Over the weekend, the air temperature both at night and during the day will be in the range of -3 to + 3 degrees Celsius, somewhat warmer on the sea coast in Kurzeme at up to +5 degrees.
There will be little rainfall, so the layer of snow that formed on Friday will not increase significantly, but it will likely not melt much, either.
The prevailing winds will be slow to moderate north and northeasterly winds, so will feel chilly.
At the beginning of next week, the western and central parts of Latvia will get a little warmer, but in most of Vidzeme and Latgale the temperature will still often be a few degrees below zero. It will rain in the west, it will snow in the east, and the layer of snow will become thicker.
In the east of Latvia, the average daily air temperature will drop below zero, and it is very likely that this will be the case for several days in a row, which could therefore be considered the beginning of meteorological winter, though this does not mean that frost will dominate in December.
Last year, meteorological winter in the east of Latvia started at the end of November, but in the following winter months the average daily temperature dropped below zero only on some days, and very little snow was seen throughout the entire winter season.
Long-term forecasts from the US National Oceanic and Atmospheric Administration show that the average temperature in Latvia in December will be around two degrees above the climatic norm, which means that the last month of the year will be colder than November, but will still be considerably warmer than what we associate with a bitter Baltic winter.
