Meteorological historyEdit

On June 18, afternoon heat had persisted, resulting in the creation of severe thunderstorms. However, the thunderstorms had not fully matured until later that evening, as warm air kept the thunderstorms from developing. Thereafter, severe thunderstorms originated from a boundary, after the warm air weakened, which led to repeated rounds of thunderstorms and flooding, which was situated by a complex of thunderstorms over Iowa.[2]

ImpactEdit

HailEdit

FloodingEdit

A body was found in Bloomington, Indiana after he drove through floodwaters and drowned.[3] One street in Bloomington was several feet underwater, and as much as 7 inches of rain was reported in Ellettsville, Indiana.[4][5][6]

Seven tornadoes touched down in Kentucky, Indiana, Ohio, and Illinois as a result of a severe weather outbreak that affected the Ohio Valley region. Two EF2 tornadoes caused severe damage to trees, outbuildings, power poles, and homes near Portland, Indiana and Fort Recovery, Ohio respectively.[7][8] A high-end EF1 tornado struck the town of Milan, Indiana, downing numerous trees, destroying a garage, and tearing shingles, siding, and gutters from homes. Another EF1 tornado near Moores Hill, Indiana damaged two homes and downed trees. An EF1 tornado also caused roof and tree damage near Germantown, Ohio, while another EF1 tornado damaged farm buildings, crops, and trees near the town of DeLong, Illinois. Numerous reports of straight-line winds, large hail, and flooding were received as well.[9][10] More than 40,000 people lost power during the storm.[11] Numerous flash flood watches, warnings, and tornado warnings were issued in parts of Illinois, Indiana, and Ohio.[12] Combined, the tornadoes inflicted $1.56 million in damages.

Several farm buildings were completely destroyed with debris strewn through fields, and multiple homes at farmsteads were severely damaged. A 100 ft (30 m) telecommunications tower was toppled, and trees were snapped or uprooted along the path. Several cattle were killed.[13]
