It's going to feel like 46 degrees in Toronto this week

Following an intense, record-breaking heat dome that swept across southern Ontario over Canada Day, the region is bracing for yet another round of sweltering temperatures this week.

According to The Weather Network's 7-day forecast, conditions in Toronto will start heating up Monday afternoon, when we're expected to see a daytime high of 32 degrees C, which will feel much closer to 37 C with the humidity.

Nighttime lows will provide very little relief from the heat at 24 C, which will still feel like 29 C, factoring in the humidity. Temperatures will reach a peak on Tuesday, when the morning temperature will quickly increase from 26 C to 37 C in the afternoon, reaching a humidex value of 46 C.

The last time temperatures got this sizzling was on July 1 this year, when the daytime high of 36 C felt closer to 44 C. On the day Toronto hosted the round of 32 FIFA World Cup match between Portugal and Croatia, temperatures reached 34 C (which felt closer to 43 C).

According to The Weather Network, if Toronto actually sees a high of 37 C on Tuesday, it could mark it as the hottest temperature of the year so far, surpassing the 36 C recorded on Canada Day.

Luckily, the brutal heat won't stick around for too long, as a cold front is expected to sweep into Ontario late Tuesday, which should bring Wednesday's temperatures back down to the low-30s mark. Thursday's daytime high will be 31 C, and overnight lows will drop to 22 C, providing some much-needed relief following the heat wave.

As a result of the upcoming heat wave, Environment Canada has issued a yellow heat warning for the City of Toronto, which is expected to end either on Wednesday evening or Thursday evening.

"Tuesday will mark the peak of this heat event. Maximum temperatures on Tuesday near 37 degrees Celsius are expected for some areas over southwestern Ontario, around the Greater Golden Horseshoe and eastern Ontario," the alert reads.

"Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category."

The government department advises drinking water frequently, closing your blinds and shades, and turning on your air conditioning, using a fan, or moving to a cooler area of your living space.
