Two Atlantic perturbed fronts will cross Italy between Monday 9 and Friday 13 November, bringing widespread rain, snow in the Alps and Scirocco and Libeccio winds. Accumulations of up to 150 mm/24h expected in Liguria on Thursday 12th, with possible storm.

A temporary stable phase affects the Centre-North with light rain in the South, but from Monday 9 November the return of Atlantic disturbances will bring widespread rain, snow in the Alps and winds of up to 90 km/h, with the peak of instability on Thursday 12 November in the Centre-North.

A disturbed Atlantic front passes over Italy on Saturday 7 November with rain, snowfall on the mountains and winds of up to 50 km/h. Since Sunday 8th, high pressure has brought stability and calm to much of the territory, with night fogs in the North and in the central valleys.

The expansion of the Azores Anticyclone will guarantee atmospheric stability over much of Italy from Monday 21st to Wednesday 23rd, with clear skies and temperatures above average in the North and Centre, while the South and Sicily will remain affected by residual instability and scattered rain, awaiting a cooler change in circulation from Wednesday.

According to iLMeteo.it, the beginning of autumn in Italy will be characterized by stable and sunny weather thanks to the Azores anticyclone, with temperatures above average. However, an increase in rainfall is expected in the coming months, especially in the Mediterranean, due to high sea surface temperatures which favor the formation of storm cells and potential supercells.
