Ordinary Cell: As the name implies, this is a thunderstorm with
only one cell. It's commonly referred to a 'pulse' thunderstorm.
Multi-cell Cluster: These are thunderstorms that are organized in
clusters of 2-4 short-lived cells. Multi-cell Line: Some
thunderstorms will form in a line which can extend for hundreds or
miles. These 'squall lines' can last for hours and cause a lot of
damage. Super cell Thunderstorms: These are potentially the most
dangerous form of all thunderstorms types. Super cell thunderstorms
have produced numerous long-lived strong and violent (EF2-EF5)
tornadoes, along with damaging wind, hail and flash floods.

thunderstorm can occur in every state. Every thunderstorm produces
