L’last week of the year sees a weather scene characterized by other rains that this time will reach the extreme south and Sicily in a more decisive way. This situation of instability, with a rather mild climate especially in the Center-South, will persist until mid-week. Then to New Year’s, an important weather turning point is looming. An anticyclonic area, with roots in northwestern Africa – explain the meteorologists of IconaMeteo.it -, will determine exceptionally high temperatures, especially in the Alpine sector where the difference could also be of 10-15 degrees compared to the seasonal average. This widespread atmospheric stability will contribute to the return of mists in the Center-North, locally also dense and persistent.
Forecast for the next few hours
Very cloudy or overcast sky with the last bright spells at the beginning of the day in the extreme Northeast and temporary local openings between Lazio, Molise, eastern Basilicata and Puglia. In the morning some rain on the regions of the lower Tyrrhenian Sea and on the west of Sicily; at the end of the morning weak snow in the western Alps above about 1200 m and some rain on western Liguria and western Sardinia. In the afternoon, even moderate rains in Sardinia and widespread in Liguria, weaker and more isolated in lower Lombardy, Emilia, Tuscany, upper Lazio, Umbria, the interior of Campania, Tyrrhenian Calabria and western Sicily; weak snow up to 1000-1100 m in the Piedmont and Valle d’Aosta Alps. In the evening scattered rains, locally moderate, on the Tyrrhenian regions and Sicily with possible showers or thunderstorms in the west of the island; local rains on eastern Liguria, southeast Lombardy, lower Veneto, Emilia Romagna and the rest of the Center.
