Are these the first flakes of winter which will fall on the French plains?
Five days before the phenomenon, it is too early to say with certainty. However, this Saturday, November 16, 2024, Yann Amice, meteorologist for Weather & Co, confirms actu.fr that the context is “favorable” for the first snowfall.
The meteorologist invites us to pay particular attention to the day of Thursday November 21Or
the first snowflakes (and rain) could even appear in northern Brittany and Normandy.
The context
This weekend will be anticyclonic with few disturbances in the country. But from Monday, “a depression is settling over Ireland”, describes Yann Amice, who brushes aside the forecasts which may have spoken of a “storm”.
This depression will lead a disturbance over the northern half of the country.
This disturbance will sink, slide, throughout France during the night from Monday to Tuesday and will still bring windmuch less precipitation than what the country has experienced in recent weeks.
This precipitation mainly concerns Normandy, the Massif Central, Alsace and Hauts-de-France, even if “a large northern half of the country will be affected”, notes Yann Amice.
Rain then, no snow yet. Due to the fairly “mild” temperatures (but still cold for a week) brought by the southwest flow.
But from Wednesday, the flow will shift from southwest to northwest, with “much colder air at altitude and at the surface.”
“A favorable context”
From Wednesday therefore, the temperatures will dropquite clearly. This will be particularly felt from Thursday morning, when it could snow locally.
In the northeast quarter, the minimums will be included between -1 and 2 degrees. But this part of the country is not the only one where you will have to take out the hats.
Between northern Brittany and Normandy, the minimums will be between 1 and 3 degrees.
“We must be wary of the day of November 21,” predicts Yann Amice who evokes “a very favorable context”, particularly around Lyon, the center of France, and obviously on the massifs (Massif central and the Alps).
Because at the same time, the rainy clouds linked to the disturbance at the start of the week will slide over France with risks of precipitation.
Precipitation will continue to move towards the south-east of France, causing rain or snow as this cold air settles over the country
Where could it snow?
Faced with this observation of precipitation and low temperatures (with a falling rain/snow limit): yes, it could snow. From Wednesday, northeast of Paris, with “snow mixed with rain”, notes the meteorologist.
Where precisely? It is still a little early to say it exactly, but the meteorologist estimates that there is a good chance that the outskirts of Lyonincluding in the plains, is concerned.
The central Franceand the northeast quarter should also have the right to their flakes. If we still have to be careful, it is also possible that there will be a little snow mixed with rain around “Rennes, and going back towards Normandy”, indicates, taking all precautions uses, Yann Amice.
The maritime borders will be sheltered from snowflakes.
All these areas mentioned are also subject to the black ice. Necessarily. Vigilance will therefore be required in the event of temperatures near 0°C and precipitation: especially if you take the road.
Yann Amice specifies: “This episode will be very punctual. » And the redoux is already announced for the weekend of November 23-24.
