Just after 11 pm, a tornado warning was issued for parts of the region including St. Catharines, Grimsby and northern Niagara region.

"At 11:05 pm EDT, Environment Canada meteorologists are tracking a thunderstorm that is possibly producing a tornado," said Environment Canada in the warning. "The thunderstorm is located just northwest of Fenwick and is tracking northeast at 40 km/h."

The warning was dropped shortly after and no tornado touch downs were reported.

2. Heavy rain continues in Ontario and Quebec

A slow moving system continues to bring the threat for heavy rain in parts of Ontario and Quebec Thursday.

LOOK AHEAD: 'Outstanding' Father's Day expected in southern Ontario.

As much as 70 mm of rain has already fallen in parts of eastern Ontario with an additional 20-40 mm possible in some places through Friday.

"Much of the rain will come from thunderstorm activity, as a result, amounts will be quite variable," EC adds.

A special weather statement remains in place for parts of Quebec with up to 70 mm of rain forecast by Saturday morning.

"Exercise caution when traveling to avoid hydroplaning," EC warns.

3. Cover up your plants, Newfoundland

Cool and below seasonal temperatures continue to dominate much of Newfoundland with widespread frost advisories issued for the province. 

There's a risk for frost after midnight on Friday through to early morning on Saturday. 

"Frost may damage some crops in frost-prone areas," EC warns. "Cover up plants, especially those in frost-prone areas."

4. Thunderstorm risk continues for the Prairies

Another day, another thunderstorm risk.

This time the greatest risk for non severe storms will be through northern and central Saskatchewan and in parts of southern Manitoba.

"A new developing low Thursday into Friday will bring a wet couple of days for southern Alberta and Saskatchewan," says Weather Network meteorologist Kelly Sonnenburg.
