Figure 2 depicts the surface observations at 2:00 pm EDT, which shows a cold front slicing through southern Ontario, a warm front advecting north into Quebec and an outflow boundary near Kingston. This outflow boundary, possibly aided by the forcing of the cold front, triggered thunderstorm development in the early afternoon hours of June 29th near Belleville, which ultimately resulted in a brief F1 tornado.
