It was the first burst of fall weather for central and northern Ontario residents this weekend. Sunday saw temperatures dip down to the freezing mark or below for places like Gravenhurst, Ottawa and Chapleau.
“According to satellite radar maps, the areas that were the coldest saw an area of arctic high pressure, clear skies and light winds,” explains Brian Owsiak, a meteorologist working at The Weather Network.
And it looks like Sunday's morning temperatures are a good indicator of what is to come. The Muskoka Region is expected to hit 1°C during the overnight hours, while Sudbury residents could see their breath when the mercury drops to -2°C. These temperatures are below seasonal and for Muskoka, that's the coolest weather expected all week. It's similar to Saturday's weather, when snow flurries were reported throughout the region.
Meanwhile, Toronto has been feeling chilly as well. It's been a crisp weekend for events around the city and Sunday morning saw a high of 6°C across the city. If you think that's cool, you should prepare yourself for Monday. Not only is a frost warning in effect for parts of southern Ontario, you're definitely going to need your warm socks and boots. The high is forecast at 13°C but the low could reach a frigid 3°C.
The chilly conditions have come in step with shorter days and less daytime heating. In the summer, the sun's rays hit the Earth in a way that optimizes heating.
But now that it's fall, the sun is radiating at a different angle. “You don't get that intense heat, as you do in the summer,” says Michelle Cassar, a meteorologist at The Weather Network.
