The general weather situation
Our weather is almost always made over the Atlantic. At the moment, the jet stream there is quite zonal and is pushing a series of fronts towards Europe. Low pressure centers over northeast Canada and Scandinavia "control" the jet. There have already been a few unproductive flakes from this constellation in the last few days. Today (Wednesday) is still fairly calm before the alarm congestion arrives tomorrow.
The Azores High, which is currently located relatively far east off the coast of Portugal, is decisive for this development. It will move a little further east over the next few days and also bulge northwards. This will cause the jet over the eastern Atlantic to undulate - the current will have to move northwards and past the high before it reaches the Alps. According to the current forecast, the high pressure will extend as far as the British Isles on Thursday and Friday. Downstream (to the east) of it, a Scandinavian low pressure system with cold air and fronts will slide southwards. If the high, all other things being equal, were located a little further west, for example over the Azores, where it is usually found, the north-westerly accumulation and the corresponding snowfall would also land a little further west. Details on the core areas of the PowderGuide.com and the snowfall amounts can be found in this very article.
