ATL: ISAIAS - Models

[Evil Jeremy]

Can anyone point me in the right direction for a list of computer model run times? I tried the search bar but couldn't find anything.
Trying to set up some alarms on my phone so I'll know when to watch them roll in for this potential TC. Thank you.

I used to keep this info in my signature lol.

Roughly:
GFS: 5:30/11:30 AM and PM
ECMWF: 1:45 AM and PM
UKMET/HWRF/CMC/NAVGEM/ICON: 12-1/7-8 AM and PM

That’s when they start, takes up to an hour to get a full run done.

Ensembles roughly 90 min after operational run, IIRC.

Thank you. I usually memorize it over the season but then forget it come nov-may lol

I thought the Euro ran at 1:45 AM/PM?

The 18Z GFS continues to be bearish about this wave. Looks like a SAL surge from the east ultimately squashes this wave but there is a closed isobar now:

Yep 1:45 and Ukmet around 12:15 am

I made this chart a few seasons ago to keep track of all the times. Hopefully it helps someone

Which is why you can't completely dismiss the GFS. SAL is still a player in July, early August.

The GFS hasn't seen squat this entire month. But yeah, can't completely ignore.

And finally we see some GFS ensembles with development. A few look like they end up strong. Similar tracks to the EPS:

[AutoPenalti]

Yikes, the GFS really is playing catch up with the other models.

The GFS is finally waking up and smelling the roses! This model just can’t seem to latch onto anything this year. Yes it got Cristobal but that’s about it!

[Cpv17]

That’s scary if the GFS is actually seeing something

Every model (or their ensembles) are onboard at the current time.

[SFLcane]

Very high probability this becomes a TD 85-90%

Yeah and another one behind it.

18z NAVGEM is starting to agree with the Euro and ICON, and shows development within 5 days instead of over a week out.

[HurricaneFrances04]

The NAVGEM has been ATROCIOUS with Gonzalo, so I take its run with a grain of salt.

Oh it’s been absolutely terrible with it, but at least it’s on the same page as the Euro, ICON, UKMET, and JMA for 92L.

[CyclonicFury]

GFS might be starting to cave, it is showing a much more well defined vortex than previous runs.
