Tornadoes need thunderstorms to form and they usually form in the updraft portion of a supercell, which is in near the back of the storm.

The downdraft portion, where most of the rain and hail can be found is in the from half.

Does hail occur when there is a tornado?

Often, but not always.


When hail falls does it mean a tornado could come?

It can. Hail often does come before a tornado, but most storms that produce hail do not produce tornadoes.


Can snow occur during a tornado?

No. Tornadoes are often accompanied by rain or hail, but if it is cold enough for snow, it is too cold for a tornado.


Does a tornado have hail?

Tornadoes are often but not always accompanied by hail. However, the hail is not a result of the tornado itself but the storm that produces the tornado.


What happens before a tornado occurs?

rain, hail, and wind happen.


Does the tornado form after the hail?

Not necessarily. Tornadoes typically form in the rear portion of a supercell thunderstorm, while hail is often found further forward. So in many cases and area will get hail before the tornado moves through. But that that does not mean the tornado has not formed yet.


When tornadoes appear does hail come too?

Tornadoes are very often accompanied by hail, but not always. In many cases that hail comes before the tornado.


Why does it hail outside when there is no tornado outside?

Hail does not depend on a tornado. Hail forms in thunderstorms with strong updrafts and turbulence. Many of these storms are not even capable of producing tornadoes as they have a strong enough updraft, but not enough rotation for tornadoes.


What comes before a tornado?

Tornadoes are often preceded by heavy rain and sometimes hail and strong winds as well as thunder and lightning. The rain and hail often stop before the tornado hits, but it may also be embedded in the rain.


What signs would you see if a tornado was going to occur?

Tornadoes occur during severe thunderstorms and so are often preceded by heavy rain, strong winds, and hail. Specific signs that a tornado may soon develop include rotation in the clouds, a persistent lowering of the cloud base in or near that rotation, and a clear slot opening up near the rotation. Some people report seeing greenish clouds before or during a tornado. While this phenomenon does sometimes occur, it is not necessarily associated with tornadoes.


Is a hailstonefrom a tornado?

No. Hail stones are caused by rising air in thunderstorms that blows rain upward to the height of the atmosphere in which temperatures are freezing. Many tornado producing storms have strong updrafts and also produce hail---but you can have hail without a tornado and likewise you can have a tornado without any hail.


Is there snow in a tornado?

No. Tornadoes occur during thunderstorms when the weather is warm. They often occur in a rain-free portion of a storm, but rain and often hail are generally nearby.
