In this study, we examined 86 tornadoes using WSR-88D archive IV data.  In some cases archive III data was used where archive IV data was not available.  Each case was examined to determine the structure of the tornado producing thunderstorm.  It should be noted that some tornadic storms exhibited several characteristic during their life cycle.  For example,  supercells were observed in lines of thunderstorms; a boundary interaction involving a supercell may have resulted in tornadogenesis; or a supercell evolved into a bow echo.
