Have you modified line ~382 in WRFUserARW.ncl yet?  dz can be decreased
from the default value of 0.01:

...else
        z_max = max(z)
        z_min = 0.
; Changed to:
dz = 0.002 * z_max
        ; From:
        ;dz = 0.01 * z_max
        nlevels = tointeger( z_max/dz )
        z_var2d = new( (/nlevels/), typeof(z))
        z_var2d(0) = z_min
     end if
