Re: ATL: INVEST 99L - Models
OK so 12 Z GFS seems to take this and pull it though the Mona passage at 120-ish hours and it gets pulled into Jerry's circulation and slingshots around leaving Jerry's vortex behind which remains closed and starts to move SW under a major 594 mb high across east CONUS.....Bet this thread lights up Sunday night if this starts to verify

EDIT: Actually just saw the 12Z GFS run and indeed Jerry actually gets left behind and gets grabbed by the ridge late in the period.

NEVER, EVER SAY NEVER in the tropics and weather in general, and most importantly, with life itself!!

Re: ATL: INVEST 99L - Models
Euro for the first time has it better but dies south of PR. The rain is the main concern for the islands.

Re: ATL: INVEST 99L - Models
Meant to post these earlier (12 Zulu) but good thing I didn't an hour or two ago as the models have really filed in for 12Z since I last checked. Last time there were only about four of five! Consensus line has thus shifted dramatically (before it was plowing right into FL)
Here's a VMAX as well with all the same models. I know the EPS isn't here but as soon as it's visible I can get it.
Source if you'd like to view these on your own (great resource imho): http://www.hfip.org/nhc-display/#
And this one will show the EPS and EPS BUFR actually, too. The Google Maps API is a tad ugly but it's workable! https://ruc.noaa.gov/tracks/

12Z EPS from a kind of wide angle also showing Jerry - and a poorly-edited one as well with a couple of other models thrown in. Not too important what they are as they're barely on there.

18Z Track and VMAX Guidance from the source 2 posts up.
What in the world is going on with the CONS? Maybe a poorly-configured algo'.
Recurving even harder than before.

I'd love to see what kind of weird mechanisms would cause a track like that.

As long as it doesn't want to do a circular loop anytime soon.

I hope we don't get any sort of a Maria repeat out of this one.

I am not a meteorologist, and any posts made by me are not official forecasts or to be interpreted as being intelligent. These posts are just my opinions and are probably silly opinions.

Re: ATL: INVEST 99L - Models
Hmm looks like a different twist on track thinking from the 12Z GFS FV3 and legacy models with a turn to the west and SW once it is north of the Caribbean. The FV3 brings it back down into the Northern Caribbean heading towards Cuba.

Yeah seems like a subtle shift to the models this morning. Instead of quickly sweeping 99L in Jerry's footsteps, looks like it's being left behind

Re: ATL: INVEST 99L - Models
12Z CMC also changes its track with a turn west east of the Bahamas. It’s not a storm but you can track the 850mb vorticity turning west with a big 500MB high building over the EC:

Maybe the direction change the CONS was trying to show wasn't that weird after all, then? The acceleration to Mach 3 or whatever from 168 to 192 hrs seems to be a little high to me, though...

New GFS also showing the same idea. That energy gets driven SW around what is apparently a ridge
