Let's eliminate the hard-coding of the grid vs. not (which is a thredds server issue) by actually using the catalog. So let's update to something like:

cat = TDSCatalog('https://www.ncdc.noaa.gov/thredds/catalog/namanl/201604/20160416/catalog.xml')
ncss = cat.datasets['namanl_218_20160416_1800_000.grb'].subset()

" '201604/20160416/namanl_218_20160416_1800_000.grb')\n",
"now = datetime.utcnow()\n",

This line isn't even used, and really doesn't make sense for archived data.
