These systems don't phase, but if the NS gets ahead , it will crush the SS before it gets up the coast. So you should probably hope the SS doesn't slow down here, and the NS doesn't speed up. Either will lead to a weaker further south system.
It was really more a comment into the mechanics of the storm. We need the NS more amped up if it's going to come up the coast.
I really never trusted the NAM or RGEM on their own. Always worth waiting for the better models to come out.
GFS Para has the same performance score as the old GFS. This happens with every supposed "improvement" to the GFS physics and resolution. It's still just as wrong as the old GFS but in a different way.
Kind of reminds me of the Washington Football team. Whatever improvements they make they're still 6-10, they just win a different 6 games.
Euro has a gradient flow with a lot of potential for overrunning events. Models don't always see them until a couple days in advance. Euro attempts one Tuesday and one Friday,. These are the kind of events that pop out of nowhere in good patterns.
