Wall clouds are what many tornadoes, especially the strongest ones, will spawn from. They are a lowering of the cloud base in the vicinity of the rotating updraft, or mesocyclone.

Tornadoes USUALLY are spawned by supercell thunderstorms, which from a distance will just be very tall and ominous looking storm clouds. Closer up, MOST tornadoes will come from a wall cloud. This will look like a rotating lowering in the clouds. Not all supercells and wall clouds spawn tornadoes, but many do.

They look like funnels coming down from the atmosphere and form.Thus at first they look like a wall then comes the cone like feature.
