Reports of hail as big as golf balls from the National Weather Service in Rapid City came with widespread thunderstorms Saturday.
Golf ball-size hail was reported southeast of Deadwood on Saturday afternoon, according to meteorologist Kyle Carstens, with the NWS. He said there was a possibility of baseball-size hail if storms were to grow stronger east of the Black Hills.
Downtown Rapid City received pea-size hail early Saturday evening forcing Main Street Square live music events to take a break until the storm passed.
A tornado warning was issued for the area just south of Wall as the storm moved eastward. No tornadoes were reported as of Saturday evening.
Carstons said the storm system in Nebraska moved into southwestern South Dakota and the Rapid City area Saturday evening. The system had favorable conditions for producing tornadoes.
For today, the forecast calls for rain showers and thunderstorms to be likely with a 70 percent chance of precipitation. Temperatures will reach the upper 60s. Northwest winds are expected to be 10 to 20 mph.
