The latest estimates from two weather forecast models for Christmas Day were presented on Monday afternoon by Thodoros Kolydas.

The former director of forecasts at EMY noted that, despite some differences between the two models, the overall outlook is for “mild temperatures, with occasional showers after Saturday and no particularly strong winds.”

Explaining the variations, Kolydas said, “The westerly or easterly position of the surface low in the Central Mediterranean plays a major role in shaping the weather on Christmas Day.”

Marousakis: The time of the ‘omega blocker’

Earlier today, Klearhos Marousakis spoke about weather influenced by the “omega blocker” until Friday, which “keeps bad weather at bay for a few more days.”

However, he cautioned that “this atmospheric ‘mountain’ may act as an umbrella of protection, but it doesn’t mean the weather will be perfect.”

“From Lamia and further north, winter conditions will dominate, with bitter cold during the day, freezing temperatures at night and in the morning, and persistent fog. Further south, although the day will start quite cold, solar radiation around noon is expected to raise temperatures to 16–18°C,” he added.

According to Marousakis, “This pattern will hold until around Friday, when the atmospheric ‘mountain’ retreats and the path for bad weather opens, potentially affecting Christmas. Rain is expected to dominate, while snow will likely remain limited to the higher mountains.”
