Hello,
unfortunately only briefly and without a card (because I am a bit stressed out ..) a new assessment of the air mass limit on Austria. It could, and so it is worth at least this small update before are parts of our valued Alpine republic a rather wintry interlude. It's already cold, especially in the east, but the snow is lacking, thus far ... to the east gets in the foreseeable future from not different in the case but in Northern Tyrol, Salzburg and Upper Austria, partly in Vorarlberg!
It should here namely the stationary front that no further progress is to the east, especially in the border triangle Salzburg / Tirol / Bavaria, but come down a good amount.
Several criteria for vigorous and constant output Snow should be met locally:
frontal zone
Warmluftransport in height at ground level
Kaltluftadvaketion
At the height of the mountain ridges north-west flow, so storage effects at ground level easterly current.
A 30 + Friday evening there might already be in it .... More critical the situation in Vorarlberg, here the mild air is already quite close, so Baatz is in the air ... east of Linz scents after a short-18Z GFS confusion of arriving but nothing more, provides the front does not continue to the east, before being pushed back on Friday after Weschten.
It could be that the snowfall for a Northwest Höhenanströmung also considerably far lunged over the main ridge to the south, so Carinthia, East Tyrol and the upper Mur valley, because of ground-level Ostströmung and very stable conditions ... But this is still a shaky bissl, we see tomorrow.
This in a nutshell ...
