likeliehood of me encountering a tornado

[Anubis]

I live in Kentucky, about 15 miles away from the Ohio river and 10 or so miles away from Louisville. Given this information, could anybody tell me the likliehood of my area getting hit by a tornado F2 or above?
Last month this area got hit by a pretty bad t-storm, and tornadoes were produced, but none touched down.

In the highest risk areas, a tornado of significant strength would be expected to occur once every 2000 years, at each point in the area shown. For the high-risk areas, the interval would be once every 5000 years.

Louisville appears to be near the boundary between “highest” and “high” risk areas.
