Lol almost missed the fan .
To repeat years past, there is a break in the ridge projected by most models, question is, will Erin be strong enough at that time to catch the break or be weak and continue west.

The break is the same trough currently in the central US? It seems that will play a major role in the short term - and behind it, there is nothing.

Correct. Looking at the GFS 500mb heights and current surface analysis, the trough is currently in a blocking pattern, with high pressure in front and behind. Looks to be slow moving and eventually flattens out in ~150 hours.

Re: ATL: ERIN - Models
It's interesting how the models show it going NW when in reality, Erin would likely shoot off to the west as it weakens, so the NHC has the right idea.

That's how I see it. If the NHC intensity forecast is close to accurate, the overall pattern suggested by the GFS is a flattening out of the trough, and very weak steering ensuing. The GFS almost has some weak ridging in the past run.

Re: ATL: ERIN - Models
The offical track has Erin headed westward but the models go fish (lol) - but a TS at 15N and 25W usually never makes it west of 50W - just my opinion...

It's not at 15 N Frank...it's at 14.4 N Just messing with you. I agree.

Re: ATL: ERIN - Models
I may be wrong but it looks like the 12zGFS shows this combining with pouch 20 and heading for Florida at about a week so indeed this may not fish after all but it isn't too likely to redevelop as it heads there
