To answer you question, the NHC has had great reason to investigate and take interest in this location for possible development today. We had an upper level low that became vertically stacked to the surface. Since tropical systems are warm core surface features and ULL are cold core features at the upper levels...This stacking from top to bottom allowed for the possibility that the ULL could transition down to the surface and convert from a cold core system to a sutropical (Hybrid warm/cold core system) to one that was tropical and based at the surface. Overall, this type of transition takes a couple days to become fully complete, so it requires special circumstances over time to get the proper stacking and to make it last long enough.
When recon was tasked to fly out there, and everyone (including me...please see earlier posts on this thread) were more interested in this sytem...it was due to this stacking. That said, late afternoon, the ULL has moved off to the NE and the sufrace feature decoupled. They are not vertically ctacked any longer since the surface feature got left behind. The overall synopsis changes to an environment where the ULL is in control, and now has the potential to provide less than fovorable conditions. After the de-coupling takes place, a lotof energy is lost from one system or the other...When that happens, the ULL always wins.
