Consider this your official warning that Toronto's weather is expected to be soaring into 40 C territory this weekend.

The Weather Network is calling for damp and humid conditions this weekend, with daytime highs feeling like 35 C on Saturday and 40 C on Sunday.

There's also a risk of rain and thunderstorms on both Friday and Saturday, but Sunday is shaping up to be a dry day, meaning that there will be no relief from the heat.

Intense humidity will persist throughout much of next week, and real-feel temperatures will hover in the upper 30s. A risk of thunderstorms and 34 C with high humidity is the current forecast for Canada Day in Toronto.

Many parts of Ontario can expect a lot of rainfall over the next seven days, with as much as a month's worth of rain expected in some areas.
