Boyle, AB F0 Tornado of July 14, 1981

Westlock - Barrhead - Athabasca


Figure 1 depicts the surface observations at 7:00 am EST, which shows an area of low pressure and a stationary front across Southern Saskatchewan. The interaction between this front and low pressure was likely responsible for triggering thunderstorms across Alberta in the afternoon hours of July 14th, which ultimately resulted in this tornado.
