Low pressure system Olivia brings the post-Valentine's Day powder announced by our colleague Oracle and finally puts an end to the eastern frost. After an impressive cold spell, the Atlantic slowly regains its importance.

A while ago, the possibility of a changeover from westerly weather to easterly cold was discussed here. As we all know, this didn't happen after all and the Atlantic has thrown one meter after another onto the north-west's measuring gauges. Now the cold from the east is making another attempt.

Last week finally brought the long-awaited onset of winter in the north. While the base in the south grew with every Italian low, the northern Alps have lagged far behind. All the more pleasing now is the abundant northern accumulation: on Saturday (11.12.), a warm front nestling lovingly against the Alps brought up to half a meter of fresh snow in the (eastern) northern Alps, in addition to the starter that fell the day before.
