– If you live in Oslo, there is a 60 percent chance that it will snow on Christmas Eve. Previously, there was an 80 percent chance of snow on Christmas Eve. We also see similar changes for other cities and towns in the east and south, says climate researcher Helga Therese Tilley Tajet of the Norwegian Meteorological Institute.
In Bergen, on the other hand, there is only a 23 percent chance that it will be a White Christmas. Solund in western Norway has the lowest probability at just 13 percent.
In several places, however, there is still a 100 percent chance of a White Christmas, including in Trysil, Engerdal and Røros, according to an overview from the Meteorological Institute.
In eastern Norway, December has been 1.2 degrees warmer in the last 30 years, compared to the previous period. We have to go back to 2012 to find December with a monthly temperature below normal.
– The increase in temperature has caused a more frequent temperate climate and more rainfall, such as rain at Christmas. Thus, the average snowline has slid inland and upward in height, Tajet says.
In the lowlands, now only in Troms and Finnmark the chance of a White Christmas remains high. There is a chance that it will snow on Christmas Eve by up to 90 percent, writes the Meteorological Institute.
