Greece is experiencing continued winter weather, with increased cloud cover and rain forecasted across the country through the end of the week. Meteorologist Anastasia Tyraski warns of thunderstorms primarily in the central and southern Aegean, along with snowfall in mountainous areas and strong northeasterly winds reaching up to 9 Beaufort. A new weather system is expected to bring even colder air masses from the north, leading to possible snowfall at lower altitudes. Gradual improvement in weather conditions is anticipated by early next week.
