March tornado outbreaks tear from Oklahoma to Michigan, exposing early-season risks

UNION CITY, Mich. — The house by Union Lake is gone, save for a fireplace and a slab of flooring. A 500-gallon propane tank rests where it does not belong, hurled across the yard. In the school gym a mile away, cots line the basketball court, where families in winter coats shuffle between folding tables stacked with donated clothes and cleaning supplies.

The scene could be mistaken for the aftermath of a mid-May tornado on the Great Plains. Instead, it is southern Michigan in the first week of March — a time when residents are more accustomed to wet snow and raw winds than 150 mph gusts.

In less than a week this month, two powerful storm systems produced more than 120 tornadoes from Texas and Oklahoma to the Great Lakes and the Mid-Atlantic. At least 11 people were killed and dozens injured between March 5 and March 12, as twisters struck after dark in rural Oklahoma, ripped through lakeside homes in Michigan and carved a deadly path across cornfields and small towns in Illinois and Indiana.

The back-to-back outbreaks hit earlier in the year and farther north than many people expect, and they exposed familiar weak spots: nighttime storms, vulnerable housing and confusion about what color-coded risk maps really mean.

“We were under a Marginal Risk that day, but the storm environment over far southern Lower Michigan was much more volatile than it looked on the broad outlook,” the National Weather Service office in northern Indiana wrote in an event summary of the March 6 tornadoes. “Significant and violent tornado parameters were maximized right as the supercell crossed the state line.”

A deadly start in Oklahoma

The first outbreak began March 5 as a deep low-pressure system swept out of the Rockies and across the Plains. In western Oklahoma that evening, a large wedge tornado touched down in Major County and crossed U.S. Highway 60 west of Fairview.

Authorities said 47-year-old Jodie Owens and her 13-year-old daughter, Lexi, were killed when the tornado struck their vehicle on the highway after dark. Survey teams later rated the Fairview storm an EF2, with estimated winds of 120 to 130 mph.

The next night, as darkness fell again, a stronger tornado formed near Beggs, a small community in Okmulgee County south of Tulsa. The National Weather Service office in Tulsa said the storm reached EF3 intensity, with winds over 135 mph and a path up to about half a mile wide. It destroyed or heavily damaged homes, snapped large trees and cut power to thousands.

Okmulgee County officials reported that two people were killed in a house and two others were injured. Residents in Beggs and nearby towns later raised questions about whether outdoor warning sirens sounded in time, and local officials said they were reviewing system performance and communication procedures.

Gov. Kevin Stitt declared a state of emergency in multiple Oklahoma counties after the March 5–6 storms, allowing the state to mobilize resources more quickly and prepare requests for federal assistance.

A “Marginal Risk” day turns historic in Michigan

On March 6, forecasters at the Storm Prediction Center in Norman, Oklahoma, were focused on the southern Plains. The corridor flagged for the greatest severe weather risk stretched roughly from Texas and Oklahoma into parts of the lower Mississippi Valley. Farther north, southwest Michigan sat under the lowest of the center’s five threat categories: a Marginal Risk, shaded green on national maps that many viewers see on television and social media.

That afternoon, conditions over the Michigan-Indiana border quietly sharpened. A single, powerful supercell thunderstorm crossed into Cass County and began producing tornadoes in rapid succession.

The first, an EF1, touched down near Edwardsburg and Cassopolis. It damaged homes and uprooted trees. In the chaos, a sixth-grade boy, identified by family and school officials as 12-year-old Silas Anderson, was fatally injured. He was later pronounced dead at a hospital.

Minutes later, the same storm intensified over Three Rivers in St. Joseph County. The Weather Service rated that tornado mainly EF2, saying it tore parts of the roof off a Menards home improvement store, damaged a U-Haul facility and inflicted structural damage on Three Rivers Health hospital. Several people were hurt, but no deaths were directly attributed to that track.

The most violent phase came as the supercell reached the Union City area along Union Lake in Branch County. There, surveyors found what they called high-end EF3 damage: an anchored home swept from its foundation, with only the fireplace and a subfloor remaining; severe debarking of trees; ground scouring; and the displaced propane tank.

Winds were estimated at 150 mph. Three people were killed, all in mobile homes near the lake, and a dozen others were injured.

Meteorologists in Michigan said the Union City tornado was the earliest EF3-strength storm on record in the state and the strongest so early in the season. The Weather Service noted that Michigan had not seen an EF3 or stronger tornado in March in modern records.

Gov. Gretchen Whitmer declared a state of emergency for Branch, Cass and St. Joseph counties after touring damage. “We will do everything we can to help these communities recover,” she said in a statement, adding that the declaration would “unlock critical state resources and support.”

In Union City, the local high school quickly became the center of that effort. Administrators opened the building around the clock as a shelter and relief hub, offering hot meals, showers and space for donations.

