A notable change from the Euro this run is the eastern US trough. It does not dig as far south as previous runs, so it's more like the other models now in that regard. As someone posted yesterday, that trough will be pulling a bunch of dry air down into the southeast US and Gulf of Mexico. This run of the Euro gets farther north before landfall and, over the last 18 hours before landfall, has the storm rapidly weakening from 939 mb to 970 mb because of increasing shear and a big gulp of dry air.
