The daytime high will be around 24 C in Mississauga, but could feel more like 30 C due to the humidity. It could feel as warm as 31 C in Oshawa, Pickering, Vaughan and Richmond Hill.

Conditions are expected to clear into the evening hours with a low of around 17 C in Toronto and 14 C in Mississauga.
