May 29, 2012 — Tuesday will be another hot day in parts of Ontario. There is a chance isolated thunderstorms throughout the region through the afternoon and into the overnight hours.
It was feeling more like the middle of summer in some areas on Monday, and that heat will continue for parts of southern Ontario Tuesday.
Temperatures are set to climb to 30 degrees and with the humidity it could end up feeling like the mid-thirties.
As a result, a smog advisory remains in effect for parts of southwestern Ontario.
The heat and smog can reduce Air Quality levels and can lead to respiratory symptoms such as coughing or shortness of breath for those exercising heavily outside.
The Canadian Red Cross has the following tips to help you beat the heat:
Daytime heating combined with instability could also help to trigger thunderstorms throughout the afternoon and evening. The greatest threat with these storms will be large hail, damaging winds and intense lightning.
As the cold front moves through the region during the overnight, it will help to get rid of all that built up humidity. Cooler temperatures in the low twenties are expected on Wednesday.
On Monday, several communities broke their daily temperature records, including Hamilton, Windsor, Goderich and Collingwood.
Before 9:00 am Monday morning, Toronto declared a heat alert in anticipation of the hot temperatures.
Northern Ontario experienced cooler temperatures with scattered showers through the region. There were several storms along the Nickelbelt and rain in the northeast. This was a welcome relief to firefighters who've had their hands full with widespread wildfires.
