Figure 1 shows the surface observations at 5:00 pm EDT, which depicts a significant occluding low over Hudson Bay. This low is dragging a cold front across the Great Lakes and a warm front in eastern Ontario. The warm front became the focus for deep convection, which ultimately led to this tornado.
