Bob... Ike is not coming to your area. There is no model that shows it coming there and its almost impossible for it to move NW into a ridge. IKE is a GOM event with the Keys having a 40% chance.
The Gulfstream flight really doesnt matter much cause All the models agree on a west path across or near Cuba and into the SE Gulf somewhere. Its not like 1 or 2 models dont show this and the NHC wants that data to see which model is right. Also like Thunderbird said, its only for a short term (24-36hr) movement cause condtions change, thats why another flight is the next day.
