The lead time of the forecast is one and two hours, and the methods are applied to the warm season. The first method is based on a regression model while the second one uses neural networks to describe the relationships between predictors and predicted values. The predictors are derived from radar data and prognostic values of a NWP model. The results show that the forecast is quite succesfull in night and morning hours. On the contrary, in afternoon and early evening the accuracy is much lower as both the models are not able to properly predict convective precipitation Workplace Institute of Atmospheric Physics Contact Kateřina Adamovičová, adamovicova@ufa.cas.cz, Tel.: 272 016 012 ; Kateřina Potužníková, kaca@ufa.cas.cz, Tel.: 272 016 019 Year of Publishing 2005
