Temperatures are poised to plunge next month in Northern Europe as cold air blows in from the Arctic in what will be the first proper winter test for the region’s fragile energy systems.

The Nordic region and Germany will see temperatures well below average for this time of year, with levels in Helsinki falling as much as 6.9 degrees Celsius (12.4 Fahrenheit) below average on Tuesday and Wednesday, Maxar Technologies Inc. said in a report. It’s only southern Europe that will be spared the frigid temperatures, forecasters warn.
