Illinois Ranks Second Nationwide for Tornadoes in 2025 as U.S. Records Exceptionally Active Severe Weather Year
ILLINOIS — As 2025 comes to a close, new preliminary data from the Storm Prediction Center shows Illinois finishing the year with 141 confirmed tornadoes, ranking second-highest in the nation, behind only Texas. The total places Illinois far above its long-term annual average and marks one of the most active tornado years ever recorded for the state.
Nationally, the United States recorded 1,551 tornadoes between January 1 and December 30, according to preliminary counts, underscoring how unusually intense the 2025 severe weather season became across large portions of the country.
Illinois Far Exceeds Its Historical Tornado Average
Illinois typically averages around 50 tornadoes per year, but the 2025 total nearly tripled that norm, continuing a trend of elevated tornado activity seen in recent years. For comparison, Illinois logged 142 tornadoes in 2024 and 121 tornadoes in 2023, making the past three years some of the most tornado-active on record for the state.
The concentration of tornadoes across Illinois reflects repeated rounds of severe thunderstorms during spring, summer, and early fall, often fueled by strong jet stream patterns and frequent clashes between warm, moist air from the Gulf and colder air masses from the north.
How Illinois Compared to Other States in 2025
Texas once again led the nation with 162 tornadoes, narrowly edging Illinois for the top spot. Several Midwestern and Southern states also posted high totals, reinforcing the Midwest and lower Mississippi Valley as major focal points for severe weather this year.
Other notable totals included:
- Missouri: 120 tornadoes
- Alabama: 111 tornadoes
- Iowa: 56 tornadoes
- Wisconsin: 38 tornadoes
- Michigan: 31 tornadoes
Meanwhile, parts of the Northeast and West Coast recorded relatively low tornado counts, highlighting how geographically concentrated the most extreme activity remained.
What Drove the Extreme Tornado Numbers in Illinois
Meteorologists point to persistent storm-favorable patterns throughout 2025, including frequent warm fronts, strong upper-level disturbances, and repeated high-instability setups across the Midwest. Illinois repeatedly found itself in the path of long-lived storm systems capable of producing multiple tornadoes during single outbreaks.
Several multi-day severe weather episodes contributed heavily to the final count, with some outbreaks spawning dozens of tornadoes across the state in just a few hours.
Why the 2025 Tornado Season Matters Going Forward
The continued run of high tornado totals raises concerns about changing severe weather behavior, preparedness, and infrastructure resilience across Illinois. Emergency managers stress that residents should remain vigilant even outside the traditional peak tornado months, as the season continues to expand earlier in spring and later into fall.
While final, adjusted tornado counts will be released after full storm surveys are completed, officials say the overall picture is unlikely to change: 2025 was an exceptionally active and dangerous tornado year for Illinois and much of the United States.
Residents are encouraged to review severe weather safety plans, ensure weather alerts are enabled, and stay informed as meteorologists analyze what this active year may signal for future seasons.
