And this was the commentary from NCEP on Friday when the GFS started showing this
GFS HAS TRENDED TOWARD A STRANGE SPLITTING OF MID AND LOW LEVEL
VORTICITY WITH SYSTEM...ALLOWING A NEWD PROGRESSION AT H8 LIKE THE
00Z/22 RUN...BUT DIVIDING THE H5 ENERGY AROUND F27 ON THE NEW RUN.
GFS VERY SUSPECT WITH BOTH ITS DECOUPLING OF THIS SYSTEMS MID AND
LOW LEVEL VORTICITY...AS WELL AS ITS ODD DIVISION OF THE H5
ENERGY. WHAT MAKES THE DIVISION OF THE H5 VORTICITY ODD IS THAT
THE GREATER MASS OF ENERGY IS ACTUALLY LEFT BEHIND THE TROPICAL
SYSTEM...WHICH TRUCKS NEWD ON ITS MERRY WAY INTO OPEN ATL.
NAM IS CLOSEST TO THE OFFICIAL TPC TRACK OF SYSTEM AND IS
RECOMMENDED OVER DUBIOUS GFS.
