NBM GRIB data can be a bit finicky. A good starting point could be to try parsing out a variable that you're trying to plot in GrADS, using
<span style="font-family: monospace;">wgrib2 blend.grib2 -match ":TMP:2 m above ground:" -grib blend_parsed.grib2</span>, then try making a new Control and Index File.</div>

</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
If that doesn't work, try re-writing the entire grid using:
<pre style="overflow-wrap:break-word">wgrib2 blend.grib2 -match ":TMP:2 m above ground:" -ijsmall_grib 1:2345 1:1597 blend_regridded.grib2</pre>

<div><br>
</div>
<div>Curious if anyone has had success with NOMADS NBM data and grads.

<div><br>
</div>
<div>I've followed the basic procedure, download the grib2, make the control file, gribmap it and run grads. I see all the fields but when I plot everything is undefined upon a basic variable plot.</div>
<div><br>
</div>
<div>Before I dig too deep, I just wanted to see if anyone is having success with this.</div>
<div><br>
</div>
<div>Thanks for any help on this.</div>
