Just listened to the weather chic on ABC. She used my favorite water vapor loop to sell this sucker going to NO. But, I see something different in the radar. There are three ridges. One in the Atlantic, one in the GOM and one over Texas/Louisiana. There is one trough, over the northern GOM. The met said the ridge in the GOM was what was steering Ivan WNW and preventing the northern turn. She said it was strong and would continue to delay that turn and it would end up going right to NO. (Well, she was more descriptive, but I forgot everything she said... which is why I like text reports). Anyway, it seems like the little ridge in the GOM is terribly weak and will soon go away. So, that should turn the storm. Also, the trough is now moving slightly east, as it has been moving slightly west last couple times I looked (like last nightish). What am I missing?
