Re: ATL: INVEST 95L - Models
12z Euro develops this to a TD/Weak Storm range.

Re: ATL: INVEST 95L - Models
Certainly,95L has more support to be a named system than 93L.

ECMWF continues to show a Hurricane with lowest pressure down to 976 mbs at 12z run.

Re: ATL: TEN - Models
Two consecutive Euro runs showing a fairly strong system at days 9-10. I'm not buying it 100% but it's something to watch more than the models other failures, two of which were storms that weren't even projected to form until day 5-6, the other being Erika which everyone got wrong.

Can you (or anyone else that understands) expand on what you mean by that, because you lost me, and I'd like to better understand what you mean by convective schemes.

Happened with Jimena. GFS and the Euro initially ignored the 50kt shear in its path and kept forecasting a hurricane near Hawaii.

18z looks so far to be coming back down to reality after being off in it's own fantasy world for a few runs. This El Niño just won't let it's grip up one bit!

In a surprising twist, the weakening may lead to conus impacts down the road.

Yeah at 150hrs. it is a very weak 1012mb low weakening fast I assume.
Man, this Record Strong El Niño is killing the fun!

Still more to come. The El Nino is peaking or has peaked, take your pick, and the season will continue... IMHO.

I don't see any indication that El Nino has peaked, in all likelihood it'll continue strengthening until winter.
As far as Ida goes (or anything tropical at all) I think the models are basically 100% useless, this'll be the fourth major the Euro has shown that doesn't even make hurricane.

Amazing to see these flaws coming out now. Thanks for insight. I would say we will see a good shift west again tomorrow. Center is racing west tonight.

I wouldn't say useless but I know what you mean. They have been quite awful this year but I do feel the GFS has improved since last year so at least a step forward there, while the ECMWF has taken a step back.

I just don't think the models have ever had to deal with such harsh conditions in the Atlantic like the last few years. Record dry air and record shear which are notorious difficult to forecast have wrecked havoc on the models. At some point you have to accept the limitations. We got spoiled years back when the models verified quite well during normal years.
