[GEMPAK #TAG-149000]: CFS v2 Grib Files



Hi Allan,

this is likely a grib table issue, which may be solved with the newest GEMPAK 
tables from NCEP.  I am working on updating the tables for the UPC GEMPAK 
release, but it is not done just yet.  I will write back when it is complete 
and I'll be sure to test the CFS files.  I am on PTO after today so will not 
have a lot of time to devote to work, but may steal away for a morning session 
or two so I can keep up on tickets like this one.

Michael
