Every run will be different especially if you're talking 10+ days out. I am just looking for trends and all signs point to much stronger ridging then we've been seeing so far this month. We shall see if it is able to lock in more, timing is always crucial when it comes to land falling systems as well.



Ninel is making a good point here. Early month GFS runs were suggesting NE US ridging locking in and dominating 9/15-22. Since then, there has been plenty of delay and now they're hedging on NE ridging taking over even during late month. As a result, the 0z-12Z GFS runs of today dropped the late Sep. SE US cyclone threat. Let's see if the modeled threat returns.[/quote]

true, and im far from impressed about how the euro says oct will be favorable for east gom. east coast landfalls. winter like pattern is setting up and the ridge just keeps getting delayed. pattern persistence says not going to happen.

Was any data used to make any those predictions? I agree with the results, but I could have said the same thing 2 months ago and then claimed I was right because it came true.

That does not make me correct, it means I guessed correctly. I get no satisfaction from making correct guesses.

So why are you unimpressed? Are you simply taking a persistent pattern and figuring it will probably continue? If so, why? And if you know why, then what would it take to break the pattern?

If any of those answers are 'I don't know' then hey, that's ok, but you have to come right out and admit it's a guess.

I can't post the link from Alan's site but the 12z Euro shows another low pressue developing in the BOC and starting to move eastward by 240 hrs. Shows up much better on the vorticity image than here if someone has a free image to share. Could be something to watch...

It actually looks like some of the energy from Ingrid is left behind (which the GFS ensemble has been hinting at for last few days). This leftover energy looks to lead to additional mischief. The Gulf looks to be the place to watch for the next couple of weeks.

The GFS has been showing systems forming in the NW Caribbean and tracking NE out into the open Atlantic or up the East Coast off and on for about the past week.

the 0zGFS shows at hr 204 a low forming north of Houndoras and slides it up to the Florida straits at 240 as a strung out wave so this is an area that needs to be watched the next week to 10 days

Hurricaneman, that would seem to jive with Joe Bastardi's tweet yesterday about the Brazilian meteogram showing low pressure near Miami around that time.

Another look at the 12Z ECMWF:

A rather strange track with this one. The GFS has been showing the area getting going further south in the NW Caribbean and tracking NE:

216 hours:
Image

240 hours:
Image

12Z GFS 240 hours take it through the FL Straits and into the Bahamas:

Once again the ridge would be what would send this NE then ENE?

Overall pattern is going to change how? Is the ridge going to hold firm?

No not really. It looks like it takes it across SW Florida and off shore the East Central Florida coast.
