Severe thunderstorm, tornado warnings for parts of Ontario
· Toronto Sun

Environment Canada issued a severe thunderstorm watch for southern Ontario, in particular communities west of Ottawa such as Bancroft, Kaladar and Pembroke, and Midland southwest towards Sarnia late this afternoon and into the evening.
Tuesday’s severe weather risk could bring strong winds, hail, lightning and possibly a tornado, according to forecasters. The weather is predicted to be strongest in those parts of Ontario, and is expected to weaken once it approaches Toronto and the Golden Horseshoe.

Currently, Toronto is under a “slight” to “strong” risk of severe weather. Thunderstorms are expected during the late afternoon and early evening. Forecasters say watch out for wind gusts exceeding 100 km/h and ping pong ball-sized hail. The stormy weather is expected to calm down later on in the evening, likely between 9 p.m. and 10 p.m., as the lack of daytime heat weakens the intensity of the thunderstorms.
And then it gets cold
After the storms, a cold front is expected to descend on Southern Ontario overnight, putting an end to the province first major heat event of the year. By Wednesday, some Ontarians could be waking up to single digit temperatures. There may even be some risk of frost for some parts of Central Ontario as the cool air settles back into the province.
Toronto has seen an unusually early heatwave over the holiday weekend and early into this week, with temperatures reaching 30 C and the humidity making it feel like 35 C. Environment Canada issued a yellow heat warning for the province that spanned from Windsor and Niagara though the GTA and up to Collingwood.
