What causes tornadoes to dissipate is not fully understood, but it is believed that cold thunderstorm outflow undercuts the parent circulation (mesocyclone) that drives the tornado, cutting of the warm air that drives the thunderstorm, causing it to weaken to the point that it can no longer sustain a tornado.
