The so-far mild winter took a colder turn over the Christmas and New Year holiday, and now there looks set to be a real blanket of snow by Monday morning—just in time for many commuters’ first drive to work after the break.
The snow is the result of cold air moving in from the south-east, across the Gulf of Finland. As it crosses the unfrozen sea it is likely to cause a lot of precipitation when it makes landfall, and along the south coast that will probably take the form of heavy snow showers.
Sunday night is forecast to see the heaviest showers, with temperatures around -10 degrees. If this dry, cold snow falls onto icy roads, it will make road surfaces especially difficult. Visibility will drop too in the heavy snow showers.
In previous years similar conditions have brought several shunts and fender-benders in the capital city region.
