ProbSevere MRMS fields vs. Single-source radar fields

NOAA/CIMSS ProbSevere display with kapx 0.5-degree Base Reflectivity, 1744 UTC on 22 July

Note the radar object above, enclosed in purple, from the MRMS (Multi-radar, Multi-sensor) fields, differs from the 0.5 Base Reflectivity field from the Gaylord, MI radar displayed.  This is to be expected because the MRMS is composite reflectivity from a variety of radars (in the case above, likely Gaylord, Marquette (MI) and Green Bay (WI)).  Do not expect a field from a single radar to overlap the MRMS fields.
