One day after an F4 tornado struck the southern Oklahoma City metropolitan area on May 8, 2003, a single supercell thunderstorm produced ten tornadoes in central Oklahoma, including one F3 and three F1 tornadoes in the northern Oklahoma City metropolitan area. This thunderstorm developed in southwest Oklahoma along a retreating dryline. The storm moved northeast across Oklahoma and eventually dissipated in northeastern Oklahoma. One of the tornadoes occurred in the NWS Tulsa forecast area near Depew, OK. Most of the tornadoes occurred after dark. Large hail and strong straight-line winds associated with the rear-flank downdraft also occurred with this tornadic supercell. Other severe thunderstorms produced damaging large hail and strong winds across portions of Oklahoma.
