The storms continued to push northeast, and a Particularly Dangerous Situation was issued for Liberty Center as the tornado stayed on the ground. It was responsible for power line damage and a propane leak in Okolona, and a semi truck was blown over on U.S. 24 between Liberty Center and Napoleon.

It was not immediately known if the Ohio tornadoes were responsible for any injuries or deaths.
