Another mild day is expected across southern Ontario Tuesday, with temperatures reaching 14 C in London before cooler air moves in later this week, according to CTV News meteorologist Julie Atchison. The day will start with some cloud cover before breaking into a mix of sun and cloud. Temperatures could reach 16 C in Sarnia, while Huron-Perth and Grey-Bruce counties are expected to see highs between 11 C and 12 C. The chance of showers increases Wednesday, with a 40 per cent chance. Temperatures will cool to 7 C Thursday, with showers possible, followed by a mix of sun and cloud Friday. Atchison says overnight lows approaching the freezing mark could also bring a chance of snow mixing with rain. “If we get into some action at night, we will likely see some flakes mixing in early next week,” she said. A mix of sun and cloud is expected early next week, with a high of 9 C.
