Cornwall, Ontario, is in for a hot and humid week, with temperatures reaching 29°C and humidex values making it feel closer to 35, according to Environment Canada. No weather alerts are currently in effect for the area.
Monday will be sunny, becoming a mix of sun and cloud in the afternoon. The high is expected to hit 29°C, with a humidex of 35 and a very high UV index of 8. Winds will pick up from the northeast at 30 km/h later today.
The heat and humidity are expected to stick around through Tuesday, but things begin to shift on Wednesday. Environment Canada is calling for a 30 percent chance of showers on Wednesday with a high of 29°C. The chance of rain increases to 40 percent on Thursday, with a high of 28°C. By Friday, it drops back to 30 percent, and temperatures cool slightly to a high of 26°C.
These conditions follow a significant heat wave that hit much of Ontario over the Canada Day long weekend, when humidex values climbed into the 40s in many areas. For Cornwall, the current humidex of 35 falls into the “some discomfort” range, which means it is uncomfortable but not dangerous for most people. Heat warnings are typically only issued when the humidex reaches 40 or higher.
Residents are still advised to take precautions: drink plenty of water, stay in the shade during peak afternoon hours, and keep an eye on the forecast as conditions change mid-week. The weekend looks brighter, with sunny skies and a high of 26°C on Saturday; Sunday will see increasing cloudiness with a high of 26°C.
