...HRCN WILMA...
VRY POOR MDL CONSISTENCY WITH WILDLY VARYING SOLNS SEEN IN THE 12Z
GLOBAL MDL SUITE. THE OVERALL TREND OF A SLOWER MOVING HRCN WILMA
SEEMS REALISTIC GIVEN SHRT TERM TRENDS SEEN IN SATELLITE IMAGERY.
THE MAIN PROBLEM CONTINUE TO BE THE POINT AT WHICH THE STG HEIGHT
FALLS OVR THE E CTRL U.S. PULL THE STORM POLEWARD. THERE HAS BEEN
A TREND WWD IN THE 12Z UKMET/GFS AND NAM SOLNS...BUT THESE MDLS
DIFFER WITH THEIR TIMING. THE 12Z CMC SOLN IS FARTHER TO THE RIGHT
AND A LITTLE FASTER. PLS SEE LATEST NHC DISC FOR MORE INFORMATION
ON WILMA."

...Still, something doesn't seem right about this 12z variant... I just think it's ultimately going to come down to an as yet determine meridianal depth of the trough centered on 80+W, when that finally occurs.. so I agree with them that much. As far as the GFDL interacting with the landmass of NE Coast of Yucatan - this is the first run that has had this behavior and has virtually no support from previous guidance suites - at least, not that far inland..
