Hi Mike, 

Chiz ~was our CONDUIT expert, but I will take a crack at what i see ~may be an 
issue.

Please see:

http://www.unidata.ucar.edu/data/conduit/ldm_idd/gfs_files.html

Note that for some grids the forecast hour goes from a 3 digit filed to a 2 
digit field. I also noticed that the files you get:

F003, F006, F009

would match the same as 12 hour forecast times:

F036||F060|F096...if they were using a 2 digit field F06 vs F006, and F06 would 
match F06 and F060.

One way to get around this would be a more strict reg exp to not allow F060 to 
match F06.

Again, this is a stab, but I think it may be the crux of the issue :)

Hope this helps,

Jeff
