Re: 2018 Tropics: Global Model Runs Discussion (Out to day 16)
Well before the week 2 wackiness, all of the global models are forming a weak BI (baroclinically initiated) low near Florida in about a week.
It forms in association with a cutoff 500MB low.

@BigJoeBastardi
Was laughing before, not laughing any more at GFS longer term MJO forecasted through favorable phases, especially after day 10 ( phase 2) early activity next 10 days Pacific, then perhaps to Gulf, Caribbean or SW ATL day 10 on

The new FIV3-GFS model is making this quite strong. The FIV3-GFS starts development in 1 week near Nicaragua and sends it north. Hard to believe something like this forms in May, looks more like October. Gets down to 975MB at 246 hours

You gotta be kidding me, right? The new-GFS shows a full-blown hurricane in the Gulf in a week and a half. Talk about an improvement from the current GFS.

Yeah looks interesting, that should be the catalyst to start the rainy season I would think, good news in that it would start early reducing the length of the "fire season." Looks like the ECMWF has it passing just east of Florida while the GFS is in the Eastern Gulf.

I know it is very early in the season to be asking this question...but do you think this could be a major test for the FV3 implementation of the GFS? If this ends up being a phantom storm, then would it make the FV3 look very bad?

The FV3 has generally the same physics as the GFS operational, which would mean it's little help in the phantom department.

Actually, this FV3 run and the FV3 runs prior to it initialize a microlow in the 970s at CV and each run keeps it stationary the entire run!
Edit: Looking more closely, it has this right over the highest CV peak, Pico do Fogo, which is over 9,000 feet up:

This peak seems to be messing with the surface pressure.

IMO it will put in it the EPAC sooner or later.

In fact,it began with development in EPAC for a few runs. This was on May 4.

florida,
I agree that the East Pacific is favored but I will caution folks that IF there is El Nino coming (nobody knows), that actually would favor above normal chances for Gulf activity in June.
Of course, just one TC in the GOM in June would be above the normal.

FV3-GFS has it again where development starts in the SW Caribbean in about a week or so from now lifting north, 180 image below:

NAVGEM is on board, 1st non-GFS or GEFS model to show it. imo, it's more likely that this disturbance forms in the EPAC, but models like the SW Caribbean

Re: 2018 Tropics: Global Model Runs Discussion (Out to day 16)
I’m having doubts even with the slight increase in model support, it could be EPAC as well and with possible delays on timeframe with genesis.

Wow the FV3 GFS is going bonkers with this system:
Wasn't this model supposed to reduce phantom storms like this?

If I had to take a guess it looks like a potential convective feedback issues is going to be a MAJOR problem with this new-GFS. Correct me if I’m wrong, Alyono knows more about this.

Later, the crazy model strengthens it to 970 mb before going onshore and moving to just se of Ocala at 971 mb (hour 300 Sun eve 5/20)!
