It’s the summer of extremes. After the storms, the heat wave hits Quebec. Forecast.
Mercury gets shaken
We are entering the third week of astronomical summer, and we continue in the extremes. After an episode of intense thunderstorms lasting a few days, oppressive heat will now dominate for the next two days.
Feelings of 40 or more
Apart from Bas-Saint-Laurent, Côte-Nord and Gaspésie, Quebec will see the mercury reach and even exceed the 30° mark on Wednesday. Humidity, which has caused all sorts of problems in recent days by fueling thunderstorms, is dragging its feet across the province. Result: feelings crossing the bar of 40 in the Montreal region as well as in the Outaouais. We will approach 40 in the Laurentians, in Estrie, in the Capitale-Nationale, as well as in Saguenay and Abitibi. Even around Chibougamau, the feeling will probably reach 35.
The air is saturated
The body evacuates heat mainly through perspiration. When the air is laden with humidity, it cannot accommodate the water vapor generated by the human body, so cooling is much more limited. It is therefore strongly recommended to avoid intense physical exertion on Wednesday and Thursday. From a feeling of 40, the degree of discomfort becomes overwhelming.
uncomfortable nights
This feeling also continues at night. The mercury will stay above 20° during the night from Wednesday to Thursday, as well as from Thursday to Friday in most areas of southern Quebec. The sun will give us the slip on Friday, but the humidity has no intention of leaving Quebec. The feeling will therefore remain quite uncomfortable. We are talking about 40 in Estrie, and more than 35 for the Montreal region, the Outaouais, the Capitale-Nationale and the Saguenay.
Moisture clings
This will be the first time this summer that the feeling will pass the 40 mark in Quebec. The average is 1.4 days to 40 or more in July. We could therefore exceed the average from the first week of the month. A cold front will move over Quebec starting Friday, and will lower the humidity slightly. But the rate will remain quite high, so the feeling will remain rather uncomfortable.
