[idvusers] Rapid Refresh model output

I have been using the motherlode server (
http://motherlode.ucar.edu/thredds/idv/models.xml) to get the RUC model
(20km version).  Now that the Rapid Refresh (RAP) has replaced the RUC,
this data isn't flowing anymore.  Is there a new place to access RAP data
for the IDV?  Particularly the 20km and/or 13km grids?  Thanks!
