1979 Red River Valley tornado outbreak

A destructive and deadly tornado outbreak impacted the Red River Valley on April 10, 1979. Several strong to violent tornadoes touched down throughout the region that day. One F4 tornado impacted Vernon, Texas. The most notable tornado was another F4 tornado that destroyed most of the southern part of Wichita Falls, Texas, and is commonly referred to as "Terrible Tuesday" by many meteorologists. Additional tornadoes were reported across the Southern Plains as well as in the Mississippi River Valley on April 11–12. Overall, the outbreak killed 58 people and injured 1,927 others. This tornado outbreak resulted from a storm system that was the same storm system that, just a few days later, produced the 1979 Easter flood, which was the worst disaster to befall Jackson, Mississippi in over a century, causing over $500 million in 1979 dollars, forcing the evacuation of over 15,000 residents, and killing one.
