Locally stormy showers may bud between Brittany, Pays de la Loire, Charente and the Basque Country this Wednesday. The sky will also become more changeable over the Pyrenees and the Alps, or even the Jura, and a new, more marked stormy salvo is also expected over the Aquitaine Basin from the evening.
In the rest of the country, the weather will be drier, still very sunny near the northern borders, bright or even sunny elsewhere despite a sometimes dense veil of clouds.
Quite strong wind in many regions
The wind will become noticeable in many regions, from the east to the northeast in the northern half with gusts of up to 60 to 70 km/h near the English Channel, from the southeast to the south, with a autan wind strengthening to 70 km/h.
Except in the northwest, with this wind, the weather configuration this Wednesday will be conducive to a further rise in temperatures, which will sometimes increase by two to four degrees, or even more, compared to this Tuesday. Peaks of more than 25 °C are forecast in the north as in the south (25 °C in Paris, Tours, Lyon, Clermont-Ferrand, Agen, Ajaccio and Le Havre for example).
And it will be up to 26 to 28 °C in the Center and Poitou-Charentes. A mildness which will therefore continue at the end of the week, but in instability.
