A detailed picture of weather developments through Christmas and New Year has been presented by meteorologist Klearhos Marousakis in a new social media post. He warns of atmospheric instability and successive waves of bad weather, with an initially autumnal pattern becoming more wintry as the turn of the year approaches.
In particular, he states in his post:
“With the retreat of the atmospheric ‘ridge’ starting tomorrow, the conditions will allow bad weather to affect our country as well. This will bring a return to autumnal conditions after a brief period of milder weather, at least in terms of rain and snow.
From tomorrow onward, a ‘parade’ of successive low-pressure systems will begin, leading us into Christmas with highly unsettled weather conditions, as we noted in our initial assessments several days ago.
TWO WEATHER PHASES UNTIL CHRISTMAS
Regarding the weather trend up to the turn of the year, we can distinguish two phases.
PHASE 1 (AUTUMNAL WEATHER)
The main characteristics will be frequent and sometimes heavy rain and storms, strengthened southerly winds over the seas, and snowfall in the high mountains.
This phase, which includes the Christmas holiday, is expected to last until around December 28.PHASE 2 (WINTER WEATHER)
The main features will be a significant drop in temperature from north to south, the prevalence of stronger northerly winds, heavy rainfall near coastal areas, and substantial snowfall in the mountains, possibly extending to lower elevations.
This phase, which will include the New Year, is expected to last through the first days of January.It appears that the collapse of the anticyclone (the atmospheric ridge) is arriving just in time this year, pushing away unseasonably mild conditions and bringing a more typical Christmas pattern — in other words, normal seasonal weather.
