GFS is the only model to pick up on anything out there, and the cyclone phase diagrams on it show a hybrid structure becoming more extratropical as it approaches shore. I'm going to chalk it up to convective feedback or an overzealous model for now, unless something comes up in another model or in reality to suggest otherwise.

BTW, did you all know that the GFS is only the 6th best global model nowadays? The ECMWF is best, and models from Japan, UK, and Australia are all better as well. The GFS has been pretty active with developing lows this year...I wonder if they didn't change something around with the model this year. Anyway, there's nothing to worry about out there now.
