Examples of new guidance products derived from the high resolution ensemble. The top figure shows the probability of a linear configuration of thunderstorms (e.g., a squall line), while the bottom depicts the area covered by cores of simulated radar reflectivity (> 40 dBZ), color coded to represent the different ensemble members.
