[gradsusr] %f3 gribmap template starting at different fct time steps

[Wesley Ebisuzaki - NOAA Federal]

Hi,

  Download the

    gfs.t00z.pgrbf000.grib2

G2ctl assumes that templated forecast files start with fhour = 0.  Since a
fhr = 0 precip
may not exist, you have two choices.

   (1) edit the ctl file by

           tdef 9 linear 03Z27Apr2015 3hr to tdef 10 linear 00Z27Apr2015 3hr
                             (date)        (dt)
