The latest release of the model evaluation tools (MET*) software includes many new features. Verification of probabilistic forecasts is supported and includes appropriate statistics like the Brier score. Wavelet decompositions can be used to examine forecast performance at different spatial scales. User-defined polyline verification regions can be more efficiently defined and applied. The MET tools have been modified to enable more general comparisons between any two variable types. File preprocessing has been simplified, and the output statistics file format has been enhanced. The MET website has been updated to include a graphical user interface for producing configuration files used by the MET tools. Additional scripts to produce graphics have also been added to the MET website.

*MET is a freely-available forecast verification software package distributed through the Developmental Testbed Center (DTC) for testing and evaluation of the Weather Research and Forecasting (WRF) model.
