The European Storm Forecast Experiment issued a Level 3 which means there could potentially be a major severe thunderstorm outbreak.

While the first tornado was occurring, the main tornado-producer produced its first tornado, a large and violent multiple-vortex that struck the villages of Dolnica, Kopanina, Zimna Wódka, Kolonia Jaryszów, Balcarzowice, Błotnica Strzelecka and Dąbrówka with a total path of 20 km damaging or destroying hundreds of buildings and wounding 15 people, with a width of 500–1000 m before dissipating in a wooded area.

At 16:40 UTC the same supercell produced another multiple-vortex and non-fully condensed [3] F3 which struck the west part of Radomsko, destroying or damaging about 100 houses on a path of about 4–5 km.

The wedge tornado changed direction pointing to the south side of the city of Zimna Wódka, where 15–20 buildings were damaged or destroyed.

Crossing the highway, the tornado struck Sieroniowice and Balcarzowice where many buildings were almost razed to the ground (F4–T8 damage) and some people were injured.

The second tornado from the main tornado-producing supercell formed near Piłka and then struck the north side of the town at 15:30 UTC, producing little damage.

The tornado continued to quickly intensify and expand as it moved northeast of Rusinowice, where it snapped, uprooted, and debarked hundreds of trees in a forest.

The tornado reached its maximum width of at least half a mile north of Ciesnowia, clipping the northern side of town and leveling entire swaths of forest, denuding and debarking hundreds of trees.
