Midwest tornado activity eastward shift

Overview

Tornado activity in the United States is shifting eastward from the traditional ‘Tornado Alley’ into more densely populated regions of the Midwest. This movement into states such as Illinois, Indiana, and Wisconsin is increasing insurance risk and economic losses due to higher population exposure, even if total national tornado counts have not necessarily risen.

Illinois has seen a historic surge in activity, recording over 200 confirmed tornadoes through July 2026. This figure exceeds the state’s previous record of 142 set in 2024 and is more than triple its typical annual average of 66. Wisconsin has also reported a significant spike in activity, while Indiana has seen record-high numbers.

Experts attribute this eastward expansion to a warming climate that facilitates the transport of warm, humid air further north and east. Tory Farney, vice president of Verisk Weather Solutions, noted that the primary concern for insurers is the higher population density in these expanding storm zones.
