Sudden Stratospheric Warming underway, mid/late January could see some serious winter weather across a large part of Europe

Snip:
Two months ago, we talked about the polar vortex and its influence on the troposphere. Right now, the “Sudden Stratospheric Warming” – a large scale process – is underway and it might have important implications for the rest of the winter.
As it can be seen in the graphic the stratosphere over the Arctic region is undergoing a strong warming event. The mid-stratosphere temperature over the pole is more than 65 °C warmer than in a normally strong polar vortex situation. This helps to weaken the polar vortex and can even cause it to break down into two or more smaller vortices.
