Holly,

OK, I see the problem.  The projection information is not correct in the forecast NetCDF file: fcst18z_06L_TMAX.nc

                :Projection = "Lambert Conformal" ;
                :p1_deg = "39.000000 degrees_north" ;
                :p2_deg = "39.000000 degrees_north" ;
                :p0_deg = "19.753263 degrees_north" ;
                :l0_deg = "168.092865 degrees_east" ;
                :lcen_deg = "-98.000000 degrees_east" ;
                :d_km = "12.000000 km" ;
                :r_km = "6371.200195 km" ;
                :ny = "299 grid_points" ;
                :nx = "447 grid_points" ;

I ran this file through the MODE tool, and I just compared it to itself:
mode fcst18z_06L_TMAX.nc fcst18z_06L_TMAX.nc WrfModeConfig

And then I looked at the PostScript file that was generated.  The data sure looks like it's supposed to be over the CONUS, but the MODE PostScript file shows it plotted somewhere else.  That's why
you're not getting any matched pairs - Point-Stat thinks that your domain isn't over CONUS.  Take a look at the attached PNG file to see where MODE plots it.

I thought maybe that l0_deg = "168.092865 degrees_east" was supposed to be "-168.092865 degrees_east" but that didn't do the trick.

Do you have some numbers that define what the projection is supposed to be?
