Annual Spring Forecasting Experiments (SFEs) in the Hazardous Weather Testbed (HWT) are conducted each spring, and bring together forecasters, researchers, and model developers from around the world in a simulated forecasting environment. The primary goals of the SFEs are to accelerate the transfer of promising new tools from research to operations, to inspire new initiatives for operationally relevant research, and to identify and document sensitivities and the performance of state-of-the-art convection-allowing experimental modeling systems (CAMs). A very large suite of experimental CAM guidance contributed by our collaborators has been central to the generation of experimental severe weather outlooks and model evaluation activities in recent years. During 2016-18, these contributions have been coordinated into a single ensemble framework called the Community Leveraged Unified Ensemble (CLUE). This talk will describe the experiments made possible by the CLUE framework, and recent objective and subjective results from SFEs.
