18z GFS vs 0z ICON, and to me the ICON looks better at h5. if the GFS can spit out 6-12" with that look then it would definitely spit out at least that with the ICON look
The fact that the euro runs at 2.5x of the GFS might help it detect things the GFS isn't seeing, but I would agree with the fact that we won't know much until 72 hours or less.
