The remainder of the presentation will focus on ongoing ensemble work, including a description of the HRRR Ensemble (HRRRE) system that has been running in a real-time experimental configuration for several months and been evaluated in several different testbed programs. The real-time HRRRE includes a 36-mumber storm-scale ensemble DA system, which is used to initialize a 9-member storm-scale ensemble forecast system and has also been used as part of the initialization for a parallel deterministic HRRR. A number of scientific issues will be discussed, including benefits of the storm-sale ensemble DA to both the ensemble and deterministic forecast systems, use of stochastic physics and other techniques to increase ensemble spread, and work to obtain the optimal blend of storm-scale and larger-scale spread information. Finally, ongoing work to develop an ensemble post-processing system will be described. This system is being designed for use with different models and ensembles (including time-lagged ensembles), and will provide bias correction, member aggregation, and generation of reliable probabilistic information, as well as other ensemble guidance information. This work has also included obtaining feedback from forecasters on use of the ensemble-based products and recommendations for improving them.
