Environment Canada says, “Rain, heavy at times, is forecast to begin this evening. With temperatures hovering just above the freezing mark, a brief period of freezing rain is possible. However, temperatures will slowly rise tonight ensuring only rain by Thursday morning. Rainfall amounts in the 20 to 30 mm range are expected by the time the rain transitions to snow Thursday night.
