That's definittely a trough, associated with Ivan, that you can see dangling in front of Jeanne, which will be responsible for edging her north before the high swoops downand loops her back. It doesn't show up on all the models, but I'd also assume that's a trough rolling away from Jeanne towards Karl. Most of the models show Karl turning north from the interaction with a large high north and east of Karl off Europe, as well as with the general rotation of Jeanne.

I'm still quite new to this, but that's what I gathered from watching the model loops.
