There are three different stages of a thunderstorm. The first stage is the cumulus stage. The cumulus stage is when warm are rises, or updrafts, and the clouds begin to grow bigger. The second stage is the mature stage. This stage is when the cloud is at its largest, it has a large amount of water, and precipitation occurs. The last stage is the dissipating stage. In this last stage the precipitation cools the cloud down, and the storm begins to die down.
