SYNOPSIS

Please refer to the original convective forecast.

DISCUSSION

SE Poland, E Slovakia, W Ukraine...

On the southern flank of a small closed mid/upper-low, thunderstorms are ongoing. Those occurring in vicinity of the low will interact the with 20-25 m/s deep layer shear in this region, and as a result may develop rotating updraughts. As a result, the risk of some isolated large hail becomes large enough to be mentioned here. Furthermore, some strong, possibly severe, wind gusts are possible. The convection will become elevated in the evening, but a (small) risk of large hail may continue well into the night.
