The storm that moved through Central Illinois saw hail, high winds, and lightning. But a lightning strike at the annual Summer Camp at Three Sisters Park injured two people. Authorities haven't released their identities or conditions, but did confirm both individuals were taken to an on-site medical department for evaluation before then being transported to a local hospital for further evaluation. Public safety officials coordinated with Summer Camp management to temporarily shut down all the music stages and told patrons to take shelter till the storm passed. Afterward, the event resumed.
