The US-based weather agency The Weather Company has revised its forecast for the December-February period to say that colder weather than expected should be in store for Norway.
"The colder pattern that started in October has persisted into November, this is a fairly clear sign that our original ideas for this winter were a bit off base," said the Weather Company's chief meteorologist, Todd Crawford, forecasting below-normal temperatures across the whole of Scandinavia.
"It is clear that the polar vortex is weaker than we originally expected and that more blocking is likely going forward, especially in the Eurasian sector. Given this, along with the continued colder-looking model guidance for December, we have made significant colder changes to our forecast."
The agency predicts that December will see temperatures fall to below-normal for the Nordic region, followed by slightly warmer temperatures in January before again falling in February.
Already in early November, some residents in the southern part of the country were left without power after heavy snowfall. Other areas, however, have experienced warmer than normal conditions, with Tromsø this week setting an all-time record for the longest wait for winter snow and Svalbard being recently pummelled by a powerful rain storm at a time of year that usually sees snowfall.
Another weather agency, the Danish Meteorology Institute, also said last month that the Nordic nations should expect their coldest winter in years.
