So, what happened? 

A strong area of low pressure pushed a warm front through the Miami Valley from the southwest. This opened the door for a very unstable environment to move in. As the low approached, clusters of severe thunderstorms with rotating updrafts enter the region from the west. Once these storms encountered the very unstable air mass in place, they rapidly intensified.

While there were many injuries and one death reported, that number could have been much higher. Advancement in radar technology and the ability to get severe alerts out to the public with as much lead time as possible likely limited the injury and death toll.
