Don't think it'll make a sharp right turn but looking at the latest water vapor there is a vigorous trough now punching into west TX. There have been a series of troughs swinging thru the last day or so, but this latest one looks more potent. The overall cloud shield of KAT is starting to elongate N-S which means that she is starting to come under the influence of the trough. This may be a good thing in that perhaps KAT will start encountering increasing shear as she moves north of 28N. At this point, its really academic where the actual landfall will be with such a massive storm. Latest 12Z GFDL brings her in right along NHC's projected path about the LA/MISS border. The GFDL does weaken her slightly going from 147 kts to 127 kts - really immaterial when your talkin that high.
