Illinois sets record with 220 tornadoes so far in 2026, most of any state this year

CHICAGO — Illinois has recorded 220 tornadoes so far this year, a preliminary count that marks the most tornadoes reported by any state in 2026 and the highest single-state total since Texas set an all-time national record of 244 in 2015.
The tally, current through July 29, comes amid an unusually active spring and summer of severe weather across the Midwest, which has seen repeated rounds of destructive thunderstorms and tornado outbreaks in recent months.
AccuWeather Meteorologist Peyton Simmers said the concentration of tornado activity in Illinois this year stems from atmospheric conditions that have kept storm systems farther north than usual, sparing states more traditionally associated with tornado outbreaks.
“The dynamics this year have favored Illinois, with storms staying to the north of Texas and Oklahoma,” Simmers said. “The dynamics are the energy needed to produce thunderstorms in the upper part of the atmosphere. The stronger the dynamics, the more energy that storms can tap into [to] produce severe weather including tornadoes.”
Illinois’ total this year far exceeds its historical average and surpasses the state’s previous single-year record of 142 tornadoes, set in 2024, according to earlier data from the National Weather Service and the Storm Prediction Center. Meteorologists have said the increase reflects both a favorable storm pattern and improved detection technology, which has made it easier to confirm smaller, shorter-lived tornadoes that might once have gone unrecorded.
The severe weather has not been confined to Illinois. Indiana has already set a new state record for tornadoes this year, while Missouri and Wisconsin remain on pace to potentially challenge their all-time yearly highs, according to the report.
Nationally, Texas continues to hold the record for the most tornadoes reported by a single state in one year, with 244 in 2015. Illinois’ 2026 total now ranks as the second-highest single-state count on record, though final numbers for the year could still change as the Storm Prediction Center reviews and confirms additional reports.
