GFS Trend
Posted by CX on 9/2/2017, 6:16 pm
Personally, I am not the biggest GFS fan, but this is a graphic of how it is trending in the mid-term over the last few runs.



Note Irma's position has been slowly shifting S. the trough over the CONUS has been trending deeper, but it doesn't dig S as much. The strength and position of the highs don't change much, but the key is the trough. If the weakness closes before it can grab Irma, Irma will most definitely become trapped and will continue with some degree of a westerly component into land.
