Aberdeen hail storm history
Brown County·NOAA NCEI Storm Events Database·~75-day publication lag
Aberdeen is located in Brown County in eastern South Dakota, a region where hail develops frequently due to the collision of Gulf moisture, elevated terrain to the west, and the low-level jet stream. This geographic setup makes the area a consistent target for hail storms during the peak season, with recorded events ranging from common pea-sized hail to severe softball-sized impacts.

Hail season in Aberdeen peaks during June and July, with secondary activity extending into May and August. Storms during these months are driven by the interaction of warm, moist air from the Gulf and cooler upper-level air masses—a pattern that produces the most intense hail events at this latitude later in the summer compared to regions farther south.
