The Azores anticyclone is temporarily influencing the weather in Italy, guaranteeing good weather conditions for two days before the arrival of a disturbance from the North Atlantic.
Introduction
The Azores anticyclone offers two days of stability, but from Wednesday 16 September a North Atlantic disturbance will sweep away the mildness, resulting in storms and a temperature collapse starting from the northern regions. In detail, the start of the week opens with sunshine across a large part of the country thanks to the temporary influence of the Azores anticyclone. Between Monday 14 and Tuesday 15 September, Italy will benefit from clear or slightly cloudy skies and a pleasant climate, except for some isolated uncertainty in the North-East, on the Adriatic side and in Sicily, the latter touched by a cyclonic vortex headed towards Greece. However, it will only be a brief interlude: the high pressure will remain confined to the open ocean, leaving the peninsula totally uncovered and vulnerable to the unstable currents of the North Atlantic.
