North Platte Hail – 2238 UTC

Got a report of golf ball sized hail 8 South of North Platte at 2238Z.  At this time, ProbSevere was low – about 40% and did not encompass LBF at all (see image).  MESH at this time was also low – 0.56.”  The hail core was fairly small – and maybe the report is suspect??  It was from a trained spotter.  Possible example of ProbSevere being underforecast.
