Just my 2-cents, but way too much emphasis on every tiny track or intensity change on every 6 hour model run. Not enough emphasis on the trends of the strength and physical layout of the west Atl. ridge to Henri's north and east, as well as the behavior of the OV upper level trough. Henri does not exist in a vacuum. It will only go where other large-scale features allow it to go. Closely monitor the position and changes & pressure tendencies of the Atlantic ridge's isobaric pattern. You have to continually ask yourself, does the modeled track make sense given the layout of the large-scale surface and upper air pressure / height pattern.
