The holiday weekend is set to kick off with a band of snow, sleet and rain moving across the country to the east on Saturday, ensuring a white Christmas for most of the country. Just the far south-west will avoid the white stuff, with precipitation there largely sleet and rain.
"Based on current information the worst of the showers will have cleared away to the east by Saturday evening," said Yle meteorologist Joonas Koskela. "On Christmas Eve there could still be showers in the east and centre of the country."
Koskela says that Saturday 23 December will be cold, with temperatures below freezing across the country. In the south the mercury will hover around zero, in the centre it will be 5-10 degrees below, and in Lapland it will dip as low as 15 degrees below freezing point.
The south-western coast, inland areas of the south-west will be snowless on Christmas Eve, which is the traditional celebration date in Finland. Helsinki could have a sprinkling of snow.
