It will snow in the morning in Hauts-de-France, Haute-Normandie, the Paris region, the east of the Centre-Val de Loire, Burgundy, Limousin and in Auvergne-Rhône-Alpes. During the afternoon, the snow will temporarily stop in the north of the country, replaced by rain.
On the other hand, the snowfall will persist and will increase in the afternoon on the Massif Central and the Alps. The snow may temporarily bleach the ground in the plain and from 300 m the accumulations may reach 2 to 5 cm, locally 5 to 10 cm. On the Massif Central, the Jura and the north of the Alps, 10 to 20 cm of snow are expected from 600/700 m.
Over the Grand Est, the sky will be overcast, but snowfall will be scattered. This winter weather will be accentuated by the north wind. To the west, from Brittany to Aquitaine, the sky will be variable. Over the Pyrenees, the sky will remain cloudy and it will snow intermittently at low altitude and above 800 m we expect 10 to 20 cm. In the Mediterranean regions, the weather will generally be dry, but the tramontana and the mistral will be strong, locally exceeding 100 km/h. On the Isle of Beauty, a strong westerly wind will accompany showers. In the following evening and night, the return snowfall will be reactivated.
Temperatures will be low, with minimums most often between -2 and 2 degrees from north to south, 4 to 8 degrees on the Atlantic coast and around the Mediterranean. The maximum will also drop sharply with 3 to 7 degrees on the eastern half, 6 to 10 degrees in the west, another 10 to 17 on the Côte d’Azur and Corsica.
