Firstly, the QPF of rainfalls from convective period in 2009 was verified before and after the ALADIN CZ modifi- cation. In June and July 2009, convective rainfalls with the return period of more than 100 years caused devastating flash floods in many Czech localities. In the second part, the results of the verification analysis are presented for the operational QPF produced by the modified ALADIN-CZ. We verified the summer period 2013 which includes the 2013 flood in the central Europe. The verification analysis considers the influence of (i) convective forcing, (ii) the area extent and duration of the convective events, (iv) threshold precipitation, and (iv) forecast lead time. We conclude with the discussion what intelligible user-oriented information about the QPF skill follows from the verification.
