Big differences between this and the previous GFS run. Not to worry about I suppose now that the models have begun to trend towards the ECM. And STEVE was correct to say a day ago. GFS 8-10 runs will do what it has done so far. Trend towards the ECM. Even though after T144 it loses the heights on this run.
Edit; spoke to soon, It is a late horse run. Gets there at the end and probably about to deliver a eye candy fi.
