| June 2025 | Tornado (EF3) | Clear Lake | 2 hurt | A tornado developed east of Clear Lake, South Dakota, on the evening of June 28, 2025. Around 8:10 p.m., the tornado was still in a disorganized stage but was strong enough to intermittently touch down, rip a roof and door off of a barn and flip irrigation pivots on the north side of Highway 22 about two and a half miles east of Clear Lake. By approximately 8:14 p.m., the tornado crossed to the south side of Highway 22 and began to intensify. From there, it tracked slowly eastward, frequently changing appearance. Numerous reports, photos, and videos captured the tornado shapeshifting, including a distinct wobble or dancing motion. During this time, the tornado passed over a gravel pit, where large trees were snapped and windows were broken out of heavy machinery. Continuing east, the tornado reached 483rd Avenue, where it caused additional tree damage. Around 8:26 to 8:27 p.m., it crossed back to the north side of Highway 22, briefly stalled, and brought down a power pole. The tornado then picked up speed and continued east toward a farmstead on 484th Avenue, arriving around 8:31 p.m. The core of the tornado passed just north of the main house, but the property still sustained significant damage. A portion of the house roof panels were ripped off and windows were broken out. A machine shed was completely destroyed, along with a garage and another outbuilding. The shelterbelt on the north side of the property was heavily damaged, with tree trunks snapped, trees uprooted, and large branches broken. Around 8:32 p.m., the tornado continued east, passing north of another farmstead where a single shed was destroyed. Then, at approximately 8:34 p.m., the tornado directly struck a farmstead. Evidence of ground scouring was visible in the field before the tornado reached the property. As it approached, it tore through a wide shelterbelt, snapping and uprooting trees and completely blocking the driveway with debris. The house, which included the original structure that was over a century old combined with a newer addition, was completely wiped from its foundation. The debris was thrown west. The residents sheltered in the basement, where hay bales were lofted into the air and landed on top of them. Despite the extreme damage, only two non-life-threatening injuries were reported. A garage and machine shed directly east of the house were also completely swept off their slabs. An SUV and a half-ton Chevy Silverado pickup were inside the garage. Another SUV was parked outside. The two SUVs were lofted and ended up wedged in trees approximately 50 to 60 yards northeast of where the garage once stood. Many of those trees exhibited debarking. The half-ton Chevy Silverado pickup was hurled nearly 300 yards northeast. The truck's rear axle was torn completely off during flight, with no evidence of the vehicle rolling or tumbling until it hit the ground. A horse trailer and other farm equipment in and next to the machine shed were also thrown into the shelterbelt. On the south side of the property, two empty metal grain bins were wiped clean from their foundations. A concrete foundation barn was dismantled, a pole barn collapsed, and an empty concrete silo was completely swept from its slab. As the track continued northeast, fence posts were sheared off at ground level, and large pieces of debris were driven into the crop ground with extreme force. A trail of debris was scattered into the adjacent fields. The tornado track turned more to the north-northeast as it crossed 181st Street. More tree damage was observed, with trunks snapped and large branches down. Debris was caught in fence lines, and hay was seen hanging from power lines in the area. The tornado crossed 180th street and somewhere around 8:45 p.m. it began to rope out, swirling over an open field and tracking back to the southwest. It finally lifted around 8:49 p.m., concluding a nearly 40-minute track that stretched roughly 9.71 miles. The tornado was rated as a high-end EF3 with wind speeds estimated between 155 to 165 mph. |

The track continued a quarter mile to the north, where a second farm had uprooted trees, complete destruction of a machine shed and a collapsed barn. The main residence also had loss of shingles and the loss of a small portion of roof panels. The track continued northeast. The next residence to sustain damage was near 772nd Ave and 181st St. The tornado entered the farm from the west where it uprooted several trees and broke branches off the tops of others, a third of a roughly 300 foot long milk barn was leveled, one stave silo completely collapsed and a second was razed about half way to the base.

An outbuilding south of the property also collapsed. Just shy of a mile to the northeast along 473rd Ave a machine shed buckled on the southwest side.
