I have family in southern/central Ohio and, while they've always been a risk, there has been a marked uptick in the occurrence of tornadoes. Xenia, OH very famously has been hit multiple times by serious tornadoes. Where my parents are, where I did most of my growing up, in southeastern Ohio, is a little safer because of the Appalachian foothills, but I fondly remember the tornado sirens blaring every Wednesday at noon during the spring, summer, and fall.
A friend of mine from high school, who is a meteorologist and storm chaser today, was telling me the last time that we spoke that tornado alley is potentially / actually shifting eastward over time. I haven't tried to verify what he was saying, because I trust him given his career choices, but it does seem to bear out from the anecdata that I have available.
