– a risk of heavy thunderstorms between the Hautes-Alpes, Provence and the hinterland of Nice. There is a risk that these thunderstorms will spill over onto the Côte-d’Azur in the afternoon.

– the lifting of a cool north-easterly wind of 40 to 50 km / h gusting during the day over the northern half.

Most of the country is under the influence of a powerful anticyclone present over northern Europe and generating a north-eastern continental flow over France. The pressures are lower towards the south-east, but instability is developing in the PACA region and Corsica.

From Brittany and Normandy to Pays de la Loire, you have to count on a few banks of mist or low clouds in places in the morning, but in the afternoon beautiful clearings develop. The northeast wind is sensitive with gusts of 40 to 50 km / h. Temperatures are between 11 and 15 ° C at dawn and highs between 20 and 25 ° C in the afternoon.

From Center-Val de Loire and Ile-de-France to Hauts-de-France, it’s a beautiful day ahead. After the mists and low clouds have dissipated, the sun is very dominant and the day takes on the appearance of summer. It is nevertheless necessary to count on a sensitive north-easterly wind which limits a little the rise in temperatures. Count between 10 and 15 ° C in the morning and between 21 and 26 ° C in the afternoon.

In Grand Est, Bourgogne-Franche-Comté and Auvergne-Rhône-Alpes, patches of grayness can be observed in the morning which dissipate slowly, then and the sun alternates with some cloudy developments during the day. The impression of good weather prevails with a moderate north to northeast wind. Temperatures are between 10 and 17 ° C in the morning and between 22 and 28 ° C in the afternoon, from Lorraine to the alpine valleys.

Between PACA and Corsica, the weather is becoming more unstable. After generally calm weather in the morning, the clouds quickly bud in the afternoon in the land as well as in the mountains and give stormy showers between the Alps, Provence and the Corsican mountains. In this context, we cannot exclude the onset of heavy downpours in less than an hour as well as hailstorms. Temperatures are between 16 and 22 ° C in the morning and between 26 and 31 ° C in the afternoon.

The air is unstable this #Tuesday in the south-east and #thunderstorms are already breaking out this morning in the Alpes-de-Haute-Provence. ⚠ Be careful, this afternoon, #thunderstorms will multiply and sometimes be strong over all the Alpes-du-Sud, with up to 50 mm locally. ⛈ pic.twitter.com/KTzIqLviwE

From Nouvelle-Aquitaine to Occitanie, the good weather persists with generous sunshine and afternoon heat. Unstable clouds form over the Pyrenees and can locally give a shower or a thunderstorm in the afternoon or evening. Temperatures are between 15 and 21 ° C in the morning and between 25 and 31 ° C in the afternoon.

The current weather configuration will be blocked over Europe until the end of August, or even possibly until the week of the start of the school year. This situation will bring lasting bad weather to the countries of Central Europe, while the weather will be milder over Western Europe, and therefore France, despite shades of gray and temperatures. Explanation on the causes and consequences of this development, and especially on the type of weather you can expect in our country.

Every Thursday, the 4-week weather trend is updated. The latter, which covers the end of the summer vacation and the start of the school year, presents the most likely weather scenario for the next four weeks until September 19.

For your last weekend, which also corresponds to the last weekend of school holidays and the meteorological summer, the weather promises to be contrasted depending on the region with temperatures below the seasonal averages in the northern half. But there is no inclement weather in sight, which is good news.
