Morning briefing: Four things to know about Saturday
Saturday, June 28, 2014, 8:03 AM - Plenty of Canadians are looking at stormy weather and/or sweltering temperatures this weekend.
Here's a look at who's in for what on Saturday.
People in Newfoundland saw the last of the rain yesterday from a system that dropped around 20 mm of rain on St. John's, which was the coldest provincial capital in Canada on Friday, not even cracking the double digits.
St. John's should get up to the low teens this weekend, warming up to the 20s by Monday.
The Maritimes meanwhile, are in for above seasonal and quiet conditions this weekend, with humidity becoming a factor on Monday and Tuesday for the region.
Ontario and Quebec
Friday, meanwhile, was largely warm and sunny for central Canada on Friday, and those conditions are expected to continue Saturday.
Ottawa, Montreal and cities in the Golden Horseshoe all got up to the high 20s on Friday.
And it's only going to get hotter, according to Weather Network meteorologist Brett Soderholm.
"Humidity will start to build in southern Ontario today, and will increase as the weekend progresses," he said. "Humidex values close to 40 are forecast for Ottawa & Montreal on Canada Day, accompanied by the risk of thunderstorms."
There will be a possibility for isolated thunderstorms north of Lake Ontario Saturday as a result of lake breeze convergence. The Niagara and Windsor regions could also see a late-day storm.
Extreme northwestern Ontario, meanwhile, is at risk for potentially severe thunderstorms, part of a system spilling over from the Prairies.
That system has made for widespread thunderstorm risk across the western provinces.
Severe thunderstorms could develop in Manitoba and parts of Alberta, with Winnipeg, Man., and Edmonton, Alta., included in that zone.
Alberta actually had its second confirmed tornado of the season Friday, a short-lived twister generated near the community of Cremona.
There was no damage reported from that twister, nor were any watches or warnings issued.
For Saturday, it's rain and more rain in Manitoba and parts of Saskatchewan.
"Rainfall warnings are in place for western Manitba and western Saskatchewan as a low-pressure system intensifies throughout the weekend," Soderholm says. "Rainfall amounts are forecast to be highest along the Saskatchewan-Manitoba border, with some regions seeing an additional 60 mm by Sunday night."
Temperature-wise, the Prairie provinces were warm Friday, swelteringly so in Manitoba, with the humidity making it feel even hotter.
But a sharp drop in temperature is forecast for southern Alberta on Sunday, as a cold front sweeps through, with Calgary calling for 14C as a daytime high on Sunday.
Canada's Pacific province will be seeing some risk of thunderstorms through the interior for Saturday.
As for the coast, it's expected to be rainy and unsettled.
"Vancouver is also at a risk of seeing an isolated non-severe thunderstorm develop this afternoon," Soderholm says.
