A thunderstorm does not become a tornado, it producesone.

In order to produce a tornado a storm first needs a strong, rotating updraft called a mesocyclone. A storm with this feature is called a supercell. The rotation in a mesocyclone the tightens, intensifies, and extends towards the ground, becoming a tornado.

How this intensification occurs is not fully understood, but it is believed that a downdraft at least plays a role by wrapping around the mesocyclone and forcing it into a tighter circulation.
