Some brief freezing rain is possible today. Light precipitation is moving into portions of Southern Ontario this morning. The precipitation may initially begin as light freezing rain before temperatures quickly rise above the freezing mark. Over areas of higher terrain away from Lake Ontario including the Oak Ridges Moraine, temperatures may be slower to rise, remaining near or just below the freezing mark into the early afternoon. In these locations, the patchy freezing rain may persist into early afternoon. Slippery conditions are possible on untreated surfaces. Conditions will be monitored closely and freezing rain warnings will be issued if required.
