It'll be another hot, humid weekend in the region, but temperatures are expected to drop soon with the arrival of a cold front.
A heat warning remains in effect for Chatham-Kent and Windsor-Essex.
Humidex values are expected to reach 40c this weekend, as a hot and humid air mass stays put over the American Mid-West. Afternoon temperatures will be in the low thirties.
Environment Canada says the daytime high on Saturday may be slightly below warning criteria in some areas due to cloud cover and a chance of showers. Overnight lows will remain in the low twenties, providing little relief from the heat.
A cold front is forecasted to move through the area Monday night, bringing in a cooler and less humid air mass.
The weather agency recommends that people drink plenty of water and seek a cool place. People or pets shouldn't be left inside a parked vehicle.
