Stay indoors

The building heat in Ontario and Quebec this week has created an increasingly unstable atmosphere, which will provide plenty of fuel for thunderstorms.

A stiflingly hot Canada Day is in store for Ontario and Quebec, with daytime highs in the 30s and humidex values in the 40s. The heat and humidity are creating the perfect conditions for severe thunderstorms to develop in some areas.

Also on Wednesday afternoon, severe thunderstorms are possible near Peterborough and areas east towards Bancroft and Ottawa, and will track towards Lake Erie and the international border.With high moisture and humidity in place, torrential rain is the primary threat. Storms could drop 30-50 mm of rain in a short amount of time.

Thursday threat builds again over Ontario, Quebec

Days of intense daytime heating have provided two key ingredients for yet another day of severe weather: instability and moisture. Those combined with an approaching cold front will trigger a risk for severe thunderstorms throughout the afternoon and evening hours on Thursday.

The cold front is forecast to slide southward on Thursday afternoon and evening, triggering a line of thunderstorm development along its boundary. We could see stronger storms with embedded rotation develop northwest of Toronto, around the Guelph area, as well as east of Toronto, around Cobourg. The main tornadic threat, however, will be for the Ottawa area, as there is a better chance for wind shear to spin up the storms.

Toronto saw its hottest-ever Canada Day on Wednesday, July 1, with a daytime high of 36.0°C and a feels-like value of 48. Many communities across Ontario, Quebec, and the Maritimes saw highs well into the 30s with feels-like values into the 40s.
