The 6z Icon keeps the track inland through PA NY and NE. This would mean a lot more impact for the Mid Atlantic and New England.
Also note that both the gfs and Icon both handle the NS differently on their 6z runs and show an amped up troff over the great lakes, which allows for this track.
Results in a much stronger landfall.
Edit: Actually only slightly stronger. But further offshore track should in theory give it a lot more time to reorganize.
Bizarre complex track shown by the GFS and CMC. The troff lifts out and the 250mb flow shifts to the NW due to the ridge over the Central US. Then a tutt forms over FL while a ridge builds over the Carolinas, shifting 250mb winds back to the ESE forcing forcing the storm back to the west.
Almost a 180 degree shift in the 250mb winds between hr 60 and 102
Kind of a broad circulation and there will be some shear in the northern Gulf. It's hitting a pretty storm surge prone area though. Luckily not very populated.
