Polarimetric radar technology is expected to emerge into operational forecasting during the next few years. NSSL's Warning Decision Support System - Integrated Information (WDSS-II) is being used to develop and test polarimetric radar applications. These include fuzzy logic membership functions for automated hydrometeor classification, melting layer identification methods, and procedures for classification of surface precipitation type. WDSS-II also allows the integration of data from other systems, such as numerical model and surface observational data, to enhance algorithm performance. The design of these test and evaluation procedures is described, including case studies. Implications for operational implementation are discussed.
