Survey of convective supercell in Slovenia with validation of operational model forecasts

The article presents the analysis of a severe convective storm in the Ljubljana basin in Slovenia. It includes special analysis of the development of the supercell made by C-band Doppler radar where all the typical characteristics of a supercell development can be seen. The forecasts of the ECMWF and ALADIN operational models were good enough to capture the area and timing of convective development. In Slovenia, a modified Showalter index is applied that improved forecasting of the occurrence of convection.
