[4] The radar structure of this type of thunderstorm is characterized by overhangs of reflectivity in the southwestern part of the cluster.

This is because there could be severe hail from a strong updraft that lasts only a short period of time, with damaging winds.

The speed and direction at which the entire cluster of thunderstorms move downstream make the difference in the amount of rain received in any one location.

[2] A multicellular storm can sometimes develop into a mesoscale convective system (MCS) or be a squall line.

Updrafts reform new cells continually at the leading edge of system with rain and hail following behind.
