,,A line of supercells with reported tornadoes are ongoing across a line from just west of Warsaw to Krakow to Bratislava. These are expected to continue during the evening while moving eastward. As a southerly nocturnal low-level jet sets in across the Pannonian Plain and the Carpates, and the pressure gradient increases due to pressure falls east of the Alps, low-level shear profiles are expected to improve further. A continued threat of supercells producing (strong) tornadoes, very large hail and damaging winds is forecast. Storms may weaken no sooner than well after midnight.''
