If there is enough solar energy in the atmosphere, however (on a hot summer day, for example), the moisture from one storm cell can evaporate rapidly—resulting in a new cell forming just a few kilometres from the former one.

Most storm cells die after about 20 minutes, when the precipitation causes more downdraft than updraft, causing the energy to dissipate.

Clouds form when the dewpoint temperature of water is reached in the presence of condensation nuclei in the troposphere. When a few letters make a large difference.
