Crowell, Texasat around 3:05 P.M. About 35 minutes later, the tornado ripped through Vernon and killed 11 people. Then the tornado killed three people in Lawton, Oklahoma. The second supercell spawned a tornado that moved convert|64|mi|km|0.
The third supercell was the one that formed the tornado that moved through

The storm formed in
Archer County, Texasand moved northeast and damaged a few rural homes and high voltage towers. The tornado then moved into Wichita County, Texasand severely damaged Memorial Stadium and McNiel Junior High School. The tornado destroyed an apartment complex across the street. The tornado also took its first lives at the complex. The tornado later destroyed a restaurant, part of Sikes Senter, the major mall in the town, and another apartment complex where the tornado took more lives.
A number of people tried to flee as the tornado moved along US Highways 281 and 287. More people were killed in their cars. The tornado then moved into Clay County and changed its appearance. There were five satellite tornadoes spinning around the parent tornado. It did more damage south of Dean and Byers, TX, but no more fatalities.
At the end of the outbreak, 54 people lost their lives in Texas, three were killed in Oklahoma and one was killed in
Indiana. The Wichita Falls tornado alone killed 42 people, a death toll which was unmatched until the 1999 Oklahoma tornado outbreakin 1999. The tornado caused $400 million in damage which, also up until the Oklahoma tornado outbreak, made it the costliest tornado in U.S. history. An convert|8|mi|km|0 swath of the city had almost unheard of devastation. Dr. Ted Fujita, who was working at the University of Chicago, said the tornado caused as much as F4 damage on the east and south sides of the city. What was unique about this tornado was that it caused a wide swath of F4 damage. Ordinary tornadoes only have a small path of their most intense damage.
