[THREDDS #ULI-448464]: Question about Total Precipitation field name (GFS CONUS 80km)



thanks for the heads up. I was able to grab the files to replicate it.
I suspect that the "wait 5 minutes after the file has stopped being updated" 
rule is not being followed.
Ill let you know what i find out.
