There’s lots of sunshine through southern Ontario, despite temperatures cooling slightly Tuesday. CTV Meteorologist Julie Atchison says temperatures are in the low to mid-teens, between 9 and 11 C throughout Huron-Perth and Grey-Bruce and are expected to rise a couple of degrees throughout the afternoon. “High pressure will continue to drift into south and central Quebec and I’m tracking a warm front that will arrive as we head into tomorrow,” Atchison said. “That means a push of warmth across the area and overnight temperatures are set to climb. So, some nice warm air moving in for your Wednesday.” Overnight, temperatures will fall to 7 C. Here’s a full look at your forecast: Tuesday night: Partly cloudy. Low 7 C. Wednesday: A mix of sun and cloud. High 18 C. Wednesday night: Clear. Low 9 C. Thursday: A mix of sun and cloud with a 30 per cent chance of showers. High 20 C. Friday: Sunny. High 16 C.
