Figure 1 depicts the surface observations at 7:00 am EST, which shows a low pressure system across Central Albert with a cold front across Southwestern Alberta. The cold front became the focus for thunderstorms, which ultimately led to this tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 8:00 pm MDT near Finnigan, AB. The path and width of the tornado was not documented by ECCC.
