Most people won’t see one tornado in their lifetime much less two.  But cameras were all over a Nebraska supercell thunderstorm on Monday evening as it produced two tornadoes at the same time!

There are many ways a thunderstorm can produce multiple tornadoes.  One way is for one tornado to die away and back up into the colder part of the storm while a new tornado takes shape, usually to the east or southeast of the old tornado.

Thunderstorms which produce multiple tornadoes like this are called cyclic tornadic supercells.

In the Ozarks, the Stockton tornado of May 4, 2003 was actually the second of a total of three tornadoes produced by one supercell thunderstorm.
