Look at the 48 hr 00z NAM it actually has the main low north of Cuba and a second weak low south of it. Then it does a fujiwara effect sending Isaac west towards the keys then North again. Strange but a definite shift to the west. I believe this is the first run to show it on the west coast. Not that I believe that track but trying to get some insights into what the big boys are gonna do tonight.

In the beginning, the giants of weather started posting on the internet. Dericho, John and Mike C, frank pelligrini, cycloneye, hank frank, Jason Kelly, Lois Cane, and yours truly. Well me, I don't even own a computer any more and so be it. I haven't even logged into an account since like 2009. But like Superman, when you need his ass, he might be around. So here is the deal. Models have swayed from out to sea, to Miami/SC-NC, to the West Coast of Florida to the panhandle and now, possibly points farther west. I still think it is way too early to pinpoint any landfall assuming Isaac can get and keep his act together. We don't know, and we won't know for about 4 days what's really going to happen. So even though this is the model thread, there is one place you can go to see what will happen in the 6-10 day range. That is the joint typhoon warning center. Go look at the forecast graphics for Tembin and Bolaven. Its all there. 6 days out, the teleconnection is ridging in the SW Atlantic in the Northern Hemisphere. Based on Bolaven's track alone, up in behind the Korean Peninsula, it telegraphs a NW FL/AL hit. Now whether the jtwc's track verifies remains to be seen. Stay tuned. But the lack of a recurve here with a NW/WNW bend in the interim, would wake me up if I lived between Bay Co., FL and Jackson Co., MS. Just some food for thought while you are waiting on more models to come out. Love to all, especially up in Lincoln Park, I'll. ;) this post is fully disclaimed as per site rules yet it sends all the love I got to all y'all. Keep the discourse up to a level you would be proud of, and I will see you all next major threat. Peace.

Well, if that is right...the Alley way there, then we could see some swings back towards the right tonight.

NHC sees the weaker ridge too. From 11 PM disc.

A MID-TROPOSPHERIC TROUGH
OVER THE SOUTHEASTERN U.S. IS CAUSING A BREAK IN THE SUBTROPICAL
RIDGE. IN RESPONSE TO THIS...ISAAC SHOULD TURN TOWARD A MORE
NORTHWESTWARD HEADING OVER THE NEXT FEW DAYS. THE MODEL CONSENSUS
HAS SHIFTED A BIT TO THE RIGHT DURING THE FIRST HALF OF THE FORECAST
PERIOD...PRIMARILY DUE TO AN EASTWARD SHIFT OF THE LATEST GFS
TRACK. THE OFFICIAL FORECAST IS NUDGED A BIT TO THE RIGHT
OF
THE PREVIOUS ONE AND IS SOMEWHAT FASTER BASED ON THE LATEST MODEL
GUIDANCE.

Not to be off topic too much, but I think that should be a firing offense for a TV met.. just my opinion.
