"Conditions are favourable for the development of severe thunderstorms that may be capable of of producing strong wind gusts and large hail," warned Environment Canada in a severe thunderstorm watch issued for northern Ontario early Monday. "Take cover immediately, if threatening weather approaches."
The thunderstorm risk will sink south on Monday afternoon, but the greatest chance for severe storms in southern Ontario will be on Canada Day Tuesday.
"An impeding cold front will trigger severe weather for southern Ontario and southern Quebec Tuesday," says Weather Network meteorologist Brian Dillon. "These thunderstorms have the potential to produce torrential downpours and gusty winds."
The heat and humidity are expected to persist on Canada day, however the approaching cold front will bring cooler and less humid conditions for the remainder of the week.
