Rodney, ON F0 Tornado of May 13, 2005


Witnesses observed the tornado touch down at 8:45 pm, a long tube of swirling dust that was rotating in an anticyclonic direction. Trees were snapped, crops damaged and lawn furniture thrown around. It was on the ground for 5 kilometres and had a width of 30 metres.

Figure 1 depicts the surface observations at 8:00 pm EDT, which shows a warm front advecting into southwestern Ontario. This brought southeasterly winds, which moved over the open waters of Lake Erie. Interactions with this warm front and possibly with lake-breeze boundaries led to thunderstorm development in the evening hours of May 13th, which ultimately led to this F0 tornado.
