Six tornadoes have been confirmed by Environment Canada following the destructive storms from last Friday in Ontario and Quebec.
A Kingston, Ontario man lost his life after a tree fell on him during the violent weather.
Post-storm clean up in the Ottawa-Gatineau area is well underway, but another fall storm deepening over the Great Lakes through Wednesday will toughen the efforts, bringing rain, gusty winds and thunderstorms with a slight, but complex tornado risk back to eastern Ontario and southern Quebec.
On Wednesday, scattered thunderstorms and mainly cloudy skies will prevail across the province. As the region enters the warm sector of the system, an area where instability grows as temperatures rise, the atmosphere will become primed for severe weather ahead of a cold front.
However, this system will be messy and mostly cloudy skies will keep instability on the lower end, with only patches of moderate instability forming as clouds sporadically thin out.
Whatever the system lacks in energy, it makes up for with strong dynamics and wind shear, heightening the threat of damaging wind gusts and a slight tornado risk.
