The week will pass with changeable weather, while a new wave of bad weather is expected on New Year’s Eve.
The above is predicted by the Open TV meteorologist, Klearchos Marousakis in a post on Facebook, noting that today on New Year’s Eve we expect a slight invasion of cold in our country so the temperature will drop with emphasis on the central and northern continents with the snow to do it again. its appearance in our mountains probably in the northwest and lower. During the New Year the weather will improve with the cold but quite intense of Thessaly and above with frosty conditions at night and in the morning.
Weather forecast
The new week with a changing weather
The barometric low that affected our country in the last 24 hours (first map attached) is slowly moving towards the east of the Aegean, resulting in the withdrawal of rains and storms. However, because the bad weather system was quite deep and organized, it has left unstable gas masses and therefore unstable weather will remain in the western parts.
Southerners insist
As we can see from the second attached map, bad weather systems continue to come to us from central Europe and the central areas of the Mediterranean, with the result that, as we observe with the black arrows, the flow of gas masses is from the southwest to northeast. This means that Southerners will insist on keeping the humidity high and not allowing the mercury to sink.
New wave of bad weather New Years Eve and day
Unstable weather as mentioned above will extend throughout the new week where this instability will peak in two phases. The first phase of the peak is expected on New Year’s Eve with rain and thunderstorms in several areas. In fact, on New Year’s Day we expect a slight invasion of cold in our country so the temperature will drop with emphasis on the central and northern continents with snow to reappear in our mountains, probably in the northwest and lower. During the New Year the weather will improve with the cold but rather intense Thessaly and higher up with frosty conditions at night and in the morning.
The second phase of the peak of unstable weather is expected on Sunday with heavy rain and thunderstorms, very strong southerly winds and high snow in the mountains as temperatures will rise with the removal of cold gas masses further north. The above is reflected in the precipitation maps in the third attached map where day by day we arrive until Sunday. The darker the colors, the stronger the rains.
More winter weather from Epiphany onward
With the winter siege of 2/3 of the Old Continent essentially shutting out the extreme southeast of Europe, the first days of January seem to be advancing. So this accumulated cold seems to reach our country. In the attached fourth map we present a possible barometric arrangement scenario whereby an atmospheric mountain is expected to develop in western parts of Europe, paving the way for very cold weather in our region.
In the last attached map you can see the flow of cold air (blue color) towards the end of the video, that is, after January 6 to 7.
Atmospheric circulation is complex: distant forecasts are fragile
This year, after several years, two huge atmospheric mountains were activated in the atmosphere of Europe, one in the western parts of the southwest and the other in the eastern parts of the northeast. In meteorology these atmospheric mountains are called anticyclones or fields of high barometric pressure.
Where does the prognostic difficulty lie and why is Winter late and “torturously”?
Anticyclones are “heavy” atmospheric systems that evolve slowly over time. As a result, when they grow in some geographic areas, they “freeze” the evolution of the climate, following a recurring climatic pattern for many days. This can reach and in some cases exceed a month in duration so that these climatic systems change their structure or change their position under the pressure of the rest of the atmospheric circulation. This is why for many days we remain in the stable weather pattern of the south with the snow staying high or even slightly lower in the northwest. Therefore, we will have to wait for the time differences in terms of the evolution of a slightly more distant forecast. These time deviations usually range between 5 and 10 days and we usually say because chaotic phenomena do not enter into limits, on the contrary the limits in these cases are to break.
