Theres a high or ridge to the east of our depression, the bermuda high and a trough in the gulf. Thats what all the dry air over the gulf is from. the models continue to show this trough backing west and the ridge sliding into eastern gulf this weekend. A ridge over a storm is a good thing(if you want to call it that) it helps in ventilating the storm, so intensification can take place. So to answer your questions, high pressure over a storm is a plus for development. Remember no dumb questions. Were all learning. Im sure a pro could correct me if Im wrong though, it can be pretty complicated. Have a good night.
