Not a lot of convection but wave axis is around 50W chugging westnorthwest.

No wonder the models don’t develop this wave in the Caribbean. That is some ripping shear! :eek:

Yeah it's been pretty hostile for a while now. And SAL is making a huge push south right now too. I'll start worrying when I see wxman giving it more attention. So far, he's been saying a potential rainmaker, which for South Texas wouldn't be a bad thing.

If you think the 18Z GEFS uptick was impressive, check out the 0Z GEFS, which is loaded with TS+'s in the W GOM!

Yep, another decent uptick from the 18z GEFS.

The ensemble members seem to weaken the EPAC storm fairly quickly, which may be allowing a potential storm in the Gulf to flourish.

The operational was hinting at this as well, a quick spinup that gets further NW and weakens significantly. Also GEFS 500mb anomalies not displacing the subtropical high as far west (was displaced into the EGOM 5 runs ago):

Which could give a potential storm a lot more real estate to operate in that scenario.

It's important to note that the GFS Ensembles have not been upgraded the to FV3 core yet.

Didn't realize that, probably why there's discrepancy right now and why the ensembles were quite different during Barry.

Increased southeasterly flow along the southwest periphery of the ridge will enhance convergence as well.

Convection has increased.
