The central plains of the United States form a region called Tornado Alley, which has an ideal climate setup for tornadoes. In the spring storm systems cause warm, moist air from the Gulf of Mexico to collide with cool air from Canada and dry air from the Rockies, resulting in the formation of strong thunderstorms. About a mile off the ground a layer of stable air holds thunderstorm activity back, allowing instability to build underneath it. As a result when the storm break through the cap the instability will be enormous, leading to explosively powerful thunderstorms. At the same time wind speed and direction varies with altitude, which sets these storms rotating and also strengthens the updraft. This rotation combined with strong thunderstorm updrafts can then produce tornadoes.
Similar conditions can occur elsewhere, but not nearly as often.
