Warm, moist air in the lower atmosphere is what fuels thunderstorms. The warmer, and moister the air is the more energy it can provide. If there is enough energy and other conditions are right, the thunderstorms fueled by this warm air can produce tornadoes.

Moist air and warm air are important factors in tornado formation, but they alone do not directly create tornadoes. Tornadoes are typically formed in the presence of a strong updraft within a supercell thunderstorm, where rising warm, moist air can be horizontally spinning at different speeds. The interaction of various atmospheric conditions, such as wind shear and instability, are also crucial in tornado development.
The colliding air masses in Tornado Alley are warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. This collision is just part of the recipe for tornadoes.
Stationary Front
Yes. The warm air mass that often plays a role in tornado formation is called a maritime tropical air mass.

The warm, moist air involved in tornado formation usually comes from a warm body of water. For the United States it is usually the Gulf of Mexico.
A tornado is poweered by the thunderstorm that porduces it. This storm is fueled by warm, moist air.
A tornado may start dying due to a decrease in the warm, moist air feeding into the storm, or if it becomes wrapped in rain-cooled air that stifles its rotation. Additionally, if the parent thunderstorm that spawned the tornado weakens or moves away, the tornado may dissipate.
The Gulf of Mexico provides warm, moist air.
The Gulf of Mexico supplies most of the warm, moist air.

The warm air usually originates from a tropical or subtropical latitude, usually from over a warm body of water such as the Gulf of Mexico.
When warm air moving above mixes in with cool air moving below.

Tornadoes typically form in a warm air mass, as that is what provides the energy, though it is often near a boundary with a cooler or drier air mass. However, due tot he pressure drop the air in a tornado is cooler than its surroundings.
