Rain is expected to turn to snow from Thursday to Friday in parts of northeastern Quebec, which borders Labrador. Only a few communities, such as Fermont and Schefferville, Que., are expected to be affected. Up to 15 cm could accumulate by the time the system leaves. Visit our Complete Guide to Fall 2022 for an in-depth look at Fall Forecasts, tips to plan for it, and more! Although September snowfall may be unusual for some areas in Canada, it is normal for the aforementioned region to occur at this time of year. However, it should be noted that maximum temperatures are still above the freezing point and will rise again early next week. Therefore, snow is not likely to stick to the ground. This transition to snow is the result of a descent of cold, northerly air on the trailing edge of the system. Even without the snow, Ontario, Quebec and Atlantic Canada won’t be spared a taste of cooler fall weather. Descent of cold air will cause temperatures to drop Wednesday through Thursday. Temperatures of 9°C below normal are forecast in parts of Quebec, while Toronto, Ont., struggles to reach the upper teens and New Brunswick is in the low teens for the first time since June 19 — more than 80 days ago . With the cold temperatures comes the risk of frost in several areas of Quebec and parts of central Ontario. The new air mass may bring gusty winds Wednesday and Thursday to Ontario and Quebec, reaching 50-80 km/h along the border. But the good news is that the lull will be short-lived as summer weather returns for the weekend to Central Canada. Sense-like values ​​in Toronto will be in the 30s.
