Current situation and outlook

The Alps are currently located between the area of influence of a powerful high (relatively far eastern variant of the Azores High) over Western Europe and a low centered roughly over Ukraine, which is reaching out towards us from the other side. The high and low are hanging somewhat askew, creating a north-easterly flow. The result of this constellation is currently still rather cool weather with partly cloudy conditions and showers in the north. South of the main Alpine ridge, the weather is generally friendlier, but there are still holes in the cloud cover in the north today (Wednesday).

In the course of Thursday, a warm front with precipitation and a rise in temperature will reach us before a new wave of cold air reaches the Alps: a new low-pressure complex will establish itself in the western Atlantic, the Azores High will tilt slightly to the west again and a Scandinavian low will brush the Alpine region. In terms of precipitation, northern accumulations in the eastern Alps are favored. The snow line will be higher than recently. In the Eastern Alps, it will probably still snow in many valleys, but the precipitation may change to rain over time. It is still unclear exactly how heavy this will be, but a report from the oracle would be possible, especially for the eastern northern Alps.

Since the PowderGuide.com weather service has now also arrived on PG 3.0, you can take a look at the potential fresh snow here.

Christmas weather

The low pressure system will leave relatively quickly and the precipitation is likely to subside everywhere over the course of Saturday. For the 24th, it currently looks quite mild (more so in the west than in the east) and sunny. Despite a noticeable moderation, there is no reason to fear a repeat of the summery Christmas thaw of the last two years in this extreme form. In the lowlands, however, it is doubtful whether the snow can hold if it is not preserved under the inversion.

The Christmas holidays are also expected to remain rather mild and relatively sunny, with the flow increasingly turning to the southwest at the beginning of next week. This will make it cloudy in the south and foehn-like in the north.

The crystal ball...

...not only glitters on the Christmas tree, the speculative crystal balls of the weather models will also sparkle with color from the middle of next week. Perhaps Santa Claus, Santa Claus, Mother Hulda and/or Ullr will make sure it stays that way.

The DWD has responded to the judgment already mentioned here in the lawsuit filed by WetterOnline against the DWD's previously free warning weather app. The full version of the app now costs a one-off fee of €1.99. Those who enjoy internet anger can find it on Twitter or in the comments of the Facebook posts of the two opponents.

The NOAA reports that 2017 is still on course to be the third warmest year globally in the 138-year history of measurements. The extent of sea ice in the Arctic in November was 11.6% below the average for the period 1981-2010. The ice extent in December was similarly below average. In the Antarctic, the average sea ice extent in November was 5.6% below average.
