This page displays comparison graphics in support of the official evaluation of the High Resolution Ensemble Forecast (HREF) version 3. The HREFv3 Official Evaluation is scheduled for May-June 2020.
The High Resolution Ensemble Forecast (HREF) aggregates existing high-resolution model runs and produces ensemble products (e.g., means, probabilities, etc.) for a number of parameters covering aviation, precipitation, severe storm, winter weather, and general forecasting applications. With the implementation of HREFv3, EMC is proposing to replace the operational HiResW NMMB member with the parallel HiResW FV3.
The HiResW FV3 realtime parallels being run at NCEP/EMC are compared to their respective HiResW NMMB operational counterparts.
