Forecasting, locally, heavy convective precipitation events has been an important topic of investigation for a few decades. It has been recognized that nonhydrostatic models are able to simulate the dynamics of organized convective systems with spatial resolutions of 1 km and less, provided that adequate triggering is entered in the model. Apart from experimental model runs, there are also diagnostic case studies of convective events that employ such models and compare the results with radar data, for example. Nevertheless the purely deterministic prediction of severe convective systems and corresponding quatitative precipitation forecast (QPF) is far from being resolved.A research project, focused on case studies of severe convective events in the region of the Czech Republic (CR), has been running since 2000. Data from this study have been used to adapt the nonhydrostatic weather prediction (NWP) Local Model of the German Weather Service (LM DWD) to use a 2.8-km horizontal resolution Small Local Model (SLM) for forecasting and/or warning of severe convection events. The results of several model applications are summarized and discussed.
