there seems to be more factors involved. we have some storms east florida coast, does not seem to be flowing with storm. then if you look south around mexico(bay of campeche) you have to wrap arounds. one going east one going west. then north, it wants to go north but something is holding it back. some from corpus to miami WATCH.

I saw the same thing. He is not ruling anything out at this point. When a storm gets in the Gulf, it is going to go somewhere and we all have to be on guard.

Now that it seems that Isaac has locked onto the NOLA, MS, AL coast...at least we can say that the Hurricane Hunters are flying out of Ellington Field. :D

Not derail the topic at hand, but as savvy as I am concerning the Tropics, I felt fairly confident that the NHC as well as the 'local meteorologist' had a good handle on just what Katrina was going to do on August 25th back in 2005 by crossing the Peninsula. Now picture my home being on a canal with a boat and plenty of outdoor furniture and plants. I wasn't even in a Watch in the Lower Keys when I woke on Thursday, August 25th. Much to my surprise as well as forecasters, Katrina had a mind of its own and decided to turn SW by 11PM that same day and ended up in Florida Bay N of my front doorstep by about 40 miles. That is the very reason I always state until a storm is inland and dead, we should keep an eye on things...;)

I'm with Doc on this. Until he is onshore and is actually moving out to the North.... Blah Blah

Edit to say... Come on, folks. I mean really. Doc does not mess around. If he thought this to be over for Texas, he would have said so.
He thinks like my old Buddy, Harold Taft. Models are good for what they are supposed to be good for. They are NOT the end all in forecasting. So many forecasters today live by them, but have no sense of reason or that natural gut feeling that real weather forecasters get. Anybody can go to school to be a weather reporter. Then we have men like Doc. Listen to him.

Does anyone have a link to long term satellite/water vapor runs. All the links I have are for a short time. I'd like to see 8-12 hour daytime loops...

Ok so here's my dumb question of the evening. I'm looking at the satellite and the size of the storm. If the eye comes in anywhere to the west of NOLA or angles in to the coast, doesn't it look like the outer squals would be on the eastern side of our area? I mean, I can't help but hope that some of the drought areas east of us get some relief from this, but it's a pretty wide storm. Like I said, just a curious questions.

Go to the NWS home page. Click on Satellite page, and click on the 24 hour loop of the water vapor. ;)

I've been all over that site, even on the Satellite page and still can not find the 24 hour loop... I must be blind!

Edit: I found it!... Thanks!

While it would be possible for a squall or two to reach into SE TX, we will be fairly well removed from the circulation. Will need to see how and where any dry air entrainment is when the system is nearest its approach to our area. Right now the dry air is east through north of the center with all the convection south and west
