Tornado Alley
States such as Missouri, Iowa, Minnesota, Wisconsin, Illinois, Indiana, and western Ohio are sometimes included in Tornado Alley. Research suggests that tornadoes are becoming more frequent in the northern parts of Tornado Alley where it reaches the Canadian prairies.
Nebraska
Nebraska is located in Tornado Alley. Thunderstorms are common during both the spring and the summer. Violent thunderstorms and tornadoes happen primarily during those two seasons, although they also can occur occasionally during the autumn. The chinook winds from the Rocky Mountains provide a temporary moderating effect on temperatures in the state's western portion during the winter.
