Which counties in Wyoming have the most hail reports?

Per square mile, Laramie County leads Wyoming: 403 days with a hail report since 1955, 150.0 per 1,000 square miles of land. By raw count, Laramie County has the most hail records (1,113 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).

  2. Goshen County 107.8 (458)
