On June 11, the central United States experienced a new dangerous wave of extreme weather. This was not a local episode, but a regional outbreak of severe storms with tornadoes that affected several states at once: Illinois, Indiana, Iowa, Nebraska, and Missouri.
Northern and central Illinois, as well as northwestern Indiana, suffered the most from the tornadoes.
According to the National Weather Service, at least 42 tornadoes were confirmed.
One of the hardest-hit areas was the city of Streator, Illinois. There, an EF-3 tornado damaged at least 79 homes. 44 residential buildings sustained major damage or were completely destroyed.
Seven people were injured. Four of them were taken to the hospital by emergency services, while three others sought medical help on their own.
After the tornado passed through, Streator authorities issued a ban on open burning of debris in the affected areas. Residents were warned about the danger of damaged structures, possible gas leaks, and downed power lines.
Another powerful EF-3 tornado was confirmed near Washburn in central Illinois. The tornado reached peak intensity with winds of 155 miles per hour in rural Marshall County. It raged for 19 minutes and left a damage path 11.23 miles long, with a maximum width of 930 yards.
The damage was significant: roofs were torn from homes, and the walls of a log home were destroyed. Trees and agricultural crops were also badly damaged: leaves were stripped from corn plants, and some of the plants were uprooted.
Severe damage was also recorded in Indiana. In Merrillville, a tornado was rated EF-2. The damage affected residential and public buildings, and part of the roof was torn off one school.
An even stronger EF-3 tornado was confirmed near Kouts, in Porter and LaPorte Counties.
The damage path across Porter and LaPorte Counties was especially visible in rural infrastructure. According to local officials, the tornado tore apart grain bins, collapsed irrigation systems, and scattered debris for miles.
In northern Indiana, an EF-2 tornado was also confirmed near Bristol in Elkhart County. Several homes had their roofs torn off or damaged there. One person was injured.
Miraculously, the tornadoes caused no fatalities, but the powerful storms still led to tragedy.
In a park in Iowa, strong winds snapped a tree, which fell on a man. He died at the scene.
It is worth noting that tornado activity in the Midwest in 2026 is showing a highly unusual pattern. In Illinois, where an average of about 54 tornadoes are recorded each year, there had already been a combined total of 145 tornado reports and confirmed tornadoes by June 14. The state became the national leader by this measure, surpassing even traditionally tornado-prone Oklahoma, Texas, Kansas, and Alabama.
This was preceded by a persistent weather pattern: a sharp southward dip in the jet stream shifted toward the Midwest and interacted with warm, humid air. These are classic conditions for the development of severe thunderstorms, supercells, and tornadoes.
This situation shows that the familiar geography and seasonality of tornadoes are changing significantly. That is why science and emergency services need to study new climate patterns more deeply, so that people and cities can better prepare for growing weather risks.
