Könnte ein ganz miserabler Tag für den SO Österreichs werden... Level 3 von Estofex

Convection-resolving models agree on quick upscale growth into a large MCS with a most likely track across much of Slovenia in the evening, including the bordering regions of Croatia and Austria. Supercells will likely bring large to very large hail in initiating stages or generally at the southern flank of such a system. In addition, a tornado is not ruled out, though this risk is mitigated by not too low cloud bases and rather inconspcuous low-level shear. Along the MCS's main body, severe straight-line winds will betimes become the main risk. They may become quite widespread and include some extreme events (>32 m/s).
The mature and finally slowly weakening MCS could persist well into the night or even into the next morning while it continues its track northeastward into E Austria, Hungary and possibly even Slovakia. It will likely bring a prolonged period of heavy rain, and flash floods become another dangerous hazard in the course of the night, especially in S and E Austria where soils are often already saturated. In addition, severe wind gusts or large hail are still possible at the leading edge or under more discrete updrafts, respectively.

tja... wird vor allem für die Feuerwehren im Süden und Osten eine anstrengende Nacht werden, ist zu befürchten.... wie sie im Radio so schön lapidar meinen "Gewitterzelle die von Slowenien Österreich erreicht und im Osten dann bis Wien ziehen könnte"

WRF 4km hat das auch so in der art drin, ebenso Kachelmann. betroffen könnte auch das Salzkammergut sein - dort ist allerdings die "Vorgeschichte" nicht so ungünstig wie im Süden und Osten
