Is it just me or does the CIMSS 200-700 MB Layer Analysis show that the upper-low has had a slight southwestwards movement today? I could see that if this low moves farther south, it could "pull" Dean northwestwards more than anticipated. Maybe this is where the GFDL is getting its solution. Speaking of the GFDL in the 2100Z discussion, the NHC mentioned, "THERE COULD BE VERY UNCERTAIN DAYS AHEAD SINCE THE GFDL HAS HAD A VERY RELIABLE TRACK RECORD."
