It seems the cold moved to central Europe, giving us -15 degrees celsius at night in the upcoming week.

It seems that this is directly caused by the arctic temperature rise: https://en.wikipedia.org/wiki/Sudden_stratospheric_warming

Relevant quote: Following a sudden stratospheric warming, the high altitude winds reverse to flow eastward instead of their usual westward. The eastward winds progress down through the atmosphere and weaken the jet stream, often giving easterly winds near the surface and resulting in dramatic reductions in temperature in Europe.

Some of it's here on the west coast of the US too. It hit -18C here in central Oregon the other day, and has been snowing a bunch.

And some of us in Eastern Europe are expecting -24 °C .
