June 16, 2014:

One of the 2010s' most unique tornadic events saw a cyclic cell spawn four EF4s in northeast Nebraska. For much of the storm's life, two violent wedges were on the ground at the same time. Pilger took a devastating direct hit. Two people were killed.

Illinois remains the top state in the country for tornadoes so far this year and it’s not even close with Mississippi coming in at a distant second. #ilwx

In Illinois:
Tornado average per year is 54.
Tornadoes in 2025: 146
Tornadoes in 2024: 142
Tornadoes in 2023: 136

This is the correct and updated list.
