Scandinavia has seen a spectacular turn of events in that milder air has advected eastward and temperatures in some places are over 30°C higher than they were just 48 hours earlier. The ease with which this transition occurred has been truly remarkable in nature, with little or no precipitation on the change from severe cold to milder weather.
Here’s a thermograph from an aerodrome at Jokkmokk in northern Sweden to see the remarkable rise in temperature from a low of -38°C on the 5th, to a high of 5°C earlier today.
