The map says it all...warm = red

Warm & humid summer
Environment Canada has had a stellar year at long term forecasts. They predicted our snowy, "old fashioned" winter and nailed the cool and damp spring. And now....get ready for a hot summer. The 3 month forecast recently released is calling for very hot and humid weather across Ontario and Quebec through August. Most of the country as a matter of fact will be warmer than average. You will not have to wait too long for this to take effect. The forecast for this upcoming weekend is warm and humid. While there are numerous showers and thunderstorms expected in the tropical like airmass, it will not be a wash out. The muggy weather begins today with a high of 25-27C in most areas and humidex values approaching 30C.
On Friday and through the weekend daytime highs will be 30-32C with humidex values approaching 40C!

Remember winter, you know that big snowstorm that closed highways and dumped 50cm in one shot, yeah neither do I!
Be safe drink lots of water and get the A/C up an running.
