Last month (on March 19 or so), changes in the contents of the NAM awip3d 
analysis and forecast (in GRIB2 format) on the CONDUIT feed exposed a bug in 
the WRF Preprocessing System’s (WPS’s) ungrib software, which has been fixed 
and made available. However, the header pattern in that product that I used to 
trigger my WRF runs seems no longer to work.

I haven’t been able to find documentation about the product patterns for the 
NAM in that CONDUIT feed that extend to the level of detail that I might need. 
Cann someone direct me to that detailed documentation, or comment on changes to 
the header patterns that might have accompanied the changes in the content of 
the NAM analysis and forecast last month?

P.S.

The header pattern I was using to trigger my WRF runs looks like this:

CONDUIT ^data/nccf/com/nam/prod/nam.20(......)/nam.t(..)z.awip3d(60).tm00.grib2 
!grib2/ncep/NAM_84/#000/20(........)..F060/(VREL)/(300 hPa PRES)!

(This is the 300 mb v-component wind in the 60-hour forecast.)
