Can anyone speculate about why Don fell apart so spectacularly? Was it the dry air that had been choking it from the north? Some other factor?
We're all very disappointed here in South Texas. This was a huge let-down. We've had traces of rain this morning, but of course, nothing like what was (eagerly) anticipated.
As far as I can tell it was a rush of dry air from the northeast Gulf, combined with the shear and dry air over texas. The rush was enough to completely decouple the system (it was tilted already the entire time it was in the central and west gulf). That last bit was enough to break it apart, then the dry air just did it in.
