The storm made for a soggy set up for the start of Rapid City's Summer Nights festival, but festival president Sandy Schwan said the show had to go on.
Groups were still setting up booths as the start of the street festival drew near.
The stage construction was delayed, so Schwan guessed the band schedule might be a little skewed.
But wet weather is nothing new for summer nights. She said it seems to rain every year on the first night, and she still expected a decent turn-out.
"If it had been a beautiful day," Schwan said, "I think we could have had 7,000 [or] 8,000 people. Last year, our biggest day was 12,000 people. So with the weather, all things considered, maybe 4,000 or 5,000 people tonight."
The summer nights festival in downtown Rapid runs Thursday nights until 8:45.
