Shear Already Becoming a Factor
Latest infrared satellite imagery shows that the low may already be having some trouble with the shear farther west. The convection is becoming more elongated. If the NHC doesn't classify the low within the next couple hours you can forget about it.

The low has become rather disorganized this afternoon. Satellite imagery shows that westerly shear is already chewing on the leading side, resulting in a more elognated appearance and a very minute inflow pattern. As it moves further west, the shear only gets worse due to that quasi-stationary upper level trough to the north. There is still a very small chance it will organize again tonight, especially if it doesn't move any further to the north. However, given the shear right now I wouldn't count on it.
There has also been some speculation on re-intensification further west, in the Caribbean. I would discount this scenario too. Due to the strong tropical upper tropospheric trough, the shear in the Caribbean Sea isn't any better than it is directly ahead of the low.
IMO, this thing is toast. It's an extremely rare feature for this time of the year, however, so cherish this moment while you can.

It appears that Dr. Steve Lyons has reasons for saying why he thinks Tropical Depression 2 may not weaken because of the shear that exists to the west of the system.
There have been tropical systems that have hung tough through relatively high wind shear. I am not sure about Kyle last year, but "he" weakened and intensified several times over its existance.
