Despite the return of winter air, today in Lithuania there is a medium or strong gust of wind to the south and southwest, and in the western part, a west wind, which carries portions of air of marine origin towards the interior of the continent.
From today until Tuesday, the average air temperature will rise above 0 C throughout Lithuania, and atmospheric fronts traveling from the Northeast Atlantic will cause rainy weather (in places with sleet).
It is forecast to drop to 10-15mm this weekend and to 20mm in the western part of Lithuania, mainly rain and sleet. This is around 40-60 percent. monthly rates.
Such a sudden change in weather conditions – strong winds, warming and liquid phase precipitation are likely to lead to the complete melting of the Curonian lagoon (there are still larger areas of continuous ice in the southern and southeastern part of the lagoon), melting the Remaining snow (mainly in the eastern and southern part of Lithuania) will clear the rivers of ice and greatly weaken the ice cover of ponds (especially the Kaunas lagoon) and lakes. The precipitation will partially prolong the weakening of the tsunami where it has not yet ended.
In the smaller rivers of western, central and northern Latvia, the situation is similar to that of Lithuania: the flood wave is already weakening (Gauja, Lielupė, Venta, Salaca, etc.), but in the middle of Daugava , Aiviekste and In some other rivers in eastern Latvia, the spring flood continues.
The next days
Today, the deep cyclone valley (north central Faroe Islands – 960 hPa) with rainfall flows through Lithuania. Tomorrow it will be the least active, but with rainfall, atmospheric front.
On Sunday, the center of the cyclone will approach Lithuania from the west and on Monday, another atmospheric front. The reason for such a rapid change in bar structures with precipitation is the Atlantic cyclone series.
This time, the peculiarities of its movement are classic: the cyclone at the forefront of the series occupies the northernmost position in Europe, the next, younger, travels a more southern trajectory, and another one glides through Central Europe. Finally, at the end of the cyclone series (averaging 3 to 5 cyclones), the high pressure ridge intensifies and cyclonic activity in Europe is temporarily interrupted.
Therefore, this ridge will stop the western air mass transfer from Tuesday, but will strengthen the north. As a result, the climate will cool almost all of Europe, except for the north-west and south of Russia. By the middle of next week, a cold continental air mass will dominate much of Europe.
The night will be cold again and during the day there will be light snow or sleet, with light to moderate north winds. During the day, the air temperature will rise above 0 C, but the sensory temperature will remain low. We could expect more significant climate changes (i.e. the next strongest warming) next weekend, when the marine-derived air mass again reaches the north-western Baltic region.
Phenomena in late March and early April
This period with frequent changes in air masses and temperature fluctuations is not anomalous either for Lithuania or for Central Europe. Although it is now a calendar spring, according to the characteristics of large-scale atmospheric circulation, March is classified as the winter season.
And it is only at the end of this month that centers of atmospheric activity, such as the Siberian (Asian) high-pressure system, the Icelandic and Aleutian low-pressure systems, and the subtropical anticyclones of the Azores and Hawaii (Pacific) , they tend to change. from their typical locations.
On average, starting next week, the radiation balance in Lithuania will change from negative to negative, which means that the solar energy reaching the earth’s surface will start to exceed the radiated energy: the surface will acquire a trend of heating.
During the remainder of March and early April, stronger weather anomalies are not expected in both Lithuania and the Baltic region. Anticyclonic weather is forecast more frequently in the second half of the month, so the probability of precipitation will be lower and the duration of insolation will increase.
