A cold mass of Arctic extraction, coming directly from the North Pole, will cross Europe in the next few days and then dive into the Mediterranean Sea, affecting Italy with a real storm of wind, heavy rains and even snow down to the plains. Flakes also in Sardinia, but at high altitude.
Antonio Sanò, founder of the website www.iLMeteo.it warns that until the weekend a cyclone will maintain unstable conditions in the central-southern regions, hitting the Adriatic slopes and the South more widely. Thursday will be the rainiest day for these regions, where in addition to rain, sometimes heavy, it could snow up to 900-1200 meters. Also on Thursday, colder winds will start to blow from the northern and north-eastern quadrants, which will be responsible for a drop in temperatures in the North.
Everything will change over the weekend. During Saturday 7 December, cold air will press against the Alps and, unable to overcome them, will break out into the Mediterranean partly through the Rhone Valley (south-eastern France) and partly from the Porta della Bora (Julian Alps). By the evening, the weather will worsen more and more widely in the North with precipitation of mainly snow on the Alps and Prealps and during the night locally also on the flat areas of Piedmont, Lombardy, upper Veneto and upper Friuli.
On Sunday 8 December the cold air will finally break through the Mediterranean basin and it will be then that Italy will experience a real storm of mistral and libeccio winds, with gusts of up to 90 km/h and consequent storm surges on the exposed coasts, especially between Liguria and Tuscany and on the Tyrrhenian coasts, as well as in Sardinia.
If the weather in the North has already improved, except for the last precipitation in the extreme eastern sectors (snow at low altitudes), the bad weather will concentrate on Tuscany, Lazio, Umbria, Campania, Sardinia and then Sicily. In addition to the heavy rain with the risk of thunderstorms, widespread snow will also fall on the Apennines, favored by the lowering of temperatures at high altitudes. Above about 1000 meters everything will become white, as has not happened for many years in this period.
But it doesn't end here. Next week the climate will cool further, becoming typically wintery. There will continue to be conditions of strong instability in the South and in Sardinia with snow falling even above 6-800 meters. Then, it could be the turn of the North too.
