While hail and tornadoes can occur during the same severe thunderstorm, hail itself does not necessarily indicate the presence of a tornado. Hail is formed when strong updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere, causing them to freeze and form ice pellets. Tornadoes, on the other hand, are violent, rotating columns of air that extend from the base of a thunderstorm to the ground. Tornadoes are associated with intense wind circulation and a characteristic funnel cloud.nnIt's important to note that both hail and tornadoes are often associated with severe thunderstorms. Large hailstones can indicate the presence of a severe thunderstorm with strong updrafts, which may also create an environment conducive to tornado formation. However, the occurrence of hail does not necessarily mean a tornado will form.
