Figure 1 depicts the surface observations at 4:00 pm CDT, which shows an occluding low pressure in the Manitoba Interlakes and a cold front extending south across extreme southeastern Manitoba. The occluding front was the focus for intense thunderstorms across central Manitoba in the afternoon and evening hours of July 6th, which ultimately led to two tornadoes.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 5:00 pm CDT over Lysay Lake, MB. The path and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or documented property damage.
