Even if the peak of the Arctic cold phase is reached at the weekend, the deep Atlantic depression will continue to influence the weather in Italy for several more days with new opportunities for rain and, most importantly, snowfall. Therefore, low pressure and accumulation are visible not only in the Alpine and Apennine areas.
Lots of snow coming
There are many webcam images that they show Aosta550 meters above sea level, with the first real snowfall of the season: but the peak is yet to come with white flakes falling from hilly heights in mountainous areas, namely from a height of 700 meters, to climb above 1,300-1,400 meters in the Apennines. If snowfall starts to fall on Sunday evening, then especially on Monday 24 November it will fall heavily due to the arrival of a front from France which is again driven by cold northerly currents.
Over 50cm, that’s where it is
“Significant accumulations are expected, especially on the borders of the Alps (Val d’Aosta, western Piedmont, Upper Lombardy, Alto Adige). Popular locations such as Courmayeur and Livigno can see fresh snow reach and exceeds half a meter thick on Tuesday morning”, experts explain Ilmeteo.it. In short, a good snowpack for the pleasure of tour operators and a ski season that starts under the best of cover.
What is gelicide
In flat areas, even if it does not snow, dangerous phenomena can occur, especially in road traffic: what we are talking about is “freezing” also called “freezing rain”, which is when rain or drizzle remains in liquid form even though the outside temperature is below 0 °C. In this way it immediately freezes after coming into contact with the ground, making it slippery due to the thin layer of ice. This phenomenon occurs because ““cold air in low layers (close to the ground) will not be enough to hold snow on the plains, due to softer layers of air at high altitudes (thermal inversion), which will make the flakes melt before they hit the ground.” the experts added.
The next trend
Bad weather will keep the North-Central region under control at least until Tuesday 25 November: from Wednesday clouds and rain will move to the far South and Sicily with an initial improvement in the region
central-north. However, the weather will remain cold due to northerly winds that will contribute to keeping temperatures below average for the period and, at night, even below zero in the northern plains.
