The thunderstorms that produce tornadoes often form along cold fronts, when a old air mass pushes into a warm air mass. The cold front develops when a low pressure system (which rotates counterclockwise in the northern hemisphere) pulls cold air from the north. For U.S. storm systems this cold air is pulled down from Canada.
