Rising temperatures and returning storms.
This new stormy sequence opens on Friday, due to a wind that topples “to the southeast sector bringing back to France the warmer air came from’North Africa”, explained the meteorologist Yann Amice
Temperatures will therefore rise after the freshness of the beginning of the week – caused by a polar flux and a north-northeast sector wind. But, but confronted with cold air at altitude and warm air in the lower layers, they will also be synonymous with storms.
“The instability will return, due to the presence of cold air at altitude that will slide once again by the west. New phenomena of convergence in low layers will be monitored with risks of heavy showers and hail in several regions during the weekend”
