    Can WRF output data be used for Input data on smaller domain

    I have a 4km 120hr WRF run that is created in 5hrs. But when I nest in a 1km grid it increases the time dramatically to finish the run. So my question is can I use the output from the 4km 120hr run as initial data for a new wrf run at 1km? I don't see a vtable in ungrib for WRF on ARGWRF. So...
