Weekly weather: battle for air masses over France

While the cold endures all week in a small northern third of the country, where no thaw is expected in Lorraine, mildness returns from the southwest. This showdown between mild air and cold air will cause frequent rainy periods and snowfall in certain regions.

Breakdown to the south this Monday

This Monday, the weather is calm but cold over 3/4 of the country. In the south-west, a disturbance coming from Spain will bring rain south of the Garonne, moving towards the Mediterranean regions in the evening with the risk of relatively low-level snow over the southern Massif Central and Rhône-Alpes overnight from Monday to Tuesday.

On Tuesday, the weather is milder in the south

Tomorrow Tuesday, there will be many clouds. Rain will still occur in the morning in the southeast. Snow flakes are expected in Rhône-Alpes and Franche-Comté at low altitudes. In the afternoon, an Atlantic disturbance will bring some rain, which will turn to snow on contact with the cold air overnight.

Wednesday, a difficult day

In the southern part of the country it cried, with a rain/snow line around 1800 metres. It is therefore not good news for the Pyrenees, the Massif Central, where significant washout is expected. From Brittany to Grand-Est, regions located in the cold air, it will be able to reach the plains. These snow showers will also reach southern Normandy and the Paris basin. North of the Seine and Paris, heading up towards Hauts-de-France, the weather should remain dry, but the cold will still be just as significant.

Thursday more rain in the south, dry cold in the north and risk of snow in the middle

The situation should not change much from Wednesday, with the risk of snow from Brittany to Grand-Est, rain and mildness to the south and dry but very cold weather north of Paris.

On Friday, the cold will advance again in the south

The disturbance that ripples over France on Tuesday is expected to be dispelled by cold, dry air from Germany and Belgium. Consequently, this disturbance will be rejected to the south, from the Pyrenees to the Alps to the Mediterranean, as it will bring rain and snow above 1500 meters in the mountains. In the north, the dry cold will continue. Another day without thaw is likely in the Ardennes.
