Seagayle,

We recommend using the copygb utility for regridding GRIB files.  We haven't included any interpolation options within MET itself, but instead, we require that the input fcst/obs fields reside on the
same domain.

The copygb utility is distributed as part of the WRF Post-Processor.  So if you have WPP installed, you'll already have copygb.  If not, you can also access it from the NWS Climate Prediction Center Page:
http://www.cpc.noaa.gov/products/wesley/copygb.html

If you have any trouble getting copygb to do what you'd like it to do, I'd be happy to help.