“It’s become a round-the-clock resource center for anyone affected by the EF3,” a local television reporter said in a broadcast from the gym, as volunteers moved pallets of bottled water and pet food.

Five days later, a “Moderate Risk” bull’s-eye

The atmosphere reloaded almost immediately. Early on March 10, the Storm Prediction Center issued a Day 1 outlook highlighting an Enhanced Risk of severe thunderstorms from northern Missouri into northern Illinois and northwest Indiana and across parts of Texas. In technical language, forecasters warned that “all severe hazards are possible, including the risk for a few strong tornadoes and very large hail.”

By early afternoon, new model data and satellite trends prompted an upgrade. In a 2:50 p.m. update, the center carved out a tornado-driven Moderate Risk — the second-highest category — centered on northern and central Illinois into northwest Indiana.

“Scattered to numerous severe thunderstorms are expected,” the outlook said, “including the risk for multiple strong to intense tornadoes, damaging winds, and very large hail.”

One of those storms developed near Kankakee, Illinois, south of Chicago, and tracked northeast. It soon produced a long-track tornado that began near the village of Aroma Park, cut across rural Kankakee County, then crossed the state line into Newton County, Indiana, striking the community of Lake Village.

Survey teams rated the tornado EF3, with peak winds near 160 mph. Officials in Illinois and Indiana said three people were killed along the path — one near Aroma Park and two in Lake Village — and at least 11 others were injured. Dozens of homes and farm buildings were damaged or destroyed.

The same supercell produced enormous hail. The Weather Service documented a 6.1-inch hailstone near Kankakee, which, if formally confirmed, would break the Illinois state record for largest hailstone, previously 4.75 inches.

As the storm moved east, it spawned more tornadoes, including an EF2 near Knox, Indiana, that prompted a rare “tornado emergency” warning and an EF1 near Wheatfield that injured several people.

In the following 48 hours, the system pushed into the Ohio Valley, Mid-Atlantic and Southeast, triggering additional tornado warnings in parts of Ohio, Maryland, Virginia and southern Georgia, some of them after dark.

An earlier, broader season

Meteorologists say tornadoes in March are not unusual in the United States, particularly across the Deep South and southern Plains. What stands out about this year’s outbreaks is where and how quickly high-end storms developed.

On March 10, the primary Moderate Risk area over Illinois and Indiana sat north of the typical March 10 severe-weather maximum, which historically favors areas closer to the Gulf Coast. Four days earlier, Michigan had already been hit by what one local forecaster described as “the earliest EF-3 tornado ever recorded in the state.”

By midmonth, weather enthusiasts and researchers were tallying roughly 60 tornadoes in March and 11 fatalities, a high toll this early in the year.

Scientists caution against attributing any single extreme-weather episode directly to climate change. Tornado counts vary widely from year to year, and the storms themselves are small enough that long-term trends are hard to tease out. But several studies have suggested that the greatest frequency of severe storm days has been shifting gradually eastward from the traditional Great Plains “Tornado Alley” toward the Mississippi Valley, the Midwest and parts of the Great Lakes and Mid-South.

A warming atmosphere can also hold more moisture and may influence the jet stream and storm tracks, potentially affecting when and where the overlapping ingredients for tornadoes occur.

“We’re seeing more of these early-season outbreaks in places that historically expected their worst severe weather later or not at all,” said one atmospheric scientist who studies severe storms. “That doesn’t mean every year will look like this, but it does mean communities need to think carefully about preparedness.”

Warnings, housing and what comes next

The March storms also underscored familiar vulnerabilities.

Nighttime tornadoes, like the ones in Fairview and Beggs, have long been associated with higher fatality rates. People are asleep, storms are harder to see and many residents continue to rely on outdoor sirens rather than phone alerts or weather radios indoors.

In Michigan, the worst destruction occurred in manufactured housing. All three victims in Union City died in mobile homes, even as some well-anchored nearby homes suffered severe but survivable damage.

Weather Service survey notes from similar events have repeatedly pointed out that in areas dominated by weaker construction, it can be impossible to distinguish EF3-level damage from what might have occurred in stronger winds, simply because the buildings fail completely at lower thresholds. That blending of signal and construction quality has consequences both for official ratings and for safety.

Local and state officials in Oklahoma and Michigan have already begun reviewing siren systems, alerting protocols and shelter options. In the Illinois-Indiana corridor, rural officials are taking stock of damage while farmers and homeowners weigh how and whether to rebuild structures to higher wind standards.

For now, families in Union City, Beggs, Kankakee County and a dozen other communities are focused on more immediate tasks: hauling debris, filing insurance claims, figuring out school schedules and where to sleep.

The storms that tore through their towns are part of a long American history of springtime tornadoes. But as outbreaks come earlier, strike farther north and roar through communities after dark, the March 2026 season suggests that the map of who is at risk — and when — is changing faster than many people’s expectations.
