OHIO — As the region approaches its traditional spring severe weather uptick, newly highlighted 30-year data is putting tornado risk across the Miami Valley and neighboring Indiana into clearer perspective. The latest probability map, based on Storm Prediction Center data from 1994–2024, shows that much of western Ohio faces a 70–80% annual chance of a tornado occurring within 25 miles of a given location.
This does not mean every town sees a tornado every year — but statistically, somewhere within a 25-mile radius, one is likely to occur during a calendar year.
