G. Stankūnavičius predicted that the spring weather in almost all of Europe was stopped by the high pressure system established over the Northeast Atlantic region and Iceland.
“These pressure field structures are called blocking anticyclones, ridges or simply blocking processes. The name itself testifies that the pressure field of such a structure completely closes the path for cyclones from the Atlantic to the east.
As in late autumn, winter and early spring, Atlantic cyclones are the main source of heat and humidity in northern and eastern Europe (less frequently in the center). When the predominant western airflow closes, it is replaced by others: north, east and sometimes south, “he explained.
According to the climatologist, in the coming days, the air flows towards Lithuania, as well as towards the entire Baltic region, will rotate from the north and northwest, and the Atlantic cyclones with their wind and atmospheric front systems will not be able to reach the Lithuanian territory for some time.
“However, an active cyclone, which has started over the cold polar waters (Greenland Sea), is expected to approach the eastern Baltic coast tomorrow. The first signs of the approaching cyclone are the intensified southwest wind in the Lithuanian coast, which will turn west from Saturday night and can reach the stormy wind criterion (17-20 m / s).
Later on Sunday morning, the wind will turn to the northwest and gradually weaken. In most of Lithuania, Saturday afternoon and Sunday will be windy, and the wind speed in gusts will reach 12-17 m / s. This cyclone will bring a little warmer air to Lithuania for a short time, even if it comes from the polar latitudes. “
G. Stankūnavičius predicted that on Saturday the air temperature would rise above 0 ° C almost everywhere, and on the seashore, due to the sea wind, to +2 – +4 ° C. As the cyclone retreats to the east and southeast, cold and dry Arctic air will re-enter Lithuania from behind.
“On Monday, with the strengthening of the anticyclone over Scandinavia, the pressure will increase, the wind will weaken and the night cold will increase. On Tuesday and Wednesday nights, the thermometer bar will drop from -8 to -12 ° C and will not rise to 0 ° C during the day.
Cold weather will continue in northern and central Europe over the weekend and across much of Europe through the first half of next week. The cold of the night will also reach the Mediterranean coast. The warmest in continental Europe will be in Portugal, and more specifically in its western and southern regions, where daytime temperatures will rise from +16 to +21 ° C “.
He also noted that today the weather will also be changeable: the windy wind and the sun will be replaced by globular cumulus clouds that travel from the northern part of the Baltic Sea. As these types of clouds pass, heavy rain is expected in the short term, mainly drizzle and snow, and a sudden increase in wind.
“The night will be cold again and tomorrow, as has already been said, the wind will be stronger for longer. Spring storms are a rare phenomenon on the Lithuanian coast, but tomorrow’s storm will certainly not be the last. In the second half of next week, probably on Thursday, a very deep and active Atlantic cyclone will approach Scandinavia, so on those days (next Thursday-Friday) a storm is expected again on the Lithuanian coast, which will be more stronger than tomorrow’s storm. .
In addition, this cyclone, with its strong wind system, will displace the cold and dry air, opening the arrival of air masses of marine origin to Eastern Europe. Precipitation is also expected to increase, mainly rain and air temperature from +4 to +8 ° C. “
The climatologist explained that, according to the long-term weather forecasts of the European Center for Medium-Range Forecasts (ECMWF), in the second half of this month a stronger western transport will prevail in northern Europe, causing a warmer climate than usual in more parts of the continent and higher rainfall in northern Europe.
