Ontario: Humidex values could approach 40, heat warnings issued

TEMPERATURES SOAR WEDNESDAY, ANOTHER STORM RISK
The risk for more rain and thunderstorms returns to the region Wednesday night after soaring temperatures could top 30°C throughout the day. Heat warnings are currently in place for southwestern Ontario, where humidex values could approach 40 on both Tuesday and Wednesday as a hot and humid air mass from the southern U.S. surges into the region.
"We'll see a sharp temperature divide across the province on Wednesday," says Weather Network meteorologist Kelly Sonnenburg. "We've got temperatures climbing towards the high 20s and low 30s, especially across parts of southwestern Ontario, while it will be a struggle to even climb above 10°C for areas north of cottage country.
