An intense heat wave is preparing: see when

In short: – Intense heat wave preparing: see

• Possible return of 30 ° C. Nevertheless, more from Friday in southern Quebec;

• Up to 8-9 consecutive days of heat above normal;

• Humidex from 40 and more possible from Sunday to Tuesday;

• Risks of bonus thunderstorms.

High possibility of heat wave – Intense heat wave preparing: see

According to the most recent forecasts. Similarly, a prolonged sequence of days at 30 ° C and more awaits several regions, particularly the southwest of the province, between Gatineau and Montreal.

A heat wave is very possible, at least three consecutive days intense heat wave preparing: see exceeding the threshold of 30 ° C. Some meteorological models go further, evoking eight to nine consecutive days of temperatures that oscillate around this threshold.

Also at the rendezvous: humidity

Humidity could play an important – and unpleasant – role – in this heat wave. This one. which goes back from the Gulf of Mexico, will increase the dew points around 15 to 20 ° C from Friday, which will make the atmosphere particularly suffocating, even during the nights.

Between Sunday and Tuesday, it would not be surprising that the Humidex index exceeds 40, which would place the heat felt in an area of great discomfort where it is recommended to avoid great physical efforts.

Finally. this cocktail of heat and humidity could also promote intense heat wave preparing: see the formation of violent thunderstorms, phenomena that can generate significant rains, heavy gusts and hail.
