at the same time, i think the lack of retrogression on the GFS is due to the fact that it buries everything out west and you don’t have that final wave break
i think the GFS just buries it. doesn’t mean that it’s correct. even if it is correct, it just delays the cold air outbreak for a few days, it wouldn’t be disastrous or anything
definitely a trend to phase the kicker in earlier, leading to a much better PVA axis overhead. i'm inclined to believe the GFS is wrong, but this is worth watching
