SIOUX FALLS, S.D. (KELO) – A heatwave is expected to settle into KELOLAND this weekend and may disrupt some outdoor events in Sioux Falls. 

The National Weather Service issued an extreme heat warning for southeast South Dakota from noon Friday to 9 p.m. Sunday. Heat index values could get up to 108 degrees. 

Storm Center PM Update: Extreme Heat Returns

Levitt at the Falls has pushed back their Friday and Saturday concerts by an hour. They will now begin at 8 p.m.

“By about 7:30 p.m., the heat index will start to break and get a little bit cooler, so we made the decision to just delay until that starts to happen,” Levitt CEO Nancy Halverson said. 

Singer Kelley Hunt and The 5 and the band Flobots are performing on Friday and Saturday night, respectively. 

Halverson said they normally don’t allow umbrellas on the Levitt lawn, but due to the heat, they’re making an exception this weekend. 

“If people want to bring a small shade umbrella … like one that you hold yourself, they can kind of sit on the edges,” she added.

Levitt staff will be handing out free water bottles to guests. The first-aid trained staff and EMS trained security guards will be at the concert to address any emergencies. 

Friday and Saturday is also the Denny Redmond Memorial Fastpitch Softball Tournament at Sherman Park. Gary Young, the event director for Sioux Empire Fastpitch, said the tournament is still scheduled as normal, but officials will play it by ear when adjusting games. 

“If something comes up where we think it’s too warm, we can do three things actually: we can cancel for the day, which we hardly ever do, we can shorten games up if we feel the need or we can cancel for hours and try to get into the evening hours where it’s cooled down,” Young said. 

He said they may add an extra 15 minutes between games to let players cool off and rest. 

Juneteenth events across the state

The Juneteenth Celebration is from 11 a.m. to 5 p.m. at Fawick Park. The event will have free water, additional shaded areas and sprinklers for people to cool down under. 

“We want to have a safe event, we want to have a fun event and we can’t do that if people are having heatstroke and fainting,” said Ashley Knoff, a Juneteenth committee member. “Wearing sunscreen, wearing hats, wearing layers, no matter what kind of skin tone you have, they’re all susceptible to heat.”

For anyone planning on spending a lot of time outside this weekend, Halverson is encouraging people to drink water and know their limits. 

“Just really, people be mindful of how they feel and to get into shade or make sure to drink lots of water if they start to feel dizzy or uncomfortable in any way,” she suggested.
