Thunderstorms should spell end to Toronto heat

The uncomfortable weather that has descended on Toronto should start moving off by Saturday, but not before some rain and thunderstorms drench the region.

Environment Canada has issued an alert saying there is a "risk of severe thunderstorms this evening and after midnight" along with some strong winds.

But that will probably be the last gasp of the heat wave that has broiled the city for the past five days.

Temperatures stayed in the mid-30s for most of the week. And with the humidity figured in it felt a lot more like 40 C, or higher.

The city declared an extreme heat alert, opening cooling centres, advising people to look after themselves and check on elderly neighbours, and keeping many neighbourhood swimming pools open late into the evening to help people stay cool.

But on Saturday the sting from the heat is expected to fade.

Environment Canada is forecasting a beautiful, sunny summer weekend for Toronto with a high of 27 C and an overnight low of 15 C.
