Heat warnings continue for much of southern Ontario on Thursday, the day after Toronto tied a weather record.

On Wednesday, the city tied the record for the hottest Aug. 11 ever. The record high of 35.6 C was set back in 1944, 680 NEWS meteorologist Jill Taylor said, and was reached again on Wednesday.

The hottest day so far this year is still July 13, at 36 C.

As for Thursday, Toronto residents can expect a high of 33 C, with the humidex near 42. There is a slight chance of a shower or isolated thunderstorms after4 p.m., and the possibility of scattered showers and thunderstorms after 9 p.m., Taylor said.

Environment Canada issued a heat warning for much of southern Ontario, including Toronto and the GTA, on Monday. A special air quality statement warning of a possibility of deteriorating air quality from the morning until about 7:30 p.m.

On Tuesday, Toronto’s acting medical officer of health issued a heat warning for the city. During heat and extended heat warnings, the city opens its cooling centres.

The national weather agency said a hot and humid air mass is expected to continue until Friday with daytime temperatures between 31-34 C on each day.

“Afternoon humidex values are expected to peak in the high thirties to low forties,” Environment Canada said in a statement.

Earlier this week, the national weather agency said this may be the “longest and most significant heat wave of the summer so far.” A heat wave is three consecutive days when the maximum temperature is 32 C or higher.

Environment Canada said “slightly cooler temperatures” are in store for this weekend. Taylor said a high of 30 C is expected on Saturday under mainly cloudy skies accompanied with showers or thunderstorms. Sunday will be more comfortable with a high near 27 C.
