The anticyclone Zèfiro tries to bring Summer, but this May 2023 will continue to alternate lightening and widespread instability.
Lorenzo Tedici, meteorologist of the www.iLMeteo.it site, confirms the expansion of the anticyclone Zèfiro, a wedge of the Azores Anticyclone that reaches Italy passing through Northern Spain, France, Switzerland and Germany.
Given the origin from areas north of the Alps, the sun will prevail in the Po Valley, while frequent thunderstorms will persist in the central-southern regions, especially close to the mountains and during the hottest hours.
In general, the weather will be characterized by a prevalence of sunshine, but in the afternoon thunderstorms will break out at times even intense on the mountains and locally towards the Tyrrhenian sector.
Wednesday 24 May will see a Swedish threat descend southwards: rain is expected from Scandinavia towards Germany and then towards the Alpine regions; later this disturbance will bend towards France, but could bring heavy rain and thunderstorms on the northern regions until Thursday: it is a forecast to be confirmed, but at the moment, after a very short quieter phase, some bad weather could also return to the North. temperatures will be warm in the North and in Tuscany, in line with the averages of the period elsewhere.
On Friday the weather will remain a bit uncertain especially in the afternoon with showers, then over the weekend the Swedish disturbance will reach Spain definitively abandoning Italy: on our country the weather will return a little more serene albeit in a context of widespread residual instability, with some patchy downpours throughout the boot and with slightly falling temperatures, locally below the average for the period.
