NOAA's Storm Prediction Center has updated the tornado database and all tornadoes from 1950 through 2016 are included.
Below are maps of all tornadoes, without comments I plotted from the data for the Cincinnati area.
All maps plotted using the free, open source MapWindows GIS program and U.S. Taxpayer data from NOAA's Storm Prediction Center.
