Funny thing is, gfs keeps doubling down even slight improvements each run....but its not like other guidance is trending bigly the other way. There has been very slow/subtle shifts across other guidance even giving a slight nod to the GFS. I dont think the GFS is 100% accurate by any means, but a 6hr change in timing of the shortwave in question on other guidance and boom the GFS suddenly has legs. We'll see. Being a betting man Im putting the mortgage on the gfs being the outlier though.
