Most of the tropical cyclones at higes latitudes have some baroclinic influence, for example cut-off upper level low or trough which stretching southward from the westerlies often cause upper level divergence under a tropical cylcone.
In this case the upper level low that formerly located NW of the cyclone helped the convective systems in the past days and maybe also contributed to the formation of the weak surface low yesterday, but it never had fronts and the circulation became concentrated while sustained depp convection occured in the night hours, and in addition, upper level outflow also developed over the cyclone. So it is more like tropical than extratropical or subtropical.
