulations are projected to reach a staggering 36 inches by Monday afternoon due to lake-effect enhancement.
Dangerous Travel: “No Travel Advised” Across South-Central Minnesota
The Minnesota Department of Transportation (MnDOT) has issued a “No Travel Advisory” for a massive stretch of the state, including all state highways and Interstate 90 in south-central Minnesota. Visibility has been reported as near-zero in many locations, with whiteout conditions making it impossible for snowplows to maintain clear paths safely.
“Blowing snow and strong winds are creating blizzard conditions and making travel difficult,” MnDOT officials stated. “Conditions are expected to remain difficult today until they gradually improve on Monday.”
The Minnesota State Patrol has already responded to more than 250 crashes and spin-outs since the snow began on Saturday night. Gov. Tim Walz has signed an executive order authorizing the Minnesota National Guard to support emergency operations, placing armories in Owatonna, Redwood Falls, Fairmont, and Albert Lea on high alert for rescue missions.
Aviation and Infrastructure Impact
The “meltdown” extends beyond the highways. Minneapolis-St. Paul International (MSP) has become the epicenter of air travel chaos, with over 700 flight cancellations reported by midday Sunday. Chicago’s O’Hare and Midway airports are also facing significant disruptions as the storm sweeps through the Great Lakes.
In addition to travel woes, the heavy, wet nature of the snow combined with 60–70 mph gusts has downed transmission lines. Over 1.1 million Americans across the central U.S. were reported to be without power as of Sunday afternoon, with the largest outages concentrated in the path of the storm from the Plains to the Great Lakes.
Outlook: Arctic Plunge to Follow
While the snow is expected to taper off late Sunday into early Monday, the danger will not pass immediately. A “soul-crushing” Arctic plunge is forecast to follow the storm, with wind chills expected to drop to -10°F in Minneapolis and Chicago.
Residents are urged to shelter in place and keep emergency survival kits ready. Although the official start of spring is only days away, the Midwest remains locked in a historic winter grip that experts suggest could be the region’s most severe late-season event in a decade.

FAQs: March 2026 Blizzard & Winter Storm
1. Which areas are under a Blizzard Warning?
The most critical warnings are in effect for central and southern Minnesota, northern Iowa, and western Wisconsin. This includes cities like Minneapolis, St. Paul, Rochester, Mankato, and Eau Claire.
2. How much more snow is expected?
While many areas have already seen 10–15 inches, an additional 5 to 10 inches is forecast for the Twin Cities through Sunday night. Parts of the North Shore and Michigan’s Upper Peninsula could see totals exceeding 36 inches due to lake-effect enhancement.
3. Are the highways closed?
While not all interstates are officially closed, MnDOT has issued a “No Travel Advisory” for most of southern Minnesota, including I-90 and I-35 south of the metro. In South Dakota, segments of I-29 and I-90 have been shut down due to zero visibility.
4. Is the Minneapolis-St. Paul (MSP) Airport open?
The airport remains open, but operations are severely limited. As of Sunday evening, over 700 flights have been canceled. Most major airlines (Delta, United, Sun Country) have issued travel waivers for rebooking.
5. When will the storm end?
Snow is expected to taper off late Sunday night into early Monday morning. However, blowing and drifting snow will remain a major hazard through the Monday morning commute as winds continue to gust up to 60 mph.
6. What should I do if I lose power?
Heavy snow and high winds have already knocked out power to over 1.1 million people across the Midwest. If your power goes out, keep your refrigerator closed, use flashlights instead of candles, and never run a generator inside your home or garage.
