1960: A late evening thunderstorm cut a path of destruction, principally from high winds from Beadle County, northeast to Roberts and Grant Counties. Twelve head of cattle electrocuted for a downed high tensions wire occurred at Wolsey. Winds with gusts of 65 to 75 mph were observed at Huron and Watertown. A grain elevator tipped over and a windmill was destroyed near Willow Lake. A Steel corn crib was blown over at Hayti and damaged occurred to other farm buildings and implements.

1889: At 4:07 p.m. the inhabitants of Johnstown, PA heard a low rumble that grew to a "roar like thunder." The South Fork Dam had broken, sending 20 million tons of water crashing down the narrow valley. Boiling with huge chunks of debris, the wall of floodwater grew at times to 60 feet high, tearing downhill at 40 mph, leveling everything in its path. 2200 were killed that day.

1911: A violent derby day thunderstorm killed four horses on Epsom Downs in Southeastern England. Local flooding, landslides, lightning, and wind gusts inflicted damage across lowland England. Seventeen people were killed in the London area.

1930: New Mexico's deadliest tornado, an F2, killed two men in Wagon Mound when it destroyed the auto repair garage they were in.

1935: The U.S.'s record 2-hour rainfall amount was set at D'Hanis, TX, with exactly 15 inches. The U.S.'s record 2.75 hour record rain was also set with 22 inches.

1947: A tornado swept clean the north side of Leedey, OK. Not only were homes obliterated and blown away, but the top few inches of people's lawns were swept away as well. However, the tornado took a full 5 minutes to slowly chew through the small town, so F5 winds may not have been necessary to create damage this complete.

1985: The eastern Great Lakes region's worst tornado outbreak. One of the tornadoes was an F5 that crossed from Ohio into Pennsylvania, killing 18 people along its 47 mile long path.
