The other tornadoes that occurred in Southern Ontario during this small tornado outbreak included a high-end F2 tornado at Gads Hill, an F1 at Winthrop, and another F2 that struck Mitchell.
Figure 1 depicts the surface observations at 5:00 pm EDT, which shows a stationary front across southern Ontario. This front became the focus for intense thunderstorms across southern Ontario, which ultimately resulted in two F2 tornadoes, one F1 tornado and one F0 tornado.
