(Undated) — Thunderstorms could put a damper on some Fourth of July plans across South Dakota. Meteorologists say stormy weather may pop up fast this holiday weekend, and lightning is the main concern. July is the deadliest month for lightning deaths, but the state hasn’t had one since 2015. Experts want to keep it that way, warning if you hear thunder, head inside immediately. Don’t try to wait it out or crouch down. Stay away from plumbing and anything plugged in. And wait at least 30 minutes after the last thunder before heading back out.
