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.
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.
It can. Hail often does come before a tornado, but most storms that produce hail do not produce tornadoes.
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.
Since tornado typically form in the rear portion of a thunderstorm they are usually preceded by, thunder, lightning, heavy rain and sometimes hail. This does not always stop before the tornado arrives in which case it is said to be rain wrapped.
The tornado itself is not the cause of the hail. Hail is a phenomenon that occurs with thunderstorms that have strong updrafts. The hail forms as the updraft holds ice pellets aloft as layer after layer of supercooled water freezes to their surfaces. Eventually they become too heavy and fall out of the storm. The strongest updrafts are found in thunderstorms called supercells, which due to their rotation, are also the primary producers of tornadoes.
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.
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.
It can. Hail often does come before a tornado, but most storms that produce hail do not produce tornadoes.
No, if there is a tornado or hail near a window is one of the least safe places to be.
No, the presence of hail does not necessarily indicate that a tornado is imminent. While hail can be associated with severe thunderstorms that may produce tornadoes, it is not a definitive indicator of an imminent 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.
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.
Often, but not always.
Yes, a thunderstorm that produces hail can be a good candidate to spawn a tornado. The strong updrafts that form hail in the storm can also create the necessary conditions for tornado development, such as a rotating updraft known as a mesocyclone. However, not all hail-producing storms will develop into tornadoes.
Tornadoes typically do not produce precipitation themselves. They form from severe thunderstorms that can produce heavy rain, hail, and sometimes even snow or sleet, but the tornado itself is a rotating column of air and not associated with specific types of precipitation.
Yes. The storm that produced the Joplin tornado also produced hail up to 1 inch in diameter in the Joplin area.
