The watch extended beyond the metro, covering counties such as Brown, Chippewa, Cottonwood, and Stearns, among others. Forecasters emphasized that the storms could produce not only tornadoes but also significant hail and wind damage. In southwestern Minnesota, a separate tornado warning was issued earlier in the day for Pipestone and Murray counties, expiring at 3:45 a.m. CDT after radar indicated rotation near Pipestone.
Storms bring chaos to Twin Cities metro
By mid-afternoon, the Twin Cities metro area was at the heart of the severe weather event. A tornado warning was issued at 2:25 p.m. CDT, covering downtown Minneapolis and surrounding suburbs, including Eden Prairie and Burnsville. The National Weather Service reported a rotating storm near the Minneapolis-St. Paul International Airport, prompting travelers and airport staff to seek shelter. Paul Huttner, MPR News chief meteorologist, described a “hook echo” on radar, a telltale sign of potential tornado formation, though no funnel clouds were sighted.
Power outages affected over 2,500 customers in the metro area, according to Xcel Energy’s outage map. The outages disrupted traffic signals and businesses, compounding the challenges of navigating stormy conditions. Residents in northern suburbs like Blaine and Coon Rapids were advised to remain cautious as the storm moved northeast at 40 mph.
- Key impacts in the Twin Cities:
- Power outages disrupted daily activities for thousands.
- Traffic delays mounted as heavy rain reduced visibility.
- Airport operations faced temporary halts, affecting flights.
- Schools dismissed students early or canceled after-school activities.
Hail and winds threaten property and safety
Large hail emerged as a significant concern across Minnesota on Thursday. Meteorologists warned of hailstones measuring 1-2 inches in diameter, capable of denting vehicles and damaging roofs. In southern Minnesota, earlier storms had produced ping-pong-ball-sized hail, and forecasters expected similar conditions in the metro area. The hail threat was particularly acute in areas under an enhanced risk (level 3 of 5) for severe weather, including eastern parts of the Twin Cities and western Wisconsin.
Strong winds, with gusts up to 70 mph, posed additional risks. The National Weather Service noted that such winds could topple trees and power lines, exacerbating outages. In rural areas, farmers worried about crop damage, as high winds and hail could devastate fields nearing harvest season. Residents were urged to secure outdoor items and avoid parking under trees during the storm’s peak.
Wisconsin feels the storm’s reach
As the storm system progressed, a tornado warning was issued for northwest Pierce County in Wisconsin until 3:15 p.m. CDT. The warning targeted areas southeast of Prescott, where radar detected a storm with significant rotation. Meteorologist Paul Huttner emphasized the storm’s “distinct hook echo,” indicating a high potential for tornadoes. The warning came as the storm crossed state lines, affecting communities near the Minnesota-Wisconsin border.
Wisconsin residents, particularly in River Falls and surrounding areas, were advised to take cover in basements or interior rooms. The storm’s rapid movement, clocked at 35-45 mph, left little time for preparation. Local emergency services activated sirens and disseminated alerts via text and radio, urging residents to stay indoors.

Airports and transportation face disruptions
The Minneapolis-St. Paul International Airport, a major hub, experienced significant disruptions as a severe-warned thunderstorm passed over Terminal 1 on Thursday afternoon. Airport authorities halted ground operations, delaying flights and stranding passengers. Travelers were directed to safe areas within terminals, with some taking shelter in restrooms and stairwells.
Road travel was equally challenging, with heavy rain and low visibility snarling commutes across the Twin Cities. The Minnesota Department of Transportation reported minor accidents and road closures due to fallen branches and debris. Public transit systems, including Metro Transit buses and light rail, operated on delayed schedules as operators prioritized safety.
- Transportation impacts:
- Flight delays and cancellations at MSP Airport.
- Road closures due to debris and flooding.
- Public transit delays across the metro area.
- Increased risk of accidents due to slick roads.
Schools and businesses take precautions
Schools across Minnesota implemented safety measures as the storms approached. Several districts, including those in Hennepin and Ramsey counties, announced early dismissals or canceled after-school activities. Administrators cited the risk of severe weather during dismissal times, particularly for students relying on buses. Some schools activated shelter-in-place protocols, directing students to interior hallways away from windows.
Businesses, particularly in retail and hospitality, adjusted operations. Outdoor events, such as farmers’ markets and festivals, were postponed or canceled. Restaurants with patios closed outdoor seating, while construction sites halted work due to high winds and lightning risks. Employers encouraged remote work where possible, reducing the number of commuters exposed to hazardous conditions.
Rural communities brace for impact
In rural Minnesota, communities like Benson and Morris faced their own challenges. A funnel cloud was reported southwest of Benson in Swift County around 1:15 p.m., followed by another sighting southeast of Morris. While no tornadoes were confirmed, the sightings heightened anxiety among residents. Farmers in these areas rushed to protect livestock and equipment, with some moving animals to sheltered barns.
The National Weather Service’s Sioux Falls office issued a severe thunderstorm warning for Lyon County and surrounding areas early Thursday, citing quarter-sized hail and wind gusts up to 60 mph.

Historical parallels to Minnesota’s storms
Minnesota has a history of severe weather, with notable tornado outbreaks shaping its preparedness strategies. On June 17, 2010, the state experienced its largest single-day tornado event, with 48 tornadoes touching down. More recently, on August 29, 2024, six tornadoes struck central and southern Minnesota, including an EF1 near Andover. These events underscored the importance of robust warning systems and community readiness.
Thursday’s storms, while not yet producing confirmed tornadoes, echoed the unpredictability of past events. Meteorologists noted that the current weather pattern, driven by a warm, moist air mass colliding with a cold front, mirrored conditions that fueled previous outbreaks. The state’s investment in weather infrastructure, including Doppler radar and emergency sirens, has improved response times compared to decades past.
Community response and preparedness
Minnesota’s residents demonstrated resilience in the face of Thursday’s storms. Emergency management agencies activated command centers, coordinating with local fire and police departments. Community shelters opened in vulnerable areas, providing safe havens for those in mobile homes or older structures. Volunteers with organizations like the American Red Cross stood ready to assist with potential storm damage.
Public awareness campaigns, such as Severe Weather Awareness Week held April 7-11, 2025, have equipped Minnesotans with knowledge of safety protocols. Residents were reminded to:
- Seek shelter in a basement or interior room on the lowest floor.
- Avoid windows and exterior walls during storms.
- Monitor weather alerts via NOAA Weather Radio or mobile apps.
- Prepare an emergency kit with food, water, and flashlights.
- Develop a family communication plan for severe weather events.
Ongoing threats as storms move eastward
As Thursday afternoon progressed, the severe weather threat shifted eastward, with storms expected to impact western Wisconsin and parts of Iowa. The National Weather Service forecasted continued risks of hail and wind gusts through the evening, with the tornado threat diminishing after sunset. Forecasters urged residents to remain vigilant, as isolated storms could still produce hazardous conditions.
In the Twin Cities, the worst of the storm appeared to have passed by 3 p.m., though scattered showers and thunder lingered. Meteorologists warned that additional storms could develop later in the evening, particularly in areas under a slight risk (level 2 of 5). The rapid pace of the storms, moving at 40-50 mph, underscored the need for real-time updates and quick decision-making.
Residents urged to stay informed
Local authorities emphasized the importance of staying informed as the weather event unfolded. The National Weather Service encouraged residents to monitor multiple sources, including television, radio, and mobile apps, for the latest updates.
