    Forecast uncertainty is an inherent part of high-resolution quantitative precipitation forecast (QPF) and it is particularly pronounced when predicting heavy convective precipitation. Ensemble prediction is a usefull mean to assess the QPF uncertainty by employing ensemble spread that characterizes differences between the control forecast and forecasts provided by each ensemble member. In this study, we used gauge adjusted radar-based rainfalls in the QPF verification and we applied Fractions Skill Score (FSS) in the calculation of the ensemble skill and ensemble spread.
