Tornadoes can occur in most areas, but they occur more frequently in some places thanin others. Tornadoes form best under a given set of circumstances when a mass of cool and/or dry air pushes into a warm, moist unstable air mass with the right setup of wind shear, or a difference in wind speed and dirction with height. This leads to the formation of rotating thunderstorms that can spawn tornadoes. This setup occurs more frequently in some areas than in others.
