What is interesting to note about tonight's run of the upgraded GFS is that it still shows a very strong trough (for late June) moving into the picture, but 93L seems to miss making the northeastward connection with the weakness this go around. Because 93L is positioned slightly further south and west on this run when the trough swings by (compared to the 18z), the system becomes stuck in the western GOM and eventually meanders into northern Mexico.
Comparison between 18z and 00z upgraded GFS runs for next Wed. morning..

so should we start having more confidence in the models now if the euro shows the same later tonight?

Re: ATL : INVEST 93L - MODELS
so it looks like we might be seeing a tex/mex landfall. does this scenario sound plausible to you guys?

for sure, i liked that idea three days ago and of course even more now, weak system with strong ridge

Yeah thats what I've been thinking as well, I think something close to the TX/MX border is likely at the moment. ECM suggests a TS right now.

Re: ATL : INVEST 93L - MODELS
Latest model plots - I noticed the BAMM has now shifted northward. GFDL and HWRF almost identical tracks.

Both the 00Z GFS (new model) and ECMWF show a system that heads into Mexico south of Brownsville. So does NOGAPS. At least we are seeing some consensus from the global models so I would say a BOC/Mexico solution seems quite possible (maybe likely) at this point. Perhaps extreme southern Texas may be impacted. IF that were to verify, great news for those in the GOM in the US and the oil spill area.

Re: ATL : INVEST 93L - MODELS
But of course the model runs can be thrown out the window if a depression forms later today and then some fairly quick strenthening takes place during the 24-48 hr timeframe before it reaches the yucatan. Also the NHC is saying 93L has staarted to move towrds to NW and will continue to do so. IMO biggest thing to watch for the is evolution and progression of the early summer trough that could make its way down south and how much it breaks the ridge down.

The one thing that is obvious looking at the mean motion is that steering currents have become weak which probably suggests that the models idea of a NW turn is not far off from happening.

Where do you NHC indicating "NW"? In the latest disco they indicate it is heading towards the Yucatan, that is WNW to W movement. Even if a depression forms later today the GFS and ECMWF have really started to agree on the evolution of this system, probably a TS into the WGOM if they are correct, and quite possibly a Southern Texas or Mexico landfall far away from the oil spill.

The NHC in thier latest statement said they expected the system to move NW towards Yucatan, due west/WNW would take it into Belize more then likely.
