The boundary layer will become more unstable and thus causing upward motion (rising air) tonight within the vortex (cyclonic rotation) as the ocean releases latent heat overnight (diural pulse). This will fire convection in and around the center.

Latest visible images show convective bands north and west of the center. Apart from the dry air issue some ENE shear is holding convection from raping around the eastern side.

Hope this helped!!
