University of Washington Mesoscale Ensemble
Multiple 48-hour forecasts of U.S. Pacific Northwest weather by the non-hydrostatic Penn State/NCAR mesoscale model (MM5) are produced twice per day at the University of Washington. MM5 is a research oriented numerical weather prediction model, maintained by the National Center for Atmospheric Research, Mesoscale and Microscale Meteorology Division (NCAR/MMM).
