18z Euro AIFS is farther west with Melissa. I think this is the lowest pressure I've ever seen on the AIFS.

Over the past 30 days, Brazil #soybean regions have been substantially dry, with prod-wghtd precip only 82% of nrml. The 14-day AIFS, ECMWF, & GEFS fcst below nrml #Brazil soybean prod wghtd precip.

AIFS: 73% of nrml
ECMWF: 82% of nrml
GEFS: 63% of nrml

Uncertainty is high, but with only two to three days to prepare we must consider the potential for a tropical cyclone hitting Hispaniola this week. Sixty percent of models this morning indicate this. See DeepMind AI (FNV3), American GFS, European AI (AIFS), and US Navy. 1/

Since the default GEFS tracks from the NHC server continue to struggle identifying ensemble tracks for invest 98L, I swapped it for my in-house tracker that I use for the ICON & AIFS ensembles on my website:

My latest changes in the website were more "under the hood" - I revamped the tracking algorithm to better capture tropical waves before they become tropical cyclones, which is applied to both AIFS and ICON ensembles.
October 19, 2025 at 1:04 AM
Technical note — neither ICON nor the AIFS had many members identify Tropical Storm Lorenzo with my strictly MSLP-based algorithm, so I switched to a 10m vorticity & MSLP tracking algorithm. This now picks up much more members than the previous method.

Your next thought might be to look at AI weather models, since those have certain advantages over NWP models.

But even they are experiencing the same whiplash - notice how the AIFS over the last few runs keeps alternating between cutoff & no cutoff low in the Great Lakes:

Mistakes happen - my ECMWF ensemble data feed accidentally replaced the AIFS ensemble data last night. This has now been fixed & I backfilled all AIFS ensemble & deterministic plots back to 10/4.

The GFS, Euro and Euro AIFS are in good agreement regarding the east coast storm potential for this weekend. While it will likely be non-tropical (hence no mention in the NHC outlook), it will effectively have tropical storm conditions along the Carolina coast.

The 12z Euro AIFS continues to bring the system up the east coast this weekend.

Continuing down my tropical website checklist, AIFS ensemble tracks are now available on my website where storms can be identified & tracked in the model data.

Scroll over to the "Ensembles" tab for each storm to view AIFS ensemble maps if available:

An interesting artifact of some AI emulator models I just noticed - the AIFS seems to leave a "trail" of lower MSLP and geopotential heights in the wake of Hurricane Humberto's track, which lingers at those gridpoints long after the storm has passed:

Partly since I’m short on free time to do these all at once, and partly out of an interest in user feedback, I’ll put this out as a poll — what feature should I add to my tropical realtime site next?

1) full superensemble viewer
2) AIFS ensemble tracks
3) recon data viewer

The 0z Euro AIFS has #94L just off the Florida coast next week while #93L is off the Carolina coast.
September 24, 2025 at 12:04 PM
So the models seem to think there may be a tropical cyclone or two in the Atlantic this coming week.

12z Euro AIFS ensembles are continuing to show development chances in both the NW Caribbean and SW Atlantic.

🌡La très nette hausse de la température de la masse d'air à Paris (jusqu'à 20 °C à 850 hPa) devrait être suivie d'une chute probablement spectaculaire en début de semaine prochaine avec 15 °C de moins et un temps passagèrement pluvieux. C'est ce qu'indique en tout cas l'ensemble AIFS @ecmwf.int

Its not the first time models teased this but now may be the time for a substantial #cyclone in the Australian region. EPS in particular has near unanimous support and all major global models + AIFS are on board. Currently not really expecting a landfall but we will see #tropicswx
