A level 2 was issued across parts of Germany and the Northeast Netherlands mainly for extreme rainfall, and to a lesser extent for large hail.
A level 1 was issued across large portions of Central Europe and the West Balkans for extreme rainfall and large hail.
Quelle: ESTOFEX http://www.estofex.org/Fair low-level humidity and mediocre lapse rates are projected to lead to moderate instability in response to strong diurnal heating. A few isolated large (2-4 cm) hail and heavy rainfall events are likely to occur, even though the storms will probably be rather poorly organized due to limited vertical wind shear. A somewhat enhanced risk may exists along the southern Alps, where upslope flow will increase the risk for training storms somewhat.
