18z GFS at hour 84:
Also here is what wxman57 posted on another forum:
Been busy all day with a lot of things, one of them trying to figure out what the remnant low will do early next week. Seems like each model has a different solution, and a different solution with each model run. Hard to trust anything at this point. As weak as the LLC is now, there may not be an LLC in another 24 hours. Then all we'll have is an area of vorticity that eventually moves down near the coast (or just offshore). It would take longer for something without an LLC to develop.
GFS develops the low near the NW FL panhandle and tracks it just inland to Vermilion Bay then across the Gulf to Galveston, developing it very quickly offshore. Probably an unlikely solution. Euro is much weaker with the low. Can't get a closed isobar unless I go down to 1/2 millibar increments. But that may not be a bad solution. Canadian has been wildly swinging back and forth with its projections of where the low would go - west one run, east the next. Hard to trust that THIS run it's correct. NAM is ... the NAM. Develops most features, clueless as to where they might track.
Big picture would suggest a stronger ridge building north of the remnants, indicating a slow westward movement similar to the Euro. But does it get far enough offshore to give it a chance at redevelopment? Maybe. Something to keep an eye on, anyway.
Edit to add that the 18z GFS run doesn't ever get Ex TD 5 into the gulf but has it loop around the Southern gulf coast states before getting pushed north.
Also FWIW the 18z Nam does bring the low back into the gulf briefly:
