The reality- at least it appears to be the case right now, is there are going to be multiple daughter vortices- probably 3, for awhile. And as modeled, one piece will be on our side. It is what it is, but I actually like it for now, and looking through the last couple GFS runs, you can see the TPV shedding off lobes, or smaller vortices, which rotate into the 50-50 region and produce/enhance lower pressure there towards day 15. Its a great mechanism IMO to keep lower heights in that region with blocking over top. The TPV a good feature to have around as long is it doesn't go bonkers and drop down to Toronto or something. Now, as things progress and if we do get a stout -AO/EPO/NAO then as PSU said, we probably wont need(or have at that point) a TPV in our part of the world.
