When tornadoes hit here

By month

July is the peak month, with 51 of 136 tornadoes.

By time of day

Most often around 4:00 PM. Times as recorded by NOAA, mostly Central Standard Time.

By year, 1950 to 2025

The line is the five-year average. Tornadoes before about 1953 were under-reported, and better radar since the 1990s finds more weak ones.

By rating

EF0

EF1

EF2

Ratings before February 2007 use the original F scale; the numbers line up with today's EF scale. Unknown means NOAA could not assign a rating.
