Weekend weather: great improvement for Heritage Days

Between a low pressure system which will evacuate towards central Europe and the strengthening of an anticyclone over Ireland, the weather will improve over the whole of France. But the northerly flow will cause a marked drop in temperatures, which will be below seasonal averages, especially in the morning. In this context, small early white frosts could appear at low altitude, even in the plains, in the countryside.

An improving weekend

Saturday, sunny spells will be generous in the west. North of the Seine to Rhône-Alpes, on the other hand, the sky will be more mixed and the risk of showers will be present towards the Belgian and German borders, in the cool. Near the Mediterranean, you will have clear weather under the effect of the sustained wind. Mistral and tramontane could reach 100 km/h while the westerly wind could reach the storm on the Corsican capes. A few isolated storms could also break out on the Nice Riviera.

Sunday, the conditions will change little, with the maintenance of sunny weather in the west and south and more cloudy in the east and north. In the Mediterranean, the mistral and the tramontane will have dropped significantly compared to the day before, blowing at around 70 km/h. From the Alpes-Maritimes to Corsica, sun and clouds will alternate but the risk of thunderstorms will disappear. The sun will be a little veiled in the west, but it is certainly on these regions that the weather promises to be the most pleasant, despite the good freshness of the morning.

Falling temperatures, risk of light frosts in the morning

With the direction of the wind to the North, temperatures will drop sharply compared to the week. It will be cool in the morning, between 5 and 14°C from north to south, with a possible risk of white frost in the north-west of the country in the countryside (Brittany, Normandy). In the afternoon, the maximum will generally range between 15°C near the English Channel and 25°C in the Mediterranean regions. These will be temperatures 1 to 3°C below average. You will have to think about taking the big sweaters out of the closet in the morning and relighting a few small fireplaces!
