Precipitation is a key factor in the formation of tornadoes. Tornadoes often form within thunderstorms, where strong updrafts and downdrafts can lead to the development of a rotating column of air. The presence of precipitation can add instability to the atmosphere, enhancing the conditions necessary for tornado formation.

Tornadoes can be associated with hail and heavy rain, but their formation does not involve precipitation. Tornadoes form from severe thunderstorms where strong updrafts of warm, moist air create a rotating column of air that extends to the ground.
Tornadoes are typically associated with heavy rainfall, hail, and sometimes lightning. The strong updrafts within a tornado can cause water droplets to be lifted into the cloud where they freeze and form hailstones.
Tornadoes can form in a variety of weather conditions, including during times of lower precipitation. The key factors for tornado formation are atmospheric instability, wind shear, and a triggering mechanism like a front or storm system. While higher levels of moisture and instability can increase the likelihood of tornadoes, they can still occur with 20 percent precipitation if other conditions are favorable.
During a tornado, heavy rain and hail are the most likely types of precipitation that may fall. Tornadoes are often associated with severe thunderstorms that can produce intense rainfall and hail as the storm system intensifies.
Precipitation in a tornado occurs when the strong updrafts within the tornado lift moisture-laden air to higher altitudes where it cools and condenses into rain or hail. The rotating winds within the tornado can help enhance the formation and intensity of precipitation.
