Ontario will see temperatures that feel hotter than 30 C this week

If you're not ready to bid farewell to patio season just yet, you'll have one last stretch of summer weather to enjoy this week in Ontario before cooler, classic fall conditions settle in.

While there have been signs of frost across the province already, a ridge of high pressure moving in from the Prairies will bring a period of dry, warm conditions to the province this week. 

From Monday through Thursday, temperatures will rise back to the sweltering conditions experienced over the summer, reaching the mid-to-upper 20s in southern Ontario and around the Golden Horseshoe. 

By midweek, some areas, including southwestern Ontario, could see humidex values at or above the 30 degrees C mark. According to The Weather Network, it's expected to feel like 31 degrees C on Thursday in Windsor, and 30 degrees C in other municipalities like Chatham-Kent, Hamilton, and Kitchener.

The warm temperatures will also land right here in Toronto through the week. On Monday and Tuesday, we'll see a high of 24 degrees C, and on Wednesday, the daytime high is expected to reach 26 degrees C. Don't even think about pulling out your long sleeves on Thursday, because maximum temperatures are estimated to reach 28 degrees C, with a humidex value of 29 degrees C. 

For comparison, the normal daytime highs for this time of year are 21 degrees C in Toronto, and 23 degrees C in Windsor. 

Although hot, these conditions will be short-lived, and if you're desperate to switch out your cold drinks for steaming pumpkin spice lattes, you'll be happy to hear that conditions will quickly cool down by the weekend. 

On Friday, we'll see a high of 22 degrees C, and by Saturday, that number will drop down to 19 degrees C, with a nighttime low of 10 degrees C. Last year, mean temperatures during the week of Sept. 15 to 21 were between 19.9 degrees C and 21.7 degrees C, according to Environment and Climate Change Canada. 

Depending on where you land on the fall-loving spectrum, I think we can all agree that one last stretch of summer-like weather is much appreciated, especially considering that we'll have months of bitterly cold and icy storms to battle out before we see the return of summer once again.
