Supercell thunderstorm over fields. A supercell thunderstorm is a severe long-lived storm within which the wind speed and direction changes with height. This produces a strong rotating updraft of warm air,known as a mesocyclone,and a separate downdraft of cold air. This storm produced hail the size of softballs.
