Short-Range Ensemble Forecast (SREF)

The Storm Prediction Center (SPC) Short-Range Ensemble Forecast  is produced by postprocessing the 21 members NCEP SREF plus the operational WRF-NAM for a total of 22 members. Special emphasis is placed on high-impact, mesoscale guidance including winter weather.

NCEP SREF Plume Viewer

There are three different model families with one control member and three positive and negative perturbation for each control.

NOTE: This viewer should be considered EXPERIMENTAL and is not supported on a 24/7 basis.
