1975 Omaha tornado outbreak
Three people were killed and 133 reported injured. One of the fatalities was thrown by the tornado from her home to a backyard four or five houses away. Debris was found miles away. Over 4,000 buildings were damaged and 287 were destroyed. In terms of damage, it was the costliest tornado in American history to that date, with damages costing at least $250 million to $300 million (around $1.7 billion in 2015 dollars), and insurance costs estimated at up to $1.1 billion (in 1975). It was the third-costliest tornado, behind the Oklahoma City-area F5 tornado on May 3, 1999, and the Wichita Falls, Texas, tornadoes on April 10, 1979, until the Joplin, Missouri EF5 tornado on May 22, 2011. It is now currently the seventh-costliest tornado on record.
1948 Tinker Air Force Base tornadoes
Although storms were relatively benign up to the point where they reached Tinker, a supercell formed just west of the base, and at around 6 pm a tornado touched down on the base for the second time in six days. This second tornado caused $6 million in damage, or $ million in dollars. However, due to precautions enacted because of the tornado forecast, no injuries were reported, and damage totals could have been much higher.
