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.

More severe storms are expected west of Toronto and all the way into Quebec

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:

  • Drink lots of cool water even before you feel thirsty
  • Go to air conditioned places, including shopping malls or one of many local libraries or community centres
  • Take cool showers or baths or use cool wet towels to cool down 
  • Wear loose light coloured breathable clothing and when outdoors wear a wide-brimmed hat 
  • Avoid the sun and stay in the shade or use an umbrella 
  • Reschedule or plan outdoor activities during the cooler parts of the day 
  • Never leave seniors, children or pets unattended in a car

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. 

Borden was the hot spot of the country at 34.7C.  

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
