Could the GFS score a coup on this one, maybe, but it really just is a woeful model. The GFS holding on to a solution for run after run only to cave to other guidance in the short term is almost always what occurs. The verification scores show everything you need to know:
The Euro, CMC (can't believe I'm saying that) and the Ukmet consistently outperform the GFS.
Again, could the GFS be correct in this case, sure, but overall it is just not a serious model.
