The FV3 is much, much, much worse than the old GFS. Their press release was a lie.
Found this link from someone else
https://www.weather.gov/media/notificat ... _v15_1.pdf It details some of the current improvements and what needs to be improved with the model.
The biggest thing with the Fv3 was definitely the cold bias and fantasy snows it would inflate. This is something they are currently attempting to fix. In my opinion this is the only area where the Fv3 is much weaker than the old GFS and once that's fixed the new model will be much improved. I believe we already seen signs the past couple of tropical seasons where the Fv3 wouldn't spin up some of the phantom storms the GFS liked to spin up, that would be a welcomed improvement.
