Memorial Day Severe Weather Forecast for Minnesota


While there is some uncertainty about our overall severe risk due to persistent morning clouds and showers, there is still a high likelihood of severe weather late Monday in Minnesota with strong isolated tornadoes possible, as well only wind gusts over 75 mph and very large hail.

The Twin Cities Metro is now at Level 3 risk for large hail, damaging winds and isolated tornadoes, while large parts of central and western Minnesota face Level 4 risk, including including a tornado threat. Storms will begin to develop in northeastern South Dakota and southwestern Minnesota by Monday afternoon and move quickly to the northeast.

Late morning until noon brings a few crucial hours of tranquility that are needed for the atmosphere to recharge for severe weather to form late Monday. The longer the clouds persist, the lower our potential serious risk. For now, severe storms are still on track.

Thunderstorms overnight and Monday morning

As of 2 a.m., tornado warnings piled up along Minnesota-South Dakota as strong storms began rolling in. Thunderstorms tracked ENE over the next 6 hours. FOX 9 storm chaser Tim Purington reported the roof of his hotel in Sioux Falls, South Dakota, was torn off by high winds.

At 3:30 a.m., a Renville County emergency official reported that a severe thunderstorm pushed a squall onto Highway 212 near Sacred Heart, blocking the roadway.

Between 4 a.m. and 5 a.m., wind gusts of 65 mph were reported from Sauk Center to St. Cloud. These storms then pushed towards Little Falls and Mora, with wind gusts of up to 70 mph as the storm moved northeast through Carlton, Douglas, Pine and St. Louis counties.

Memorial Day camping cut short

Just outside of Hudson, Wis., at Willow River State Park, many campers were packing early to avoid any hazards.

“It’s all metal and canvas, so you don’t know what’s going to fall and break your stuff or what’s really safe,” said one camper. “I don’t even know where the shelters are or if there are any in this area.”

While the possibility of severe storms on Sunday night diminished late in the day, the chance of tornadoes on Monday sent plenty of packing.

“It’s a bit of a dealbreaker,” said another camper. “A tornado is a little worse than just rain.”
