The Tornado outbreak of June 27 - 28, 2018 was caused by the interaction of a dryline with a frontal zone over Kansas. This led to the development of a few supercells, which allowed 10 tornadoes to touch down, and led to the NWS SPC issuing an Enhanced Risk for severe weather. A violent EF3 wedge tornado touched down near Wichita, severely damaging or destroying hundreds of buildings in the process. 9 people were killed during the outbreak, with damages reaching $320 million.

A dryline began developing over the Rockies about 36 hours before the beginning of the outbreak, allowing for the build up of a capping system. As the system collided with a frontal triple point over Kansas,it broke the capping cell, and several tornadoes began touching down during the late afternoon and into early the following morning across Kansas, including a violent EF3 that hit Wichita in the blackness of night, causing severe damage in the process. Once the system had moved on, the frontal zone dissipated, leaving no moisture for the dryline to feed off, and so diminishing the storms to longer be severe. The remnant storms dissipated by late that morning, leaving behind severe damage to most areas hit worst.
