The Weather Network has great news for those who love the heat! An update published on Saturday morning says “no relief in sight for the stifling heat and prolonged dry spell in southern Ontario…”

Environment Canada Heat Warning Issued at 10:53 Saturday 04 July 2020 –

A prolonged period of hot weather is expected through the weekend into next week.

Daytime high temperatures in excess of 30 degrees Celsius, with humidex values in the high thirties to low forties, are expected for the foreseeable future. Overnight lows near 20 degrees Celsius are also expected through this period, providing little relief from the heat.
