A heat warning remains in effect on Saturday (July 6) for most of the Kawarthas, including Peterborough, Kawartha Lakes, Hastings, and Northumberland.
A hot and humid air mass is expected to remain in place, with temperatures near 30° C with humidex values in the upper 30°s to 40° C.
With the passage of a cold front on Saturday evening, cooler temperatures and lower humidity is expected for the remainder of the weekend.
As the cold front moves in, there is a risk of a thunderstorm.
Environment Canada issues heat warnings when very high temperatures or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.
Drink plenty of water even before you feel thirsty, stay in a cool place, and never leave people or pets inside a parked vehicle.
