Environment and Climate Change Canada reports that inland areas will reach 28°C on Monday and 29°C on Tuesday.

Humidex and Heat Safety
“It’s not really temperature, per se, but it’s more of how it might feel,” said Bobby Sekhon, a meteorologist with Environment and Climate Change Canada.
“Of course, that takes into account the temperature and the amount of moisture in the air.”
The agency noted online that the humidex reading can help people make informed decisions about outdoor activities and heat-related health risks.

“Right now, there’s a high-pressure system keeping things pretty warm and consistently clear, with a temperature increase in the next few days,” explained Chloe Katsademas, also a meteorologist with Environment and Climate Change Canada.
Clear skies will give way to precipitation as the high-pressure system moves out later in the week. “Later in the week, there’s a trough approaching from the Pacific.
At the end of the week, into the weekend, there will be precipitation,” Katsademas added.
Showers and periods of rain are forecast for Friday and Saturday. Daytime highs will drop to 15°C, with overnight lows reaching 10°C on both days.
