Figure 1 shows the surface observations at 4:00 pm CDT, which shows an occluding low pressure over northern Manitoba with a stationary front extending south across Manitoba and a warm front extending east across northern Ontario. The stationary front became the focus for intense thunderstorms across south-central Manitoba, which ultimately led to two tornadoes on this day.
