First post for me, but must have a say on how I think the gfs (and to a certain extent the ECM) are over playing a split jet to occur around the 72-96 hour mark (can't post charts on phone) surely the piece of jet shown to to go north of Iceland is going against the ssw affect, of reverse zonal winds around the periphery of the arctic circle, or has the ssw begun to subside and I'm missing something?
Just my thoughts on the pattern emerging!!!
I for one feel the plausible solution would be for a more powerful nw/se flow to the jet coming out of the eastern sea board hence undercutting potential around 120-144 to occur al a ukmo/gem and the ever more reliable CMA!!
Just a thought from me!!
Thanks
