The year is 2014, 12 years after portals linked Earth with Equis. The weather is no longer able to be controlled in Equestria and storms develop. Tornadoes develop outside of towns, but rarely enter the cities. Everyone has learned to adapt to the new weather pattern and move on with lives since putting the weather back under pegasi control would be impossible. On April 12th, 2014, a tornado outbreak starts in the central United States. Most of the storms stay in the U.S. Other storms travel through a portal in the central U.S and enter Equestria near Ponyville. Many supercells develop in Equestria forming the worst tornado outbreak in Equestrian History. The American and Equestrian Storm Chasers team up and chase storms in Equestria to find out how the storms enter the portals and how it is altering Equestria's weather and if possible, improve Equestria's building methods to American-Style. How bad will the tornadoes be and will the ponies of Equestria be able to recover? The Chase is on!
