The trends outlined in recent days are confirmed: the week which begins this Monday, November 18, 2024 will be synonymous cold, heavy rain, a few gusts of wind in the north of France… and also snow.

We are not only talking here about snowfall in mountain areas, but about the return of snowflakes at low altitude and even in the plain. The phenomenon should be monitored from this Wednesday, November 20, 2024 in part of France.

A cold depression corridor

This weekend, meteorologist Yann Amice indicated actu.fr that the context was “favorable” for the arrival of snow in France in the middle of the week, with “much colder air at altitude and on the surface”. And what are we saying this Monday?

“Wednesday will be quite cold and will welcome the first showers of snowbefore Thursday we will be able to have heavy snowfall »confirms to actu.fr meteorologist Guillaume Séchet. This is what emerges from the weather forecasts starting this Monday.

Indeed, after the departure of an anticyclone this weekend, “a cold low-pressure corridornative to the North Sea and Norway, has invaded the northern half of Europe” and arrives in France this Monday. Its arrival will cause a conflict of air masses with the milder air already present.

Consequence: this Monday there will be “some heavy rain in the far north of France,” continues the founder of the site meteo-villes.com. Before this corridor rushes towards the south of France and settles, during the night from Tuesday to Wednesday, in the northern half.

Where will it snow on Wednesday?

So much for context. On Wednesday, concretely, the snowflakes will mainly fall on Normandy. “Maybe also on Île-de-Francebut it will be very anecdotal and rare to note it,” estimates Guillaume Séchet.

However, “abundant” snowfall will affect the Alps on Wednesday morning. “From several tens of centimeters” to more than a meter, announce our journalistsnews Lyon.

Alpine ski resorts will therefore benefit from a first “good layer” of snow to kick off their season. The first to open are Chamonix, Val Thorens and Tignes, November 23rd. The seconds (including Val d'Isère, Alpe d'Huez and 2 Alpes) wait until November 30.

The bulk of the snow expected Thursday

The snowflakes will mainly concern the day of Thursday, November 21, 2024. Between the cold air which has settled in and the arrival of a new disturbance in France, “there could be snowfall in the regions where it will be very cold,” summarizes Guillaume Séchet.

The persistent cold and expected precipitation maintain a rain/snow limit between Brittany, Pays de la Loire, Center, Burgundy, Franche-Comté and the Rhône-Alpes zone.

The fact that the snow sticks to the ground, “it's also possible, provided it doesn't rain”, continues the meteorologist, insisting on the fact that it is “still too early to know where the precipitation will be the most strong and where the rain/snow line will be precisely located.

Scenarios indicate up to 5 cm of snow in the plains, but that seems frankly unlikely to me.

A few flakes on Friday, before the return of mild weather

After the return of snow on Wednesday and Thursday, it is back to calm on Friday. Well, almost. “The cold is taking over almost everywhere, but some snowfall will be possible in the north of France »concludes Guillaume Séchet.

So keep your big sweaters, scarves and hats close to you this week. They will be of less use to you after the weekend, the sweetness appearing due to a “powerful southerly current”.

Until then, cover up well!
