Morning Briefing: Four things to know
Sunday, August 3, 2014, 8:30 AM - Many Canadians are midway through a long weekend.
While the weather has been decent across most provinces, there have still been a few powerful storms, and Sunday has more of the same in store.
Read on for how much, where, and when.
Parts of the east coast had some thunderstorm risk in the predawn hours Sunday, although no watches or warnings were in effect.
A weak trough will bring rain to southern Nova Scotia and Newfoundland Sunday, although amounts will be less than 10 mm.
Seasonal and slightly humid conditions will persist for Newfoundland, although a sharp drop in temperature is forecast for Monday and Tuesday.
As with Friday, Saturday afternoon's storms brought hail and torrential rain to parts of southwestern Ontario.
"A lot of rain fell in the Kitchener-Waterloo and Guelph regions yesterday, leading to significant washouts on roads and localized flooding, with more than 60 mm reported in KW," Weather Network meteorologist Brett Soderholm said Sunday morning.
Thunderstorms also struck Quebec Saturday, affecting Quebec City, Trois Rivieres, Montreal and other communities.
It's expected to be a calmer day for much of southern Ontario Sunday, with only a slight risk of non-severe thunderstorms around the shores of lake Ontario.
"Temperatures will be close to seasonal, with a little bit of humidity leading to widespread humidex values in the low 30s," Soderholm says.
On Monday, however, a cold front from a low-pressure system will act as a trigger for evening thunderstorms in southern Ontario.

Thunderstorms flared up around the Cold Lake, Alta., area Saturday night, and along the foothills of Alberta, with severe thunderstorm watches and warnings issued for both regions.
Sunday afternoon a19585151nd evening, a cold front should trigger storms along the Alberta and Saskatchewan border, with severe potential. The greatest threats in that case would be hail and strong winds.
Otherwise, Soderholm says, conditions Sunday should be seasonal, with minimal humidity, although Monday, non-severe storms are possible again in the region.
It's still hot and dry through much of the province, with storms triggering in the Interior Saturday night, with a severe thunderstorm even issued for the Boundary area.
The interior could see thunderstorms again on Sunday, developing in the afternoon and evening.
