Weather: Cold snap to bring a 10°C plunge in temperatures – Where snowfall is expected

The weather pattern is set to change sharply from tomorrow, Sunday (10 January), with a steep drop in temperatures accompanied by strong winds and thunderstorms.

“The change in weather beginning tomorrow, Sunday, signals a drop in temperatures, which will initially be felt in the northern regions and will gradually spread to the rest of the country,” meteorologist Theodoros Kolydas wrote in a post on X.

“In many areas of central and northern mainland Greece, maximum temperatures will fall into single-digit values, giving the weather a distinctly wintry character. Overall, the temperature drop is estimated to be around 10 degrees Celsius,” he added.

A significant fall in temperatures from tomorrow is also forecast by the National Observatory of Athens / meteo.gr.

“The drop will first be felt in the north and then across the rest of the country, and in many areas it will exceed 10°C. On both Monday 12 January and Tuesday 13 January, temperatures will remain low, and frost is expected in the morning hours of both days (temperatures below 0°C even in lowland areas of central and northern mainland Greece),” meteo notes in a related report.
