An overview of the current NCEP short range ensemble forecasting (SREF) system that includes breeding initilaization, member configuration, postprocessed products and ensemble based verification tools, was presented. Some of the findings from a comparison study between a multi-IC and multi-physics ensemble approach for short range forecasts, were reported. The preliminary results show that adding physics diversity improves the SREF system's ability to capture more forecast uncertainty. This SREF system product directly supports NCEP's strategic goal of delivering improved probabilistic products and services.
