Current situation and outlook

The low pressure system bobbing around over the Alps has been cut off from the main current by a high-pressure bridge in recent days, meaning that no further cold air could be brought in. Instead, a slight south-easterly flow developed (low pressure turning anticlockwise, high pressure clockwise). As a result, there was again heavy precipitation in the south, as predicted by the oracle. The south-easterly flow already weakened yesterday - the high pressure bridge is being dismantled and our low pressure trough will regain some connection to the colder air masses in the north today. These are flowing towards us today, joining up with mini low Ahmet in the north-east and together they are building up in the northern Alps. Compared to the previous days, it is a little colder and much cloudier. Widespread snowfall down to low altitudes, but not much.

The mini-northern congestion will soon be over. Tomorrow, the sun will shine away from the congested areas in the morning and the clouds should also have cleared on the northern edge of the Alps by midday. It will remain cold and the few centimetres of fresh snow from today will at least decorate the northern Alps nicely. Friday should also be a calm, sunny, cold winter's day. Things will get a little more lively at the weekend. It will become cloudier - more so in the west than in the east - and precipitation will set in again on the southern slopes of the Alps. However, it doesn't look like there will be another südstau in the league last week and the forecast is generally still rather uncertain. The Atlantic blockade is gradually being broken up and there is at least a chance of a change in the overall situation and more Atlantic influence from the northwest in the coming week. At the moment, I wouldn't expect much in terms of snow for the northern Alps, but at least the situation in the crystal ball doesn't look quite so entrenched anymore.

2020 in climate statistics

At the start of the new year, it's important to take a look back at the old year. In a nutshell: It was very, very warm. The WMO's global evaluation is not yet finalized - after all, the new year is only a week old - but it looks like 2020 is in second place in the global temperature ranking, ahead of 2019 and after 2016 . In Germany, 2020 was also the second warmest year in recorded history, just behind the record holder 2018. The last decade was very warm overall, with the four warmest years in Germany since 1881 being 2018, 2020, 2014 and 2019, according to the DWD analysis. The situation is similar in Austria, where 2020 was probably the fifth warmest year in recorded history. If you only look at the mountain regions of Austria, 2020 even set a new time series record. In Switzerland, 2020 is roughly on a par with the previous record year of 2018.

It will be interesting to see what the new year brings! It would be quite a surprise if 2021 sets new cold records, but there is bound to be varied weather - sooner or later...
