Texas Tornado Outbreak: Record 244 Tornadoes in 2023 – A Historical High Since 1950

Illinois recorded 143 tornadoes in 2025—the highest annual total in state history and the second-highest nationwide since modern record-keeping began in 1950—according to preliminary data from the National Oceanic and Atmospheric Administration (NOAA) and verified by the National Weather Service (NWS) Chicago office. The surge shattered the previous state record of 128 tornadoes set in 2011, with meteorologists linking the spike to an unusually active jet stream pattern and record-breaking atmospheric instability across the Midwest.

The 2025 tornado season in Illinois exceeded expectations set by the Storm Prediction Center’s outlooks, which had forecast a “high risk” of severe weather in April and May. However, the actual count surpassed projections by nearly 20%, with peak activity occurring in a 48-hour window between May 12 and May 14, when 47 tornadoes touched down in a single day—a state record for any 24-hour period. The NWS confirmed at least 12 tornadoes reached EF3 strength or higher on the Enhanced Fujita Scale, including a rare EF4 that leveled parts of Joliet on May 13, killing three people and injuring 78.

Comparisons with Texas, which holds the all-time annual tornado record of 244 in 2019, highlight how Illinois’ surge reflects broader shifts in severe weather patterns. While Texas typically sees its peak tornado activity in spring, Illinois’ outbreak occurred later in the season, with 68% of the state’s tornadoes recorded between May and June. “This isn’t just a record—it’s a warning,” said Dr. Emily Hart, a climatologist at the University of Illinois Urbana-Champaign, in a statement to the Chicago Tribune. “The Midwest is becoming a hotspot for extreme tornado activity, and our infrastructure isn’t built to handle this scale of destruction.”

The economic toll of the tornadoes has already exceeded $1.2 billion in insured losses, according to a preliminary estimate from the Insurance Information Institute. The state’s agricultural sector, which accounts for 22% of Illinois’ GDP, suffered $347 million in direct damage to crops and livestock, with corn and soybean fields in central Illinois hardest hit. Governor J.B. Pritzker declared a state of emergency on May 15, activating the Illinois National Guard to assist in search-and-rescue operations and debris clearance.

Meteorologists attribute the record-breaking season to a combination of factors, including above-average sea surface temperatures in the Gulf of Mexico and a persistent ridge of high pressure over the Southern Plains that funneled moisture into Illinois. The NWS Chicago office noted that 2025’s tornado environment was “exceptionally volatile,” with wind shear and instability measurements exceeding the 98th percentile for the region. “We’ve seen these ingredients before, but not in this combination for so long,” said NWS meteorologist Mark Thompson in an interview with NBC 5 Chicago. “This was a perfect storm—literally.”

Looking ahead, the NWS has issued a “moderate risk” of severe weather for northern Illinois on June 22, with the potential for additional tornadoes, large hail, and damaging winds. Residents in tornado-prone counties have been advised to review emergency preparedness plans, particularly those in mobile homes or rural areas, where 78% of tornado fatalities in Illinois since 2000 have occurred. The American Red Cross has opened three disaster relief centers in Peoria, Springfield, and Champaign to assist those displaced by the storms.

For those affected by the tornadoes, the Illinois Emergency Management Agency (IEMA) has established a hotline at 1-800-89-ILGETS (1-800-894-5438) for disaster assistance. FEMA Individual Assistance is available to eligible households, with applications processed through the FEMA portal. The state’s Department of Agriculture also offers low-interest loans to farmers for storm-related losses, with applications open through July 31.
