Courtney Scott was driving her 8-year-old son home from school in St. Louis last spring when trees began to fall around her car. Not moving. Falling to the left, the right, and straight ahead. She quickly turned around and kept driving. Later, the authorities said it was a tornado that cut through the city a mile wide. Scott thinks that turn kept them alive.
In Missouri, even twenty years ago, this story would not have seemed likely. In Kansas, there were tornadoes. In Oklahoma. There wasn’t much to hit out on the flat, windswept plains. That’s what people thought. That’s how the maps looked. However, the maps are shifting, and people in Missouri and the Midwest as a whole are starting to notice this in strong ways.
In 2024, Missouri had 93 tornadoes. In 2025, it had 104. So far in 2026, it has already had 81. The yearly average for the state is 52. That number is not a fluke. Researchers have been keeping an eye on these changes for years: tornadoes are slowly but surely moving eastward, away from the traditional Great Plains corridor and into areas with more people.
Victor Gensini, a professor at Northern Illinois University, published research on this change in 2018. Since then, he has seen the trend continue and even speed up. “Tornadoes have been happening with less frequency in the Great Plains over the last 40 years,” he stated, “and they’ve been having greater frequency in places like Illinois and Indiana and Tennessee.” Illinois had more than three times its usual number of tornadoes each year by the middle of 2026, with 178 already having been recorded. Indiana beat its own record from the past. Things are also very different in Iowa. It gets harder to say that any of this is strange.
Meteorologists and climatologists say that the old mental map of the risk of tornadoes in the United States needs to be updated. The name “Tornado Alley” was made up by two Air Force meteorologists who were studying bad weather in Texas and Oklahoma in 1952. It stayed around for 70 years. But it was based on data from a very different time, and the weather since then hasn’t really stuck to the original definition.
Researchers think that moisture is part of the reason for the shift. The Southwest has been in a drought for a long time, which has cut down on the warm, humid air that usually fuels storms in the Great Plains. At the same time, the Gulf of Mexico has warmed up, which has sent more water north into the river valleys of the Mississippi and Tennessee. Combining those things is basically making tornadoes more likely in places that haven’t had them before. Scientists are cautious about drawing straight lines, so it’s still not clear how much of this is directly linked to climate change. However, the pattern is strong enough that it’s hard to say it’s just a coincidence.
Because of its location, Missouri is in a bad spot. Zack Leasor, a climatologist for the state, says it is “on the path” of the shifting alley, stuck between the traditional Great Plains corridor and the new Southeast hotspot, which runs from Arkansas to Tennessee and is sometimes called Dixie Alley. It turns out that standing between two active zones is not safe.
Beyond the raw numbers, what really worries me about this is how densely the people are living. The first version of Tornado Alley mostly went through farmland. In 1975, a tornado in western Kansas could destroy a wheat field and hurt a grain elevator. If a tornado hits near St. Louis, outside of Indianapolis, or in a Memphis suburb, it can damage homes, schools, hospitals, and highways. The effects are not only different in level, but also in type.
There isn’t a simple answer here. Scientists are still trying to figure out what’s causing the trend to the east, and meteorologists aren’t sure where it will go next. And they’ll say that the proof has been growing for years and that 2026 is just another part of it. This is probably less important to the people who live in its path, like Courtney Scott, who have to make quick decisions on wet streets, than the academic debate. They need to know if their community is ready for what looks like it’s coming.
