Towing services in Stockholm were pushed to capacity as motorists slid off the slushy roads around the capital.
But despite encountering large numbers of road accidents, police forces around the country had mercifully few reports of serious crashes.
While most of the accidents were largely unavoidable, police said a three-car pileup in Brahehus in southern Sweden was caused by an Italian driver with summer tyres.
“Not very clever considering the prevailing road conditions,” said a police spokesperson.
Chrysanthi Grammatopoulou at meteorological agency SMHI said snowfalls were expected along the entire east coast all day Thursday.
“But there will be occasional breaks,” she said.
The snow is also expected to drift inland to mountainous parts of western Norrland.
“There has however been an improvement in Västra Götaland, and it is also clear in parts of Värmland and northwestern Götaland. In Skåne too things have almost cleared up aside from a few light snow showers,” said Grammatopoulou.
