OK, so the issue with the 40-km grid was resolved by simply increasing the 
number of grids in the GEMPAK file.

The issue with the 12-km grid persists though, and appears to be related to the 
fact that the hourly NAM files are not coming through on CONDUIT past 36 hours, 
yet GEMPAK is looking for them when it tries to plot the longer-duration 
precipitation accumulations.  (Example belowâit canât find the file at 44 
hours, because it doesnât exist.)  Is there a way to either have the hourly 
files (beyond 36 hrs) pushed out, or to let GEMPAK know to only look for the 
3-hourly files?
