Tornadoes are made by thunderstorms, made by cumulonimbus clouds. They appear as very tall white puffy clouds with a dark base and an anvil shaped top. Thunderstorms that can produce tornadoes also have a corkscrew appearance or with striations in the cloud tower.
Tornadoes often have the appearance of being shaped like a rope, or a giant cone or column.
Signs to look for: a lowering of the cloud base rotation in the clouds a hole in the clouds at the back of a thunderstorm Swirling dust beneath the lowered clouds
The funnel clouds of a tornado often range from white to gray to black.
Altocumulus clouds look like a checker board.
A wall cloud is a lowering of a cloud base that is often seen before a tornado forms. It marks the most intense portion of the mesocyclone, the rotating updraft from which a tornado forms. The links below shows picture of what wall clouds often look like.
Cumulus clouds look like cotton candy.
a funnel
It is also called a tornado!
Nope, but they can come from Cumulonimbus clouds, which are the same clouds that produce thunder and lightning. See the link below for a picture of what they look like.
Tornadoes often form in a type of cumulonimbus cloud called a wall cloud. Look up what a cumulonimbus cloud looks like on Google images.

funnel clouds. Other signs that a tornado may soon occur include a lowering of the cloud base and rotation in the clouds during a thunderstorm.
Tornadoes come in different shapes, and the shape changes during the life of the tornado. Some tornadoes are like thin tubes or ropes, some look like large wedges. If it is wrapped in rain, or there isn't enough light, it can be hard to see a tornado. Sometimes clouds may look like a tornado but aren't, so looking for other clues like rotation is important.
There is no particular sky color that indicates a tornado is coming. It is often reported that the clouds look green before and during tornado. But this does not necessarily indicate a tornado, nor is it necessary for a tornado to form. The clouds in a tornadic storm may also appear gray or black.
A cone-like dip in the clouds with tornadic motions which will often precede the touchdown of a Tornado.
The funnel clouds of a tornado often range from white to gray to black.
A tornado is a vortex and may also contain vortices. A vortex is a rotating body of liquid or gass. In a tornado, the vortex is made visible by condensation or dust and debris. It may look like a cone, tapering appendage, or column attatched to the clouds, or may take the appearance of a tube or swirling mass of dust.
you will see Cumulonimbus clouds before a tornado which are large, dark, anvil-shaped clouds.
