Carmel hail storm history
Hamilton County·NOAA NCEI Storm Events Database·~75-day publication lag
Carmel, located in Hamilton County, sits within a central Indiana corridor where spring storm systems from the Great Plains and squall lines from the Midwest converge to produce hail. This geographic positioning places the city at the intersection of several common severe weather tracks that originate from both the Ohio Valley and the western plains.

Hail in Carmel occurs most frequently during April, May, and June, when atmospheric conditions favor organized storm development across the region. March and July represent secondary risk months. These spring and early summer storms typically form along boundaries where warm, moist air collides with colder upper-level air masses, creating the instability needed for hail production.
