Hey...the GFS
I hate to be the one to post this...because...it is the GFS model afterall. But I don't think I am the only one who is noticing the development of a monster ridge in the 500MB layer with this model.
Check out the 72 hour pattern in the 500MB layer:
http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_072m.gif
Heck in 2 days there is a huge ridge in the western Atlantic:
http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_048m.gif
The weak 850MB reflection of Irene in the model gets pushed back to the west then SW in the GFS solution....compare the 48 hour position (little yellow blob) to the 72 hour:
http://www.nco.ncep.noaa.gov/pmb/nwprod ... v_048m.gif
and
http://www.nco.ncep.noaa.gov/pmb/nwprod ... v_072m.gif
Not much of a system in the model...but a monster ridge to the N.
NOGAPS appears to be a bit further north by day 4 so hard to get too worked up by the GFS solution...but this going out to sea scenario seems less likey than it did a day ago...to me.

1) Irene will already be in the center of that dome. She'll run right through it poleward.
2) If Irene is south enough it will track slightly WSW in reaction.
3) If Irene hasn't hit it yet she could radically recurve north in reaction.
I really don't see 1 or 3 panning out, ever...but oh well.

Amen to that. No matter what happens, SOMEONE'S forecast is going to be dreadfully wrong, looking back 5 days from today. Hehe.
I agree, theres going to be alot of crow being handed out for Irene

>>I was told by about everyone here... the GFS is far superior in recognizing and ridges than anyother model..
You never heard that from me. I'd go with the European or hell, even the Canadian Ensembles (though not the operational model) before I'd go with the GFS. The GFS sometimes catches the pattern at different heights though to be fair.

Now how it handles a TC is another story
Many of us (including Steve above) have been saying for a week now not to trust the GFS with Irene. It's had a hard time with the ridge and heat in the east all summer, there are some very well-known biases with the GFS but for some reason people keep driving off the cliff with it.

Because it's "on to something" when it depicts what they want to see and "on something" when it doesn't?

this whole statement in the 11am advisory has me really concerned now
A
SHORTWAVE TROUGH CURRENTLY ALONG THE U.S. EAST COAST IS GRADUALLY
LIFTING OUT TO THE EAST-NORTHEAST...WHICH SHOULD ALLOW THE BERMUDA
MID-LEVEL RIDGE TO BUILD NORTH AND WESTWARD INTO THE CAROLINAS IN
THE SHORT TERM...WHICH SHOULD KEEP IRENE MOVING WEST-NORTHWESTWARD.
THE OFFICIAL FORECAST TRACK LEANS MORE TOWARD THE GFDL AND GFDN
SOLUTIONS...AND REMAINS CLOSE TO THE PREVIOUS FORECAST TRACK AND
THE LEFT SIDE OF THE MODEL GUIDANCE...GIVEN THAT THE UPSTREAM
SHORTWAVE TROUGH OVER THE CENTRAL U.S. IS RATHER WEAK AND
UNIMPRESSIVE AND MAY NOT WEAKEN THE RIDGE ALONG THE SOUTHEAST U.S.
COAST AS MUCH AS THE NOGAPS...UKMET...AND ECMWF MODELS SUGGEST
If that ridge builds over the carolinas and the trough isn't as strong that north curve will be much more gradual and more WNW to NW than what they are predicted so SC/NC are really going to be under the gun next week

And it is moving 17MPH so that may hold true
