Maximum attention is paid to the weather evolution of the week, with the arrival of the African anticyclone that could get really serious starting next weekend. The big rollover will see a hot air mass, of direct Saharan extraction, pointing at Italy.
Before that, fresh and unstable air flows will continue to touch Italy favoring showers and storms especially in the Center-North. This situation will persist until Thursday or Friday. There will be locally intense phenomena, also accompanied by hail.
The latest model launches confirmed this turning point, which will take place from Friday, July 7, beginning to involve Sardinia and Sicily more, and to a lesser extent the peninsular areas. This will be the prelude to a weekend with heat everywhere in accentuation.
The reinforcement of the African anticyclone over the weekend it will bring the mercury to peaks of 40-41 degrees in inland areas of Sardinia. Throughout the Peninsula the values will be more contained, with peaks of 35-37 degrees in the hinterland of the central regions of the Tyrrhenian and in some areas of the South.
Naturally, the overwhelming power of the anticyclone will guarantee almost indisputable stability, in the face of so much heat. Only the Alps could be marginally affected by some unstable disturbance. of little importance with storms of a fairly isolated nature.
The return of the subtropical anticyclone will materialize after the collapse of the North European depression in the Atlantic. there is the risk of being generated with a fairly blocked configuration, with a hot flow directed towards Italy for several days.
This is the second major heat wave of the summer of 2023. Unlike the previous heat wave that occurred around the summer solstice, this time the heat risks being very persistent, especially in the Center-South. Even the intensity could be extraordinary, with peaks of 43-45 degrees in the South and in the Islands.
There is a risk that the extreme heat wave will last beyond two or three canonical days and last even a week. The American Weather Center identifies the stoppage of the great heat only around July 15 and 16, but it could turn out to be only a partial attenuation. Naturally, these are projections to be taken with a grain of salt.
