4-week trend: weather from September 12 to October 9 – The Weather Channel

Stormy rainfall often circulated randomly over the country. Some regions benefited from significant accumulations of rain with the passage of showers and thunderstorms while some sectors passed through thunderstorms or rains. In general, there is an improvement in terms of surface dryness but this does not solve the problem of groundwater which does not benefit from these rains which benefit nature or run off towards the watercourses. This explains the maintenance of the very many water restrictions in place since this summer. Credit: La Chaîne Météo Credit: La Chaîne Météo Week from 12 to 18 September: strong heat stroke followed by thunderstorms Under the effect of the remnants of Hurricane Danielle which will circulate off the Iberian Peninsula, of subtropical origin will move up in France bringing a peak of strong heat at the start of the week with temperatures 5 to 8°C higher than normal for the season. We could even approach the heat records in the southwest. From Monday evening or Tuesday, a stormy degradation will occur from the south and the storms will move up to the north and northeast. We will monitor a possible strong stormy degradation in the middle of the week in the Mediterranean. After the stormy degradation, temperatures will drop a few degrees but will remain above normal for the season. Week of September 19 to 25: improvement from the north, unstable in the south This week could see the return of drier weather from the north under the effect of high pressure from the British Isles to Scandinavia. In the south, the pressures would remain lower and the weather more unstable with the persistence of stormy showers. Temperatures would generally remain a little above normal for the season. Week of September 26 to October 2: fine late-season weather, stormy in the southeast The end of the month and the beginning of October could be stormy in the southeast, with particular monitoring of the Mediterranean regions, while milder weather dryness would continue over our western and northern regions. This evolution must be taken as a probability at this time, especially in a context where the centers of action will be very changing. Week of October 2 to 9: possible return of disturbances in the north with cooler weather A west to northwest oceanic regime could set in over the northern half with disturbed passages and progressively cooler weather. Southern regions would benefit from drier and sunnier conditions, especially near the Mediterranean. This trend still requires confirmation. In conclusion, this month of September will have made it possible to find more changeable and unstable conditions after a summer that was too hot and too dry. It will take a late fall and a well-watered winter to really overcome the drought.
