Italy is experiencing stable weather driven by a high-pressure system, bringing widespread sunshine, mild temperatures, and limited rain, with southern regions such as Sicily, Calabria, and Puglia seeing temperatures above 20°C.The high-pressure is expected to strengthen further, influencing mountain regions and cities, keeping the zero-degree line at around 3,000 meters, and maintaining pleasant and dry conditions through the national public holiday and main festivities, including the pope's veneration of the Madonna statue in Rome and the lighting of the Christmas tree in Piazza del Popolo.Rome has reopened its tram network and launched its Christmas shopping season, while forecasts indicate the mild weather will persist through Christmas, with only isolated rain in southern areas and some snow in the Alps above 2,000 meters during the upcoming weekend.
