Opportunity for severe weather moves eastward in Ontario, Quebec
A chance for more severe weather will reappear in Ontario and Quebec on Thursday, but the centre of attention will shift farther east in both provinces.
After a stormy Wednesday evening in southern Ontario, including a tornado-warned cell and multiple areas seeing more than 50 mm of rain, the risk for severe weather will bubble up again on Thursday.
However, the severe chance will be more centred on eastern sections and into southern Quebec as the conditions will be more favourable. Folks there will face a threat of widespread, scattered storms Thursday afternoon and evening, with heavy downpours, near two- to four-centimetre-sized hail and strong winds as the main hazards.

The Greater Toronto Area (GTA) won’t be in the clear, either, as there could be storms popping up there, too, but they should remain below severe warning criteria.
You'll want to stay updated on the weather alerts in your area as conditions can change quickly when severe weather hits.

By the afternoon, expect another risk for widespread, scattered storms, bringing heavy downpours, near two- to four-centimetre-sized hail and strong winds.
Significant instability will fill the St Lawrence Valley, and ample moisture will stretch north into the Laurentians, bringing a localized flooding threat.
The GTA will see the risk of a few storms developing as the Lake Ontario lake breeze interacts with the Niagara Escarpment and the Oak Ridges Moraine, in the late-afternoon and early-evening periods.
The same risk will occur inland from Lake Erie. With these storms, heavy rain will be the only hazard.
