After a sluggish start to spring, the Weather Network is calling for a warm and sometimes stormy summer in southern Ontario.
Temperatures will be near normal across the region with more hot weather expected compared to last year, especially during the first half of summer.
However, changeable conditions are likely with several periods of cooler weather also expected, especially during the second half of the summer.
There is the potential for cooler weather to arrive sooner than normal as early fall approaches, threatening an early end to the growing season.
Throughout the summer, the changeable pattern and availability of abundant Gulf moisture should result in above normal precipitation due to rounds of thunderstorms across the region.
"Ontario and Quebec will once again escape the hottest weather, but this summer will bring more heat than last year, along with ample opportunity for thunderstorms," said Chris Scott, chief meteorologist at The Weather Network.
