I find a few problems with the GFS solution, and even the ECMWF, which is also showing tropical troubles by the end of the next 10 days. This ridge should die off by the time 8 days is up from now. After that 8 days, the negative PNA pattern will collapse and the trough will progress east into the central and eastern parts of the nation. This trough's movement east will push the jet stream south and thus drop tropical cyclone formation potential over the Caribbean and Atlantic areas. The timing is not matching up.
Climate models are projecting unfavorable conditions for tropical cyclone formation as well, with the CFS long range model hinting at strengthening upper level winds in the 10-15 day time frame, which would drastically hurt tropical cyclone formation chances.
