It also had higher heights south and southeast of the ULL for what that might contribute to steering.
Yeah, it does seem the Euro has a more compact ULL that perturbs the ridging north of Irma a little less than the GFS, even though the two have converged on position.
This is one of those setups where the geometry of the ridge >>> the strength of the ridge.
