This is a known problem with the GFS grids (see:

http://my.unidata.ucar.edu/content/software/idv/docs/userguide/Bugs.html#faq1_cat3_11

since they are on a latitude/longitude native grid.  The problem is
that we don't take into account the variation of longitude in the
y direction.  I hope to be able to fix that by the next release.
