Model

What

When

Short-range Ensemble Forecast (SREF) system Drop WRF-NMM members; increase total membership to 26 (13 NEMS-NMMB, 13 WRF-ARW); increase from 35 to 40 vertical levels; more physics diversity and stochastic physics parameters; use bred vectors and global EnKF to perturb initial conditions Spring 2015
High-resolution Window (Hiresw) system Increase number of vertical levels from 40 to 50; assorted post-processing changes/additions, including improved aviation weather products Spring 2015
Rapid Refresh/HRRR RAP version 3, HRRR version 2, content TBD Summer 2015
North American Mesoscale (NAM) System Initial implementation of NAM Rapid Refresh (NAMRR); Alaska/CONUS nests move to 3 km resolution; analysis/physics upgrades (TBD) Winter 2015-2016
RTMA/URMA system Nonlinear quality controlm additional analysis variables (wave height, ceiling height, SLP, maximum/minimum temperature Winter 2015-2016
