The active weather – that will prevail over most parts of Ontario – will be associated with an area of a low pressure system moving through northern Ontario.
“We are guaranteed to see thunder, rain and hail as a result of this system,” says Rob Davis, a meteorologist at The Weather Network.
That first wave is expected to move into southern Ontario late Tuesday night and track through the area into the overnight hours. The affected areas could see scattered showers with the chance of some non-severe embedded thunderstorms. That should last into the early morning hours on Wednesday. The showers will gradually track eastwards.
The next potential for thunderstorms will be ahead of a cold front later in the day on Wednesday.
“The storms we are keeping a close eye on are the ones associated with the cold front,” says Davis. “It’s expected to move through north eastern and southern Ontario through the afternoon and evening hours on Wednesday.”
The system will start in Nicklebelt and move through to southern Ontario. The risks with the thunderstorms on Wednesday could include hail, damaging winds and high amounts of rain. There's also a possibility for super cells. The storm potential includes places like Goderich, an area that saw much destruction from Sunday’s deadly tornado.
