Around this low-pressure system, but more specifically along the cold front, more thunderstorm activity is possible, with large hail and strong winds being the greatest threats, according to Environment and Climate Change Canada.

This will not be the only opportunity to see shower activity with the risk of thunderstorms. Tuesday, more low pressure will move in from the south and keep conditions hot and humid. There is a chance heat warnings will be issued by Environment and Climate Change Canada as daytime highs and overnight temperatures are forecasted to be very close to the warnings criteria. There will again be a risk of severe weather on Tuesday, likely focusing more towards the southwest.
