Rare Tornado Tears Across Michigan’s Upper Peninsula—What We Know

“We’ve lived here for 40 years and never seen anything like it,” says Mark Jutila, a meteorologist with the National Weather Service office in Marquette, Michigan. “This wasn’t just a thunderstorm. This was a beast.”

On Tuesday afternoon, a powerful tornadic storm carved a path of destruction across Michigan’s Upper Peninsula, a region more accustomed to lake-effect snow than violent springtime twisters. The storm, which touched down near the small town of Chatham at approximately 3:45 PM EDT, tore through Alger County and continued northeast, leaving snapped trees, damaged homes, and a community in shock. While the U.P. sees its share of severe weather, a confirmed tornado in this part of the country is rare — and this one was anything but ordinary.

An Unlikely Setting for a Twister

The Upper Peninsula isn’t exactly Tornado Alley. In fact, since 1950, only about 20 tornadoes have been recorded in Michigan’s northernmost region. Most are weak, short-lived EF0 or EF1 events. But Tuesday’s storm was different. Preliminary reports from the National Weather Service suggest the tornado reached at least EF2 intensity, with winds estimated between 111 and 135 mph.

“The atmospheric setup was reminiscent of what we’d see in Kansas or Nebraska,” explains Dr. Sarah Collins, a severe weather researcher at the University of Michigan. “A strong low-pressure system, abundant moisture from Lake Superior, and extreme wind shear all came together in a dangerous cocktail.”

That mix created a supercell thunderstorm that dropped a tornado near Chatham around 3:45 PM. The twister stayed on the ground for roughly 12 miles, according to preliminary surveys, before lifting near the community of Trenary. Along its path, it uprooted hundreds of trees, ripped roofs off several homes, and flipped a camper trailer. Miraculously, no fatalities have been reported, though two people sustained minor injuries.

For comparison, this same week, the Eastern US Braces for Dangerous Heatwave — a stark reminder that extreme weather is striking in unexpected places.

Why the U.P.? Blame the Jet Stream

So what the heck is a tornado doing in the U.P.? The answer lies in the jet stream, which has been doing cartwheels across North America this spring. A deep trough of low pressure over the Great Lakes pulled warm, humid air northward from the Gulf of Mexico — unusual for May in northern Michigan. Meanwhile, a strong upper-level jet provided the wind shear needed to spin up storms.

“It’s the same dynamics that produce tornadoes in the Plains, just shifted north,” says Collins. “Climate change may be playing a role in expanding the geographic range of severe thunderstorms.”

That’s a worrying thought for residents who’ve never had to think about tornado safety. In Chatham, a town of just 200 people, many homes lack basements — standard for a region where tornadoes are considered a freak occurrence. “We just huddled in the bathroom,” says local resident Amy LaRue. “We don’t have a storm shelter. Nobody does.”

Damage Assessment and Recovery

As of Wednesday morning, damage assessment teams from the National Weather Service had surveyed about 80% of the tornado’s path. The preliminary rating of EF2 could be upgraded if they find evidence of more severe structural damage. “We’re seeing some homes with roofs completely torn off and exterior walls collapsed,” says NWS Marquette meteorologist Jutila. “That’s consistent with EF2 or even low-end EF3 damage.”

The storm also produced damaging straight-line winds ahead of the tornado, with gusts measured at 80 mph in Munising. About 3,500 customers lost power across Alger and Delta counties, according to the local utility, Alger Delta Cooperative. Crews were working through the night to restore electricity, but some rural areas may remain without power into the weekend.

Governor Gretchen Whitmer declared a state of emergency for Alger County late Tuesday, freeing up state resources for cleanup and recovery. “This is a reminder that severe weather can strike anywhere, anytime,” Whitmer said in a statement. “We’re grateful no lives were lost, and we will support these communities every step of the way.”

The American Red Cross has set up a shelter at the Chatham Community Center, offering food, water, and emotional support for displaced residents. For many, the shock is still setting in. “You hear about tornadoes in Oklahoma or Kansas,” says LaRue, her voice shaky. “You never think it’s gonna be your house.”

What This Means for You

Look, if you live in the Upper Peninsula — or anywhere outside the traditional Tornado Alley — this storm should be a wake-up call. Tornadoes are becoming more common in regions where they were once rare. A 2022 study in the journal Climate and Atmospheric Science found that the frequency of tornadoes in the Midwest and Southeast has increased by about 20% over the past 40 years, while the number in the Plains has actually declined slightly.

“The ‘Tornado Alley’ concept is becoming outdated,” says Dr. Collins. “We’re seeing tornadoes in Michigan, Ohio, Pennsylvania — even New Jersey. Everyone needs a plan.”

That means having multiple ways to receive warnings: NOAA weather radios, smartphone alerts, and local news. Know where to go — an interior room on the lowest floor, away from windows. And if you don’t have a basement, consider investing in a storm shelter or safe room. It’s not expensive compared to the alternative.

For those in the U.P., the immediate priority is recovery. But for the rest of us, this tornado is a sign of things to come. As the climate warms, the atmosphere holds more moisture and energy — fuel for extreme storms. The question isn’t whether we’ll see more tornadoes in unexpected places. It’s whether we’ll be ready when they arrive.

Looking ahead, the National Weather Service expects a return to more typical weather for the U.P. this weekend, with highs in the 50s and a chance of rain. But for communities like Chatham and Trenary, the scars of Tuesday’s storm will take much longer to heal. And the memory — the roar, the shaking, the sudden silence — will last a lifetime.
