Can you elaborate? I haven't seen anything more than a stray ECWMF ensemble or two bring it that far south...

Looks close to the GFS at 24hrs


I'm predicting a radical run either OTS or into N Florida to SC... Seems when GFS produces a wild run the Euro follows suit...

Please don't read too much into these historical plots, just doing it as a curiosity. Estimated Euro positions.

48 hours, 25.6, -54.0

They all start with the same data. And if it's garbage in, you'll get garbage out. I think the last two days of completely unexpected rapid intensification when the models and the NHC expected weakening emphasize this well.

It seems for now that the issue is the angle or set up of the ridge that ends up forming over Florence. If the setup is East to West, then that should favor a track into the mid Atlantic states imo. GFS seems to think the ridge will push it more NW towards the NE states with a NW-to-SE angle. For now I think the realm of possibilities are within that range (from mid-Atlantic states to NE states/POSSIBLE OTS scenario).

Looks just S of W from 24 - 72 hrs...

12z looks slower than previous runs, let's see how that impacts longterm track?

Should see the west to wsw turn in the next 6 to 10 hours with florence if it happens before 25N could see a subtle shift in the models next run.

The other big thing is models have for some reason a seriously hard time too quickly turning back wnw or nw after a SW dip. multiple examples. Almost every time this happens.

While we bicker on where Flo will go, I just want to give a shout out to NHC - that's who we REALLY need to be paying attention..

From their Discussion on Sep 1st 5am their 120 hour (5 day) forecast point was 23.5N 48.5W @ 65 MPH
Actual 5AM position this mornig: 24.1N 47.9W @ 115 MPH

While off on intensity (and I believe there is no way Flo was @ 115mph this morning- probably a cat 1) their position is rather good - actually remarkable at under 60 mile error @ 5 days - Wow!

Go NHC!
