Two weather systems, one from Alberta, the other up from Texas, are expected to meet over the Great Lakes region early Thursday, turning out heavy rain and strong winds.
Rain — possibly preceded by snow, freezing rain or ice pellets — will hit Toronto by midday as the storm moves east from the Windsor-Sarnia area towards Kingston.
The rain will continue until Friday, and there is also a chance of thunderstorms. Additionally, the warm, wet weather may lead to “significant snow melt”, according to the weather service.
A new layer of snow fell on Toronto earlier this week and, with temperatures expected to hit 3 C on Thursday, there is fresh concern the city could experience some flooding.
