Scandinavia is due to experience a cold spell this week, due to the current position of the polar jet stream to the south, combined with an area of high pressure becoming more dominant. This will allow colder polar air to flow southwards into the region, with temperatures plummeting to up to 20C below the seasonal norm from Tuesday onwards.
Wednesday and Thursday are likely to be the coldest days, with temperatures forecast to fall below -20C in parts of central Sweden and Norway overnight. The low temperatures are expected to persist through the weekend and possibly into next week. However, there will be a shift to more unsettled weather from Friday, with lower pressure moving in from the west, thus creating the potential for significant snowfall over the weekend.
