IEM :: About NEXRAD Composites gives a description of WMS-T as:
A special way you can interface with this data archive is via the Web Map Service that also supports time based retrieval (WMS-T). Point your WMS-T aware app at:
The nexrad-n0r-wmst layer is time aware!"
and the latest ( 5 minutes old) composite can be added to ArcMap and AGOL by creating a WMS connection to http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r-t.cgi? .

-Service Error Code:InvalidDimensionValue
