ECM and UKMO are pretty much identical at T144 while the GFS is no where near at the same time frame, you could either say in this instance then that T144 is FI or the GFS should be ignored?, personally I would go with the majority and say the ECM and UKMO are correct with the position of the high for the medium term. I think this ties in with the METO outlook stating cooler in the East of UK. Could be interesting developments with the Azores high in 8-10 days time as GFS shows ridging North at T216 and the ECM shows ridging at T240, one to watch maybe?, it's not the first time it's been shown on the runs either.
