[IDV #BLU-680297]: MRMS grib2 files

Scott,

We actually have a fix for this but unfortunately it is not available in the
current version of the IDV.

If interested, see here for the nitty-gritty details:

https://bugtracking.unidata.ucar.edu/browse/TDS-529

Rendering these data with an IDV that contains ncIDV 4.6 should eventually do
the trick. We don't have a firm ETA on when exactly that is going to happen,
unfortunately.

Best,

Unidata IDV Support
