In the next few days, such a transfer will be predominant. It is true that it can be of two types: north and south directions. The first is related to the entry of cold air and the second is mainly related to warm air (south winds do not always carry warm air). This weekend, the weather will travel to Lithuania and the entire Baltic region from the polar latitudes, more precisely from the Norwegian Sea and the North-East Atlantic.
It is not very cold, and traveling through open sea areas and crossing the Scandinavian mountains will be even more transformed. As a result, the weekend will remain relatively cool, in places with rain, and at night, when it clears, the air temperature will drop to 0 C or below. As mentioned above, this is very typical weather for early April.
Tomorrow Saturday, the low-pressure area northeast of Iceland will greatly strengthen, turning into a deep cyclone on Sunday with a center in the southwest of the Barents Sea, and the cyclone circulation system will cover all of Scandinavia, the Baltic region and northwestern Europe. .
Around the same time, a high pressure ridge will strengthen over the northeast Atlantic, which will then cover the entire Greenland-Iceland region. Such an interaction between two very intense but opposite pressure signs will lead to a strong transfer of sea air from the Arctic to Western and Central Europe.
First on Sunday, strong winds and sleet will hit the Faroe Islands, Scotland and Northern Ireland, then winds from the north and northwest will sharply intensify in the North Sea, the English Channel, the Belgian coasts of Belgium and France ( until 22-27 mrs).
Tuesday night will cool down in northern Germany, the Benelux countries and much of France. On Wednesday, a cold snap will hit southern France, the Pyrenees, much of northern Spain, Catalonia (Spain) and even the Balearic (Spanish) and Sardinian (Italian) islands.
The lowest minimum temperatures will be in the mountainous areas: Scotland at -14 C, Ardennes at -7 C, Central Massif, French Alps at -10 to -12 C, Central Cordillera (Spain) at -4 to -6 C. Abnormally cold will be in almost all central and southern Europe.
What will happen during Easter and beyond?
With the aforementioned cyclone over the Barents Sea and northern Scandinavia strengthening on Sunday, the north winds in Lithuania will be replaced by a moderate wind from the southwest. Therefore, a sudden and intense cooling is not expected during the holidays in Lithuania. On the contrary, the air temperature during the day will rise to 7-12 C.
On Tuesday, an active atmospheric front will pass through Lithuania from the west, bringing rain and sleet, and on Wednesday it will reach low-pressure areas from the south, likely to cause sleet in eastern Lithuania as well. In the second half of the week, Lithuania, like much of Central Europe, will be in the upper cold valley catchment area, so cool weather with rainfall is expected.
Long-term weather forecast data suggest that from the middle of the month, higher pressure fields will be more frequent in Eastern Europe, so warmer and drier weather is expected in the second half of the month.
At present, large-scale pressure fields in the Northern Hemisphere are changing due to rapidly changing radical equilibrium conditions. This is happening not only in the North Atlantic, but also in Eurasia and the North American-Pacific sector.
The Siberian (Asian) anticyclone debris is expected to disappear completely in the coming weeks, the low pressure zone in Iceland will weaken and the low pressure zone in Aleut will become dormant in autumn. Such transformation of the main centers of atmospheric activity also affects meteorological forecasts, during this period their validation is poorer, especially at mid-latitudes.
If a warm spring has not yet arrived in our country, it does not mean that it will not arrive elsewhere. During the next week, due to the predominant remnant of the south, the Urals and western Siberia will be very warm, even the arctic coasts rising to 0 ° C will be higher than the norm. Abnormal cold weather will occur in most of eastern Siberia and Alaska.
