Best Answer

This is the most common cause:

When a low pressure system (which rotates counterclockwise in the northern hemisphere) moves across tornado alley it pulls warm moist air up from the Gulf of Mexico, cooler air down from Canada, and drier air from the Rockies, triggering strong thunderstorms. The Rockies also create a change in wind speed and direction with altitude called wind shear, which allows those storms to produce tornadoes.
