Beausejour, MB F1 Tornado of August 26, 2007

Dugald - Beausejour - Grand Beach

Figure 1 depicts the surface observations at 7:00 pm CDT, which shows a stationary front extending northeast across Southeastern Manitoba and Northwestern Ontario, a low pressure system near Morris with a warm from extending southeast across Minnesota and a cold front extending into North Dakota. The complex interaction between the warm front, low pressure and stationary front became the focus for intense thunderstorms in the evening hours of August 26th, which ultimately led to this tornado.
