A prolonged period of hot weather continues today and tonight. Cooler temperatures are forecast for the weekend. Daytime high temperatures in excess of 30 degrees Celsius, with humidex values in the high thirties to low forties, are expected today. Overnight lows near 20 degrees Celsius are also expected tonight. However, a cooler airmass moves into the area for Saturday and Sunday with daytime temperatures below 30 degrees both days. Please refer to your public forecast for further details on expected temperatures. Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category. ### Extreme heat affects everyone. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors. Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions. Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.
