supercell

Tornado-spawning storm

A supercell is a severe thunderstorm characterized by a deep, persistently rotating updraft called a mesocyclone.

Supercells are the most dangerous type of thunderstorm, capable of producing large hail, damaging winds, and tornadoes.

They can persist for hours and travel hundreds of miles: The supercell spawned multiple tornadoes across the county.
