Bob,
This warning message is stating that the forecast file has a valid time of 20100303_030000 and the observation file has a valid time of 20100303_060000.
It looks like you sent me information about the previous day, 20100302. Regardless, it looks like the observation file times are as expected - to be valid at hour 06. But for some reason, MET thinks
that the model file is valid at hour 03. Based on the wgrib output you sent, that doesn't look right. Seems like it should be valid at hour 06 as well.
If you'd like, you could send us a sample fcst and obs file you're using. I could run it through Grid-Stat and try to figure it out. If you'd like to do that, please post them to our anonymous ftp site:
ftp ftp.rap.ucar.edu

password="your email address"
cd incoming/irap/met_help/craig_data
put "your files"
bye
I'd just need the NetCDF output of PCP-Combine and the model file you're verifying. You already sent me the Grid-Stat config file.
Thanks,
John Halley Gotway
