This Wednesday begins with many cloudssometimes accompanied by “some light rain or drizzle”“from Brittany and the north of New Aquitaine to the northern borders”, summarizes Météo France.
Due to a disturbed ocean currentthe northern half will also experience wind, especially the North-West, adds the specialized site meteo-villes.com. Which will also set the tone for the next day.
A very active cold front with sustained rains, strong winds and a significant drop in temperatures will sweep across France from the North-West to the South-East during the day on Thursday.
The gusts, coming from a southwest wind, could be quite sustained. Météo France forecasts: “between 50 and 60 km/h inland, between 60 and 80 km/h on the Channel coast, then up to 60 to 80 km/h the following night from Brittany and Normandy to Flanders, or even 90 to 100 km/h on the coast of Pas-de-Calais.”
A calm morning in the southern half
The southern half, on the other hand, will benefit better weather this Wednesday. Météo France evokes a calm morning despite a sometimes cloudy sky.
Gray weather may appear in the afternoon, but “it is limited to the Côte d’Azur and Corsica” while “the sun is more generous from the southwest to the southern Alps”, continues the national meteorological institute.
Mild temperatures
This mildness will be particularly visible in terms of temperatures, apart from some possible local frosts “from Aquitaine and Midi-Pyrénées to Rhône-Alpes and South Burgundy with 0 to 5°C, sometimes -1°C”.
We therefore expect between 10 and 15°C in the eastern half, between 12 and 17°C in the west and even locally up to 20°C “in the south of Aquitaine up to the Pyrenean foothills”, ends Météo. France.
The lull will be short-lived, since an anticyclone will return at the end of the week and “the weather will become more agitated again north of the Seine between Sunday and Monday with frequent rain”, concludes meteo-villes.com.
