I just figured out why Trump wouldn't let go of the AL threat from Dorian. It is the UKMET's fault. Keep in mind that he is not a fan of the FV3. Remember those long delays for the FV3 implementation due to the govt. shutdown? As I said then, Trump wanted the govt shutdown for one and only one reason: to delay the FV3 as long as possible since he hated that model. He wanted the GFS Legacy to remain operational like so many of us here wanted due to the FV3 strong cold bias and other problems. Well, he delayed it as long as possible. Once the FV3 finally became operational, he decided he could no longer support the American model. As a result, he needed to find another model to be his model of choice. That model turned out to be the UKMET.
What does this have to do with Alabamagate? Remember the UKMET's stubbornness in continuing to take Dorian out into the Gulf and headed toward AL even when other models were well to the right over FL and east? End of story.
