21 April 2002 - Southern Illinois Supercells

Summary

During the afternoon of 21 April 2002, several supercells developed over southern Illinois and spread into southwest Indiana. This case provides a challenging scenario in that the supercell storm that produced a deadly tornado was 90-100nm away from the nearest radars. Also, interaction with a stationary boundary played an important role in the development of severe weather.
