2021 Tornado Data

[Hoosier]

I did IL, IN, KY, MI, OH, WI... but if anyone wants to add data from fringe states like IA or MO, feel free.

There were 221 tornadoes.  This includes 1 tornado that crossed from Illinois into Indiana, which is counted as a tornado for each state but is only counted once in the cumulative 6 state monthly/intensity totals at the bottom.

On a very local note, there were tornadoes on 3 different calendar dates in my county this year.  The only other time that has been recorded was in 1976.  I actually think that is more impressive than having 3 tornadoes in a county on the same day, because a cyclic supercell or a QLCS with embedded areas of rotation can produce a few tornadoes pretty quickly.  There are a relatively limited number of days that are favorable for tornadoes in a given place in a given year, so to pull it off on 3 separate days with varying conditions/parameters is noteworthy.
