John, I have another error which I can get past and it is listed below:

Even though it is degribbing a 3 hour accumulation valid at 1309120618, it is not finding it in model_pcp file. I have included the model_pcp file at the FTP website. A grib listing of the file is:
1:0:d=13091206:APCP:kpds5=61:kpds6=1:kpds7=0:TR=4:P1=12:P2=15:TimeU=1:sfc:12-15hr acc:NAve=0

The precip record for 20130912 valid at 18Z, 9-12hr forecast, should not be included in the 12hr accumulation of precip from lead time of 12hr to 24hours. I did notice that if I include the 9-12hr data in model_pcp file, the error will change to "Cannot find a file with a valid time of 20130912_150000 etc.". So not sure what going on here.
Let me know if you need anything else.
Thanks

Bob,
I think you're close on this one, but just a little bit off.
I ran the command using the data you sent and reproduced the same
error message you're seeing. Listed below is a subset of the wgrib
output with some comments at the end of each line...
1:d=13091206:12-15hr acc ---> 15-hour forecast valid at 2013091221
2:d=13091206:15-18hr acc ---> 18-hour forecast valid at 2013091300
3:d=13091206:18-21hr acc ---> 21-hour forecast valid at 2013091303
4:d=13091206:21-24hr acc ---> 24-hour forecast valid at 2013091306
However, looking at the pcp_combine command you ran, I see the
following:
- 20130912_060000: You're only using forecasts initialized at this
time.
- 3: You're using an input accumulation interval of 3-hours.
- 20130912_180000: You want the resulting accumulation to be valid at
this time.
- 12: You want an output accumulation of 12-hours.
Based on this command, pcp_combine is looking for 4 GRIB records with
accumulation intervals of 3-hours valid at 20130912_090000,
20130912_120000, 20130912_150000, and 20130912_180000.
Since your forecast is initialized at 20130912_060000, you really want
to sum up the 3, 6, 9, and 12 hour forecasts to produce a 12-hour
accumulation between 20130912_060000 and 20130912_180000.
Clear as mud?
Just let me know if you have more questions.
Thanks,
John
