Figure 1 shows the surface observations at 4:00 pm CDT, which shows a low pressure system on the North Dakota/Manitoba border. This low would have brought southwesterly flow across southern Manitoba. Terrain interactions with the Manitoba Escarpment and possible lake-breeze interactions from Lake Manitoba likely triggered thunderstorms in southwestern Manitoba, which ultimately led to this tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 4:20 pm CDT near Neepawa, MB. The track and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or property damage.
