12Z model guidance starting to come out. The GEM is maintaining a closed low now up through 174 hours the run is out too so far with a low tracking west across the MDR but very slowly. In the previous run it killed this low. It is trending closer to the ECMWF.
I can't really make out what the GFS is doing with this but it seems to develop some low behind this one while this invest becomes stretched out into a trough. Not sure I buy the GFS solution and will lean with the ECMWF/GEM.

Re: ATL: INVEST 94L - Models
Shear will be an issue but the sinking air ahead of it will the biggest issue even the models are saying that but if this goes N of the islands this may have a shot especially north of Puerto Rico next week if its still around

The GEM model has a low for the full 10 days now and does not poof it, though it moves incredibly slow through the MDR. It's a good sign the GEM is not poofing it because you know if the GEM doesn't show development it probably won't develop since it is usually so bullish. In the 00Z run, the GEM model poofed it.

whoa Cycloneye, the intensity models keep trending more intense. Interesting indeed.
00Z SHIPS is showing even less shear now for the next 5 days (bolded below):

Re: ATL: INVEST 94L - Models
The normally conservative UKmet has it through 72hrs then looses it.

IMO the UKMET has not been conservative at all this year.

Well historically it has been in the lower tier of false positives on cyclogensis when comparing the global models. See my link below. I don't know about this year's perfromance. Maybe you have some newer research you want to share or is that just your opinion.

Just my personal observation, but it's been more bullish lately.
