We used MRMS data during storm interrogation and decided to warn for a storm over far northeast New York and far northwest Vermont.  As early as 1812z the MESH was indicating hail just over 1 inch while the height of the 50 dbz echo above -20c was over 5000 feet.  Warning decision was not made until after 1820z after looking at KCXX radar data.  1 inch hail reports were received from about that time.  Attached is a 4 panel showing the Max Expected Size of Hail (MESH), heights of 50 dbz echo above -20C, and reflectivities at the -10C and -20C levels.
