Because only the the energy involved in a thunderstorm or developing thunderstorm is enough to form something as strong as a tornado.
Thunderstorms form from cumulonimbus clouds, but they don't have to be low. Some of these thunderstorms can produce tornadoes, but not all. A thunderstorm is the only thing that can produce a tornado. Tornadoes form best from low-based thunderstorms.
First. A wall cloud is not a cumulonimbus clouds, but is a smaller cloud that extends from the base of a cumulonimbus. Tornadoes often form from wall clouds.
Tornadoes are associated with funnel clouds.
tornadoes can form every where
thunderstorms and other intense weather. Cumulus humilis clouds, appearing as small or medium-sized puffy shapes in the sky, often occur in times of fair weather. However, cumulus clouds can grow into cumulonimbus clouds which may produce heavy rain, lightning, severe and strong winds, hail, and even tornadoes. Cumulus congestus clouds, which appear as relatively thin towers, will often grow into cumulonimbus storm clouds. Hope this helps
