Toronto still under extreme heat warning as summer arrives. Here’s when it’s expected to end

The heat warning is expected to end Saturday morning and by late Sunday a “cold front” is likely to sweep through the region giving us at least a couple days of seasonable weather before temperatures possibly rise again, according to Environment Canada meteorologist Steven Flisfeder. 

A new weather attribution system is working to identify the role of climate change in the immediate aftermath of extreme weather.
