CTV News meteorologist Julie Atchison says a bit of fog Tuesday morning will clear, giving way to a mix of sun and cloud before increasing cloud cover in the afternoon. Temperatures are expected to reach 27 C, with the humidex making it feel like 31 C. Rain is expected to develop late Tuesday evening, with showers possible overnight and into Wednesday. Wednesday’s high is expected to reach 24 C, with rain likely in the morning before conditions become mainly cloudy in the afternoon, with a few breaks. Thursday and Friday are expected to bring sunshine and temperatures between 26 C and 27 C. “So this week a bit unsettled with the chance of showers moving in tonight and then some rain in the forecast followed by two beautiful sunny days,” Atchison said. Showers are expected over the weekend, followed by a cooldown Sunday and Monday, when daytime highs are expected to reach about 21 C.
