As Summer 2020 comes to a close, Fall-like weather is right on our doorstep. According to national weather forecasters, we’re likely to feel a substantial cool down next week thanks to a huge ridge of high pressure building on the west coast.
That ridge will help to create a trough allowing the jet stream to dip well below the Great Lakes. This colder air will be felt from Saskatchewan, east to the Atlantic provinces. In Northern Ontario there might even be a chance of the first frost of the season as temperatures could struggle to reach 12c for a daytime highs. Overnight temperatures, especially away from large bodies of water, could hover around the freezing mark.
Here in Sault Ste. Marie, temperatures should reach the mid to high teens , though it could be a struggle with plenty of cloud and showers expected as the cooler air battles it out with the remaining warmth that early fall brings. Normal temperatures for the Sault sit in the low 20’s for this time of year. The cool down and wet spell won’t last for long however, milder air begins to build back into the area for the third week of September, just don’t expect days to reach above 22c.
