For the storm observed in the earlier blog the MESH algorithm is kicking out between a half inch and an inch. The reports that came back almost immediately following this storm were very similar at around 7/8 inch.  In the past for a high plains environment hail algorithms would kick out hail of about double what occurred in reality. This newer algorithm seems to negate the old “factor of”  methodology or at least will force the forecaster to re-acclimate  to a new “factor of” or a new rule of thumb.
