London is seeing seasonal temperatures heading into the holiday weekend, in the mid to upper teens. CTV Meteorologist Gary Archibald says weather is fair into the evening, but it will change overnight. “This massive system of low pressures lingering across northern parts of Ontario into eastern Ontario and parts of the Bruce Peninsula, as well as the Georgian Bay shores and the eastern shores of Lake Huron have seen some scattered showers,” he said. “It’s been light, the worst of it is well to our north, working east and so that bodes well for the most part across southern Ontario proper. The next 12 to 18 hours, we’re not likely to see a lot of active weather.” Here’s a full look at your forecast: Thursday night: Partly cloudy with a 30 per cent chance of showers, becoming clear overnight.
