Issuing SVR on Eddy storm now.  Strong mid-altitude rotationat 14 kft.  Over 60 dBZ @ -20degC.  16 kft H50_above_H253.  MESH > 1.5″  MESH history for continuity.  MR helped refine the warning.  Helped to contruct polygon.  MESH track revealed the right turn, and polygon was adjusted for that.  Spotter report alone might have messed up track.
