An extensive low pressure from the Norwegian Sea moves in with snowfall over Norrland and Svealand during Friday evening. The snowfall can be heavy in places. During Saturday, the low pressure then spreads with both snow, rain and wind also to the south.
— Then the low pressure moves away towards the Baltics and colder air moves in from the north. Mainly northern Sweden gets the cold. It will also get colder in the south, but not to the same degree, says the meteorologist Lars Knutsson at SMHI.
How cold it gets depends on whether it clears up.
Svealand can expect 10-20 minus degrees
— In southern Sweden, the clouds will probably dominate. But if it clears up, it could be 10–20 minus degrees in Svealand from Thursday to Friday, says Knutsson.
During the extreme cold at the beginning of January, just over minus 43 was measured in Lapland.
— As cold as last time, let’s hope it won’t be. But should it be clear and windy in Norrland, it will be down to minus 30.
The cold air in the north looks set to remain at least until next weekend.
Avalanche warning in the north
Snowfall and strong winds in connection with the weekend’s low pressure means that avalanche warnings have been issued for the southern Jämtlandsfjällen and the western Härjedalsfjällen. The warnings are a three on a five-point scale, meaning the risk of avalanches is significant.
