Figure 1 depicts the surface observations at 7:00 pm CDT, which shows a trough of low pressure moving east across southern Manitoba and a low pressure across northeastern North Dakota. The interaction between the low pressure and the trough triggered thunderstorms in the afternoon hours of May 22nd, which ultimately led to this tornado.
According to Environment and Climate Change Canada (2018), an F1 tornado touched down at 6:30 pm CDT near Fairfax, MB. The path and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or property damage.
