It does look as if some of the remains of x-Richard have been drawn into & energized an elongated N-S oriented surface trough, which has itself T'd with the progressive cold front pushing deeper into the GOM. Tropical cyclone development looks very unlikely in the GOM over the near-term, but together these features do look to be juicing things up in the there, and now into Florida. Go rain!

What may be more interesting, is that even if nothing comes of the x-Richard/trough/cold front trifecta, these features may serve to help put enough moisture into the western Atlantic that should 91L be something if and when in the Caribbean, it may now not have as much dry air to contend with.
