Forecast Discussion

Temperatures are expected to drop to near the freezing mark throughout much of Southern Ontario during the morning on Sunday. This will bring the risk of frost to all areas away from the shorelines of Lake Ontario, Erie, Huron and Georgian Bay. Be sure to protect any sensitive plants that you want to save. The frost will melt away later in the morning after the sunrise.
