Yes. Tornadoes form from strong thunderstorm which, of course, bring clouds.
you will see Cumulonimbus clouds before a tornado which are large, dark, anvil-shaped clouds.
A tornado is formed from storm clouds. The funnel cloud is the tornado before it touches down.
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.
Tornadoes are produces by cumulonimbus clouds. Often a wall cloud and/or funnel cloud are seen before or during a tornado.
The funnel clouds of a tornado often range from white to gray to black.
The clouds in tornadoes are called funnel clouds.
It varies but most often it stops raining a few minutes beforehand. A break in the clouds may be seen, a sign of a downdraft that helps the tornado form. A number of tornado survivors recall it being unusually quite just before the tornado hits.
The only cloud you will actually find inside a tornado is the condensation funnel. Other clouds, such as the wall cloud and cumulonimbus are outside the tornado itself.
Cumulonimbus clouds can spawn a tornado.
Tornadoes are produced by cumulonimbus clouds. Often a wall cloud appears near the base of a cumulonimbus before a tornado forms.
They don't need to be any color in particular. Though they are often green. The clouds near a tornado and even the tornado itself may appear orange if it occurs near sunset. Clouds near a tornado can also be gray or black.
There is no set size for a wedge tornado. Generally a wedge tornado is one that appears to be wider than the distance from the clouds to the ground and the height of the clouds can vary.
