Update May 5, 2024 at 11:00 p.m.
If the forecasts for the coming days are enough to put a smile on your face, a change of diet in the middle of the week will cause the thermometer to lose many feathers.
In short :
Context
The first days of the week look set to be magnificent: highs will be above 20°C for southern Quebec and the sky will be generally clear.
Perfect conditions to welcome the solar summer season. The metropolis could even receive up to 11 hours of sunshine on Tuesday.
Good to know: the town of Mont-Joli crossed the 20°C mark for the first time this year on Sunday. The day before, the mercury reached 23.6°C in Gatineau and 23.0°C in Témiscaming.
However, a change of regime will subsequently confuse the issue. From Wednesday, a descent of cold air will cause the mercury to drop and prevent highs from reaching seasonal norms from May 8.

Quite a contrast is emerging on the horizon. If several regions of Quebec recorded their highest maximum of the year during the weekend, a harsh setback will spoil the party in the middle of the week.
The trough that is coming to Quebec on Wednesday is of good magnitude. According to Bertin Ossonon, meteorologist, “the passage of a front in northern Quebec on the weekend will open the door to cold and the return of snow at the start of the week in these regions”.
Even if this descent of arctic air will not cause the mercury to drop to the point where we see a white carpet again, the average temperatures will still be around 4°C below seasonal norms from May 9 to 14. At its coolest, a maximum of 12°C is expected on May 11 in Montreal. Remember that the average for the city of a hundred bell towers is 18°C at this time of year.
