Multicell Cluster Storms a cluster of storms in varying stages of development A multicell cluster consists of a group of cells moving as a single unit, with each cell in a different stage of the thunderstorm life cycle.
Multicell storms can be broken down further into the categories of multicell line and multicell cluster storms. The "intense" updraft storm is almost invariably the supercell, a storm capable of producing the most devastating weather, including violent tornadoes.
On the thunderstorm spectrum, supercells are the least common type of thunderstorm, but they have a high propensity to produce severe weather, including damaging winds, very large hail, and sometimes weak to violent tornadoes.
