April 11th, 1965.
Its a beautiful sunny afternoon across northern Indiana and residents all across the state are beginning to venture outdoors to enjoy the pleasant spring weather after a long and brutal winter. None of them could have imagined that in just a few short hours they would be at the center of one of the worst tornado outbreaks in American history.
On April 11th, 1965, a catastrophic tornado outbreak would devastate the midwestern states of Iowa, Wisconsin, Illinois, Indiana, Michigan, and Ohio, producing over 50 tornadoes and claiming the lives of 266 people, causing apocalyptic levels of destruction matched only by the 1925 Tri-state tornado and the 1974 and 2011 Super Outbreaks. In this video we will discuss the fascinating meteorology that caused this devastating and often overlooked tornado outbreak, the people it impacted, and the scientific breakthroughs that happened in its aftermath. This is the true story of the 1965 Palm Sunday Tornadoes: The Forgotten Super Outbreak.
