Much of eastern Canada remains under blanket of hot, humid air


A high of 26 and low of 14 is expected in Toronto on Friday, Ms. Hobelman said, with a chance of showers and a thunderstorm. The heat is going to continue until Thursday, with some relief on Friday when temperatures finally start dipping under 30 C.

The cool down will be short lived, as heat and humidity will return on Tuesday and persist through most of this week.

"A cold front will usher in a slightly cooler air mass for (Monday)".

Overnight low temperatures are expected to be in the low 20s, with some rural areas dipping into the low teens - but no matter where you are in southwestern Ontario, there won't be much - if any - relief from the heat. Daytime temperatures will again be near 30 degrees, with humidex values in the mid 30s.

Meanwhile, the the Middlesex-London Health Unit (MLHU) has prolonged their extended heat warning.

It says "a very warm and humid airmass" will settle over eastern Quebec and the Maritime provinces this weekend, and will last into next week.

"This will be the most significant heat event in the past few years", according to Environment Canada. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.

There are many warning signs for heat illness, including swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

The City of Toronto continues to have seven cooling stations open across the city as well as public, air-conditioned spaces like libraries and community centres available so people can catch a break from the never ending heat wave.
