I'm not sure if the bolded is true or not, it might just be that the model nested view just got left behind over South America.

UKMET has been lagging behind the major globals. I never rule out the UK, Not until those ensembles start tightening up.

Hmmm, if these model runs verify this could be the great one of 2021. They are all showing bad outcomes for the GOM coast. :double:

No doubt there will be some pretty extreme EPS solutions given what the operational just put out.


Euro showing rapid intensification on approach as well it seems


yeah bc its traversing 32C water. Thats like roids for a Hurricane. I would get puffy also. :D

It seems to have been the best performer this season, so far.

o maybe its just slow to see the upper air dynamics 5 days from now. IDK....It has lagged before this season and has adjusted right the past 3-4 runs with 99L. I have seen the NHC lean out it also in the past. Just have to see next run.

Not sure how accurate this is, but the HWRF shows about 5 kts of shear over the center when it is approaching Galveston.

Sometimes it is in certain windows of time. Other times its' an extreme outlier that rarely verifies until it comes in line with the rest of the globals. We've seen this over the last several years. It has scored a couple of coups, but I think those are remembered more by people than when it's in outlier phase. FWIW, the JMA is similar to the UKMET in that it is more aimed at south Texas.

Or one of big ones in 2021, the Euro is hinting a strong Cape Verde system for the last several runs . . .

All observations are in Tecumseh, OK unless otherwise noted.

Winter posts are focused mainly for Oklahoma & Texas.

Take any of my forecasts with a grain of salt, refer to the NWS, SPC, and NHC for official information

I wouldn't be surprised if this starts a string of strong peak season hurricanes (similar to Harvey, Irma, Jose, Maria in 2017) considering the favorable environment and long-term TC development in the ensembles.

Irma was the big one the UK did well on, even when the others were calling for a S. Fl hit or east coast raker. However Irma was also a lot more developed than 99L is at the time.

It certainly feels like it has been a long while since we've seen such consistency and agreement from virtually all the models. Rarely do they agree that a storm 5 days+ will be so impactful.

It was. Ivan as well (Part 2). It's hit a few others too. But it's been woefully off so many times outside of 72 hours that it's hard to take say when it's more likely to be right.
