Attention, snow to come!
Météo France is planning the “first winter episode of the season” this weekend.
"Several disturbances will cross the country, in a north-westerly flow," warns the meteorological institute.
In some areas, several inches of snow could fall.
At the same time, the massifs will benefit from (very) good snow cover.
"From this Friday evening, the disturbance extends (ra) from the regions of New Aquitaine to the North-East and is accompanied (ra) by moderate or even marked precipitation," writes Météo France.
The rain from the southwest will turn into snow as it goes up "around the Massif Central and on the plains between Burgundy and Lorraine".
There could be 1 to 3 cm of snow, even 5 in places, on the plains of the Grand-Est.

Saturday, a disturbance from the English Channel will bring "rather scattered showers, sometimes stormy and more numerous near the north and southwest coasts", describes Météo France.
They will “sometimes be carriers of showers, rain and snow mixed in the northern half or even snow”.
In the Grand-Est, again, and Hauts-de-France, 3 to 5 cm of powder could fall.
Just enough snow to "temporarily" bleach the soil could fall overnight from Saturday to Sunday over much of the north of the country.
Sunday, a new disturbance could be responsible for showers or snow in the plains in the plains of the north-eastern quarter of the country and around the Alps.
Cold and snow on the mountains
Without being able to be considered as "a cold wave", this weekend will give "the glimpse of a winter atmosphere", warns Météo France. In most areas of the northern half, 0 ° C will be close if not reached on Saturday or Sunday. In the afternoon, notes the meteorological body, "only the Mediterranean should exceed the 10 ° C mark while the northeast will struggle to rise above 3 ° C".
The situation this weekend should be favorable to the snow cover of the massifs, a few weeks before the Christmas holidays. On the massifs of the East, one will be able to observe flakes from 300 m of altitude. "In the Northern Alps, the accumulations over the whole of the episode may exceed 10 cm on the first altitudes and reach several tens of centimeters above 1000 m in altitude", just like on the Jura massif ( with up to 40 cm in places), beyond 400-500 meters, specifies Météo France. The southern Vosges, which should be supplied on Saturday evening, will be able to receive up to 20 cm from an altitude of 800 m.
"On the side of the Massif Central, it is from an altitude of 800 m that the snow should hold, with accumulations on average between 10 and 20 cm locally 30 cm on the flanks exposed west", continues Météo France.
A good western half of the Pyrenees should also be well supplied with a rain-snow limit sometimes close to 800 m during the nights.
Along the Pyrenean massif from an altitude of 1,200 m, the accumulations may range from 50 cm to locally 1 m on the side of the Basque mountain.
