1956 -- Three significant tornadoes moved across northern Indiana. One hit near Silver Lake and did damage at Yellow Creek Lake in Kosciusko County. Another just missed Wawaka, where it picked up a barn and dropped it on Route 6. The third twister touched down on the north side of Topeka and lifted west of Lagrange.
1974 -- At 2:07pm a tornado touched down near Morris, Illinois. Over the next eighteen hours another 147 twisters would touch down over the eastern third of the United States, comprising the largest known tornado outbreak, dubbed the Super Outbreak. 315 people were killed, 6142 injured, over 27,500 families had some sort of loss, and damage was estimated at $600 million. Twenty tornadoes killed 49 people in Indiana between 2:20pm and 8pm. The fortieth tornado of the outbreak was an F5 that hit Depauw, Indiana at 2:43pm. The longest tornado path of the day was tornado number 13, which struck Monticello, Indiana at 5:15pm along its 97-mile long path (recent research suggests that this was actually three separate tornadoes along the same path).
1982 -- A tornado hit Adams City, Indiana, at 3:10am.
