Warm and muggy weekend ahead for Ontario
Saturday, June 28, 2014, 4:12 PM - The temperature is rising in southern Ontario, and with it the chance of storms.
"It was warm and sunny for most of the regions yesterday, and these conditions are expected to continue today," Weather Network meteorologist Brett Soderholm said Saturday morning.
The humidity will keep rising as the weekend progresses.
"Humidex values between 35 and 40 are forecast for southern Ontario and southern Quebec through Canada Day accompanied by a risk of thunderstorms each day," Soderholm says.
Thunderstorm risk on Saturday is expected to focus north of Lake Ontario and in the Niagara and Windsor regions, due to daytime heating and lake boundaries.
A low-pressure system is slowly approaching Ontario, likely beginning to have an impact on the province by Sunday.
"With humidex near 40 around southern Ontario, there is a chance of isolated severe thunderstorms in the province Sunday afternoon into the evening," says Brian Dillon, another meteorologist at The Weather Network. "Showers will be very spotty, so some areas might not receive a thunderstorm."
However, any thunderstorms that do pop up will likely be accompanies by heavy rain and dangerous lightning.
Northwestern Ontario, meanwhile, is in for storms spilling into the region from a system impacting the Prairies and U.S. midwest.
Non-severe thunderstorms were forecasted for the region Friday, and the risk will be for severe storms in Saturday, with a chance of hail, gusty winds (although it is worth it to remember that all thunderstorms have the potential to produce an isolated tornado)..
No severe thunderstorm watches or warnings are in effect for Ontario at this time.
