Ontario's weather is going to feel like fall next week with "unseasonably cool" conditions.
Some parts of the province will even get single-digit overnight temperatures!
The Weather Network has revealed that Ontario is in for "a significant temperature drop" and a hint of early fall during the last week of August.
That's because Hurricane Erin is moving across the Atlantic Ocean and influencing the jet stream over eastern parts of Canada.
It will lead to "unseasonably cool weather" in Ontario.
A cold front bringing the potential for thunderstorms is forecast on Sunday, August 24.
Then, the colder and drier air will settle over the province, according to The Weather Network.
Temperatures will "drop significantly" on Monday, August 25.
It's forecast to be cooler than normal in Toronto with temperatures in the low 20s, which is 5 C below seasonal for this time of the year.
According to The Weather Network, most major cities haven't had daytime highs of 20 C since early June.
On Tuesday, August 26, it will be 20 C in Toronto and Ottawa, 19 C in London, 18 C in Huntsville and Sudbury, 17 C in Sault Ste. Marie and 16 C in Timmins.
Single-digit overnight lows are forecast for many cities, towns and communities in the northern parts of Ontario.
The Weather Network said that cooler weather and warm waters of the Great Lakes will increase the risk of waterspouts and lake-effect showers.
It's expected that these below-normal temperatures will continue into early September, before there's a warm-up heading into the Labour Day long weekend.
Looking ahead to the next season, Canada's fall forecasts have revealed when provinces will get chilly temperatures and snow.
The fall forecast for Ontario calls for a cool and dry start, but a "very unsettled" and cold end to the season.
Heavy showers and thunderstorms are expected throughout October, along with a chance of "early snow."
Then, widespread snowfall is expected in Ontario by November.
