The next (0z) model runs (some of the early cycles will be out soon, and late cycles starting around 11:30) have some the Gulfstream IV data in them. Special Balloon launches are starting tomorrow as well, so there will be a good deal more data points for the models and hurricane center tomorrow. The "center" mentioned above probably will change again, last night I said the northern one looked more healthy, and it wound up being the opposite.
