ECMWF VS GFS At 168-Hours

Yet again the two models have dramatically different forecasts for the Southwest - both from 12 UTC this morning and valid at 168-hours (12 UTC on Friday the 30th). The ECMWF (above) forecasts a strong closed low over Arizona/Utah, while the GFS (below) has weaker, short-waves over Texas Panhandle and west of Salt Lake. The height differences in the forecasts are almost 200 m over central Arizona.
