According to the meteorologist, a mixed precipitation is possible today: snow, rain, lijundra. There may still be a little snow at the weekend and next week the snowflakes will be replaced by rain.
“At the beginning of the winter calendar, people complained that they were already tired of the dirt and bad weather, bad that there was no snow and so on. Not only did the cold hit this week, but coupled with the strong winds, it resulted in a low sensory temperature, also known as the wind break temperature or break index.
For example, when the air temperature is -3 ° C and the average wind speed is 12 m / s, the sensory temperature is -12 ° C. Therefore, those who most complained about the autumn dargana they quickly changed their minds. The lowest temperature was -7.5 ° C in Vilnius, -8.6 ° C in Švenčionys and Dūkšte, -5.1 ° C in Kaunas and highest in western Lithuania. Compared to the cold records from early December, it is cold here. And here, the southeast wind had strengthened in some places at 14-19 m / s, in addition, it lasted several days, ”says G. Stankūnavičius.
The scientist explains that such a cold and windy climate was caused by a very stable and strong anticyclone.
“The anticyclone system made the air cool and the large pressure gradients at the edge of the anticyclone caused the wind. The center of the anticyclone itself is expected to move slightly to the east, but its westward-extending ridges will affect the weather in eastern and partly central Europe until almost the end of next week.
Last night, a patch of warmer air came to Lithuania from the south. As the cold air in the anticyclone is not very mobile, the heat first reached above the boundary layer, about 700-1000 m above the ground. At this altitude, the temperature rose above 0 ° C and the air was saturated with humidity.
Therefore, in eastern and central Lithuania, lijundra first appeared, then ice grits, and finally snow. But the result of all this process is only 1-2 cm of snow. It did not form at all in western Lithuania, ”explains G. Stankūnavičius.
The meteorologist claims that today the weather in Lithuania will continue to warm, the temperature will rise above 0 ° C.
“Mixed light precipitation is expected (snow, rain, possible lijundra), the wind direction will remain the same, southeast, but the wind is weaker than earlier this week.
On Saturday night the warmer weather will go away and the day will be cool again: from -3 – -4 ° C in the east to +1 – +2 ° C in the west. Light rains are expected, mainly snow. Sunday will remain cool and another area of rainfall will approach Lithuania ”, he shares the forecasts for the weekend.
According to the review, the average temperature will be positive throughout Lithuania from Monday.
“The wind will be weak or medium, but the wind from the south rhombuses (PR, P then PV) will continue to prevail. No significant precipitation is forecast, although a higher probability of precipitation (mainly rain) is expected in the middle of next week.
The polar anticyclone over the central Arctic will intensify next week, eventually having to replace the large-scale hot and cold fluxes that have prevailed so far. As a result, the second half of the month will cool down in Northern Northern Europe. Anticyclonal weather in the Baltic region is forecast with the turn of the new and old year, but the reliability of these forecasts is not high, ”says G. Stankūnavičius.
