Looking at the upper features it looks like the wild card is the phasing with the ns.
Now I don’t know if there’s actually any truth in the old adage that the ns is more difficult to model because of data, but even if that isn’t true I would think this is a very volatile setup that could set us up for wild swings. Obviously I haven’t seen the 12z ens but the 6z had this storm widespread on the members. I’d say confidence in the storm is high but where is low.
