To the change of weather next week

TO Regis CREPE, meteorologist

After an atypical March in France, when rainy weather touched the extreme south of the country, the weather is about to change in April. This change should start next week, first of all, with a rapid deterioration. Here’s the weather scenario for today.

This month of March will be atypical, as expected seasonal forecast from the Weather Channel on February 10. While maintaining a powerful anticyclone over Northern Europe, Atlantic disturbances could not circulate over our country. On the whole, France has so far enjoyed mostly good weather, with the exception of the far south, where in the Languedoc-Roussillon the rains have been surprisingly abundant. This good weather has more than just benefits : exacerbates drought in many regions, leads to poor air quality and contributes to night frosts that are detrimental to fruit trees.

Cold weather next week

In recent years, early spring has been fairly similar, with March often sunny and mild. Last year, at the end of March 2021, a real heat season, breaking many records. This time temperatures won’t reach the same level at all, far from it, but the values ​​remain 3-4°C above average until this weekend. On the other hand, clear nights contribute to nocturnal radiation and frost, which is detrimental to fruit trees. At the same time, March frosts are not uncommon, and it is still impossible to talk about “late frosts”. What is harmful is the advance of vegetation due to early sweetness.

These temperatures could drop sharply in the first half of next week north of the Loire with the arrival of polar air through the British Isles. This change in air mass will remain dry in the north of France, but will reactivate instability in the south of our country.

Heading into a stormy wave in the south of France?

The air mass conflict that will occur over France could cause severe instability in the south of our country from Tuesday to next Thursday, although this development has yet to be clarified. The storms then coming from Spain will break out between the Pyrenees and the Alps, including the PACA region and Corsica. These last two regions are driest in France Currently. Therefore, rains are welcome before the beginning of April, which should be dry there. But storms, sometimes strong and potentially accompanied by hail, will break out locally and probably not flood all these zones. On the other hand, it is also possible that these storms take place at sea, only along the Mediterranean coast. This will be indicated in our next updates.

Beginning of longer changes in April?

This weather transition may herald a more global weather change in April. Indeed, in the first ten days, unrest from the Atlantic may return, bringing rain to the northern part of our country. April may then return to normal rainfall in these regions. On the other hand, the southern third may return to more normal weather, that is, dry and sunny again, after the disturbed brackets of this month of March. In short, we are bringing French weather back in April after an atypical March.
