The scientific reason for strong thunderstorms forming in Ontario

A series of thunderstorms developed near Sarnia, Ontario, on Saturday morning, and extended over southern Ontario toward Ottawa in the afternoon. Destructive winds were reported over a large area of southern Ontario, downward winds caused by severe thunderstorms.

Experts in Arab weather point to the reason why strong thunderstorms usually form during the spring in some regions of the United States and Canada, as a result of the convergence of warm and humid air coming from the Gulf of Mexico with polar air coming from the north. This convergence results in severe cases of atmospheric instability and storms Strong thunderstorms with downward winds, and storms sometimes develop into tornadoes.
