Not just the GFS. There has been a lot of talk recently on this forum about how bad the GFS has handled the current set up

ECM flipped a few days back and since then has retained a milder outlook from Thursday. It didn't flip back again, unlike GEFS (which then flipped back again afterwards).
MetO stuck with a colder, blocked outlook for longest. In the last day or so it too has flipped, but bear in mind we don't get to see the charts for the ensembles (MOGREPS) so we have no way of knowing what the clustering is like other than third-hand info.
MetO did the best overall IMO, then ECM and then GFS last - by quite a way. It's not a case of cherry-picking a run, either, that's based on the last week or so of model output.
After all, we're still looking at Thursday or Friday (on current models) before milder air sweeps across the UK. Bearing in mind MetO was insistent that it would be cold until then until the last couple of runs... it takes the prize IMO. ECM had Thursday as it's "mild sweep" day since it flipped and of course GFS has varied from today, tomorrow, then Monday... you get the idea.
