Why?

The main reason is the general global synoptic setup...there are gonna be continuous smaller trofs (shortwaves to us weather goobers) that are gonna swing by Izzy over the longer term...as long as that flow pattern continues (which there is a model consensus that it will, no matter HOW long Izzy stays in the Gulf), as soon as Izzy gets far enough north, he is gonna be picked up by one of them...be it the first or the 7th or the 30th or whatever...unless the troffing over the east breaks down completely or is substancially weaker than all the data we have points to, there is gonna have to be a north AND east component at some point.
