A cumulonimbus incus is a mature thunderstorm cloud generating many dangerous elements. Lightning: this storm cloud is capable of producing bursts of cloud-to-ground lightning. Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft).
The average thunderstorm has a 24 km (15 mi) diameter and a height of approximately 12.2 km (40,000 ft). Depending on the conditions present in the atmosphere, these three stages take an average of 30 minutes to go through.
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning [1] and its acoustic effect on the Earth's atmosphere, known as thunder. [2] Relatively weak thunderstorms are sometimes called thundershowers. [3] Thunderstorms occur in a type of cloud known as a cumulonimbus. [4]
A weather radar image of a mesoscale convective vortex (MCV) over Pennsylvania with a leading squall line. A squall line, or quasi-linear convective system (QLCS), is a line of thunderstorms, often forming along or ahead of a cold front. In the early 20th century, the term was used as a synonym for cold front (which often are accompanied by ...

A derecho (/ ˈ d ɛ r ə tʃ oʊ /, from Spanish: derecho [deˈɾetʃo], 'straight') [1] is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system. [2] Derechos cause hurricane-force winds, heavy rains, and flash floods.
