A mix of sun and cloud is expected across the region tomorrow. Temperatures will be warmer than today, however humidity will remain fairly low still, meaning humidex values are not expected.
The start of the heat wave will be tomorrow, before the region sees much hotter conditions on Monday. We are expecting humidex values to be between 40 and 45°C across much of the region on Monday, with Eastern and Central Ontario seeing humidex values between 35 and 40°C.

Ensure you stay hydrated and limit time outdoors during this heat wave. Extreme heat can be dangerous, especially to children, pets, and the elderly.
