[Met_help] verifying 2m temperaures with PointStat

[Joe Olson]

I'm trying to verify 2m temps output from WRF-ARW v3.0 and using  
METv1.1 (PointStat).

First, I have performed the following to prepare the prepbufr:

1) cwordsh block prepbufr_file prepbufr_file.blk
2) Converted Prepbufr to netcdf:
         /METdir/bin/pb2nc prepbufr_file.blk prepbufr.ncdf / 
METconfigdir/PB2NCConfig

So far, this seems to work fine, since I have successfully used this  
file to verify upper-level temperatures...

Then, convert wrfouts (netcdf) to an A-grid (grib)
3) run_wrfpost
     This outputs my wrfprs_d01.XX file.
      In the wrf_cntrl.parm configuration file, I made sure to specify  
various forms of temperatures:

  (SHELTER TEMPERATURE ) SCAL=( 5.0)
  L=(10000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000  
00000 00000 00000)
  (TEMP ON PRESS SFCS  ) SCAL=( 4.0)
  L=(11111 11111 11111 11111 11111 11111 11111 11111 11111 10000 00000  
00000 00000 00000)
etc...

Then, when running PointStat with the output from (2) and (3) and  
using the following edits to the config file:

vx_grib_code[] = [ "TMP/Z2"];
thresholds[] = [ "gt0"];
message_type[] = [ "ADPSFC", "SFCSHP" ];

I get the requested output, but looking at the mpr file, the model  
forecast is way too cold (229-233 K) while the observations seem  
correct (270-278 K)

etc....

Has anyone seen a problem like this? Are there any other steps I need  
to consider?
