Per square mile, Montgomery County leads Maryland: 97 days with a hail report since 1955, 196.7 per 1,000 square miles of land. By raw count, Montgomery County has the most hail records (191 since 1955); large counties collect more records simply by covering more ground, so the ranking counts days with a record per unit of area (a storm filed for several forecast zones adds several records but one day).
