Anything the ops and ensembles show after day 4 is nonsense
They are trying to link up the SE ridge with the developing block because they dump the trough out west after day 4.
However the ensemble trend has been to shift the western low further west and develop a ridge in the Rockies in the day 3-4 timeframe.
That trend will continue which will force the PV to move further S&E, not NW like models show.
