Figure 1 shows the surface observations at 7:00 am CDT, which shows a low pressure in south-central North Dakota with a trough of low pressure extending north across southern Manitoba, a cold front extending south across South Dakota and a warm front extending east across Minnesota. The trough was the focus for an intense thunderstorm across southeastern Manitoba, which ultimately led to this tornado.
