Overall situation
Pressure measured in Aosta at 7 am: 1023 hPa
Il promontorio anticiclonico, che dall'Africa del nord si estende fin sull'Europa centrale, tende ad indebolirsi permettendo l'ingresso di correnti atlantiche più umide e instabili favorite da una circolazione depressionaria attualmente centrata nei pressi delle Isole Britanniche. Ne conseguirà un fine settimana all'insegna dell'instabilità che potrà favorire rovesci e temporali locali che potranno seguire a condizioni ben più soleggiate. Da lunedì invece l'Europa sarà influenzata da un vasta campo anticiclonico che riporterà maggior stabilità.
