Figure 1 depicts the surface observations at 1:00 pm CDT, which shows a low pressure system on the Saskatchewan/Manitoba border with an occluded front extending southeast across Manitoba and a stationary front across central Manitoba. The complex interaction between the occluded front and the stationary front triggered thunderstorms across central Manitoba in the afternoon hours of July 31st, which ultimately led to this tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 4:32 pm CDT near Thompson, MB. The path and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or documented property damage.
