Clouds & Showers

This update will be brief this morning. A closed off low pressure area over the Great Lakes is finally shifting east over Quebec today. That means our sunny and warm weather has come to an end. Look for lots of clouds and showers today and well into this upcoming weekend. Some showers may become heavy and there is even the risk of thunderstorms. Locally rainfall amounts could exceed 25mm (1 inch). Temperatures will be mild again today, well above normal at 23C but then cooler weather will move in as a northwest flow develops on the back side of this stubborn low pressure. By the weekend a steady rain is likely with temperatures no better than 10 or 12C during the day and as chilly as 3 or 4C at night. Frost is possible in Ontario this weekend and in Quebec early next week,
