Why are the cloud tops of Dennis over the FL Pen. being blown off to the NNE?

That's what I asked in a few other threads. Nobody seems to acknowledge this. Everything is blowing to the NE in the N GOM.

Someone answer meeeee Wahhhhh :

Chris, very interesting. The first thing I noticed was this when I pulled up the graphics. As you might recall I don't know diddley, meaning what a ridge versus a trough are ect.....But, in this graphic, there is like a brown area that seems to be pushing the clouds in that north east direction....what is that brown patch called??? or is there a name for it? Or is it just a type of cloud.....I know, I sound like a dumb blonde

That's the weak tough.

The brown indicates dry air.

MBismyPlayground that area you are talking about could be the northwestern part of a high pressure dome tomorrow.
Problem is the arrows are still not pointing in the right direction over the bay of Campeche yet, otherwise this looks like a classic case of a ridge building over a strong tropical system.

What does that mean? What would happen if the ridge built over it, pull it west?

The NAM model built a ridge over the system and lifted out the trough that is now over the Texas coast.
Since the trough flow from the southwest was diminished Dennis made landfall further west over NOLA.
The NHC said they thought the trough would hold back at 5PM.
