Jacob's main area of research is for the annual Hazardous Weather Testbed (HWT) Spring Forecasting Experiment (SFE). This involves work with critical R2O project and accessing the latest convection allowing models (CAM) for severe hazards. When not preparing for the SFE, Jacob's research involves improving severe hazard forecasts, CAM and CAM ensemble verification, and other verification work using MET/METplus. Additional research includes development of potential forecasting tools for SPC operations.
