A depression will cross our country directly on Thursday, bringing a turbulent meteorological cocktail: heavy rain, stormy winds, and possibly snow all the way to the plains.
Snow in the plains: a very delicate forecast

72 hours before the event, several scenarios remain possible due to uncertainty over the exact positioning of the center of the depression. However, the majority scenario predicts a snowy episode that could reach the central-eastern plains, in particular. From the end of the night from Wednesday to Thursday and until midday, snow could appear in regions such as Burgundy and the north of Auvergne-Rhône-Alpes. Early in the morning, flakes could also be observed from Brittany to Center-Val de Loire, although this snow is unlikely to stick to the ground.
The situation is particularly complex due to a conflict of air masses: mild air coming from the Atlantic and cold air coming from Northern Europe. A difference of a few dozen kilometers will be enough to switch between rain and snow. Finally, a mild spell is expected on Monday afternoon, but its exact extension still remains uncertain.

South of the depression, strong winds are expected from the Atlantic coast to the Mediterranean.
Atlantic coast : The west-southwest wind will blow like a storm over New Aquitaine, with gusts of up to 120 km/h. This wind will be accompanied by waves of 5 to 6 meters, posing a risk of submersion, although the tidal coefficients are low.
In the lands : Gusts will generally be between 70 and 90 km/h, but will exceed 110 km/h on the peaks of the Massif Central.
Mediterranean : In the evening, the tramontane and the westerly wind will strengthen, increasing the risks in this region.
The weekend promises to be very hectic, with a forecast that will still require adjustments in the next 48 hours. However, this cold snap should quickly give way to a marked mild spell from the weekend, with the arrival of significantly milder air.
