Figure 1 depicts the surface observations at 5:00 pm EDT, which shows a low pressure over Georgian Bay with a cold front stretching into Michigan. This cold front became the focus for intense thunderstorms in the evening hours of August 2nd, which ultimately led to a tornado outbreak across southern Ontario.
