Hail is formed when ice particles are carried up and down within the updraft of a strong thunderstorm. The pieces of ice pass between air that is above and below freezing multiple times. With each cycle a new layer of ice is added. The stronger the updraft the larger the hail can get before falling.
Note the the storm simply needs to have as strong, turbulent updraft to produce hail and does not have to be tornadic.
Hail most often occurs ahead of the tornado but it also frequently found in the hook of the storm, which wraps around behind and to the left of the tornado (with respect to its movement) in the northern hemisphere and to the right of it in the southern hemisphere.
No. Precipitation is water that falls from the sky in some form, such as rain, snow, or hail. A tornado is basically a violent wind storm. While tornadoes are usually accompanied by rain and often by hail, this precipitation is not directly related to the tornado itself.
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.
The weather is storm as tornadoes are produced by very powerful thunderstorms. The tornado may be surrounded by rain and large hail.
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.
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.

Most often, hail may form because of the updraft that a storm will create. The attached links will give you more information on hail and tornadoes.
a hail storm or tornado.
Tornadoes themselves are not the cause of hail, thunderstorms are. In order to produce hail a storm must have a strong updraft to keep hailstones in the air as they form and a fairly large amount of turbulence to create the cycle that forms hail. Tornadoes also need a strong updraft to form but also need other factors such as rotation in the storm to form, but this rotation isn't needed for hail.
Yes. The storm that produced the Joplin tornado also produced hail up to 1 inch in diameter in the Joplin area.
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.
Yes. This is especially possible if the hail or tornado occurs in an unpopulated area far from the nearest radar site.
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.
Hail
Tornadoes are usually accompanied by rain and are often accompanied by hail.
