Hail in Clay County, South Dakota
Hail June 2, 2025 · Clay County, South Dakota
Where the report was made, with tornadoes recorded within 15 miles over the years.
The wider storm
Scattered strong to severe thunderstorms developed late afternoon along a slow-moving frontal boundary. Even with fairly weak deep-layer shear, strong instability resulted in large hail. Drier air and advancing cold pools later in development produced spotty damaging winds. High moisture content and slowly progressing storms also produced some locally heavy rainfall with rates briefly from 3 to 5 inches per hour.
A particularly intense and long-lived supercell developed near Vermillion and tracked southeast, generating hail up to golf ball size and a swath of damaging winds along Burbank Road up to 85 mph.
Began near Vermillion (42.7800, -96.9200).
