Two batches of severe thunderstorms, occurring within 6 hours of each other, dumped hailstones up to 4.5 in (11 cm) in diameter across Sedgwick, including the city of Wichita, and surrounding counties in south-central Kansas. Over 10,000 homes were damaged. The hail left wheat fields in a near total loss. Estimated property damage totaled $500 million with crop damage at $100 million. The thunderstorm episode ranks as one of the worst ever to hit Kansas.[7]

Orange-sized hailstones caused almost $300 million worth of damage in Calgary and Winnipeg, as well as serious flooding. Notably, one-third of cars damaged by the storm were irreparable.[11]
The last known hail fatality in the United States occurred. The victim was Juan Oseguera, a nineteen-year-old man who died from head injuries after being hit by a softball sized hailstone in Lake Worth.[12]
$572 million. Golfball-, baseball-, and softball-sized hail damaged roofs, cars, patio furniture, skylights, and windows in the area's worst and most widespread hailstorm in 30 years (McHenry, Lake, northern Kane, northern Cook County). Around 100,000 homes lost power. Hail was 3 in (76 mm) deep in many areas. There were 100 canceled flights, and train service was disrupted.[13]

Over 90 people attending a Louis Tomlinson concert at Red Rocks Amphitheater were treated on-site as a result of hail related injuries. Seven people were hospitalized.[38]
An unusually strong storm blanketed a large portion of the northeast Denver metro area in the late evening. Golf ball-sized stones damaged homes and vehicles, in an event comparable to the May 2017 hail storm. Due to the late hour the storm hit, much of the hail would not melt until the following day. [39]
One of Britain's worst ever hailstorms, possibly a supercell, caused massive destruction as hailstones reached up to 1.5 m (4.9 ft) deep in places. The storm is also believed to have spawned several tornadoes, and the exact size of the hail that fell within it is unknown. The overall damage was so great that an entire new insurance company, The General Hail Insurance Company, was formed to help cope with future hailstorms. This company would later be known as the Norwich Union.[42]
The hailstorm lasted for 5 minutes, causing heavy damage and killing many sparrows. Streets were covered in some places with 90 cm (3.0 ft) of icy slush. The largest pieces were over 2 cm (0.79 in) in diameter. [43]
Mineral dust blowing in from the Sahara met cold, moist air over the British Isles, forming unusually large hailstones (at least 7.5 centimetres (3.0 in) across, possibly 10 centimetres (3.9 in)) around the dust. In the thunderstorms that ensued, hail piled up to 45 centimetres (18 in) deep and many towns flooded.[44]
Tennis ball sized hail fell on Munich and surrounding areas on this date.[45] It was the greatest loss event in the history of the German insurance industry: 200,000 cars were damaged and the storm cost an estimated 3 billion Deutschmark.[46] For years afterwards people jokingly referred to those cars whose bodywork was not repaired as 'Munich Design'.

The 1490 Qingyang event may have been due to a large comet breaking up in the atmosphere, or a hail storm. Sources generally considered reliable say more than 10,000 killed, but the official History of Ming does not give a number of casualties.[57][58][59]
One of the deadliest hailstorms of all time killed at least 230 people, and over 1600 sheep and goats, in Uttar Pradesh. The hailstones were reportedly as big as oranges, and in some areas piled up to 2 ft (0.61 m) high. No warning system existed in 1888 and therefore the death toll of this event was exceptionally high.[60]
At least 92 people were killed in Gopalganj by some of the heaviest hailstones ever recorded, which were the size of grapefruits and weighed around 1.02 kg (2.25 lb) each.[61]
According to Japan Meteorological Agency official figures, a freak storm occurred between 13:00 and 18:00 local time. This was due to the 15–20 degrees (C) temperature difference between altitudes above 10,000 meters and sea level. Tennis ball, table tennis ball, golf ball size hail and extremely heavy rain fell widespread in the Kanto area, damaging agriculture, personal vehicles, houses, and buildings. 93 people were injured in Gunma Prefecture, according to Japan Fire and Management Disaster Agency.[citation needed]
1947 Sydney hailstorm: Early in the afternoon, a storm cell that later formed into a supercell thunderstorm swept in from the south west dropping hailstones larger than 8 cm in diameter over eastern-south west Sydney, inner west, CBD and the eastern suburbs. hundreds of people were caught on Sydney's beaches as the Hailstorm reached the coast line with many knocked unconscious. This event adjusted for inflation caused A$45 million in damages.[65]
Late in the afternoon, a supercell thunderstorm swept in from the west dropping hailstones as large as 6 cm (2.4 in) over parts of the city. A wind gust of over 180 km/h (110 mph) was recorded at Brisbane airport and 57 mm (2.2 in) of rain recorded in 15 minutes at the same location. The 30 minutes of destruction caused A$300 million (A$1.7 billion in 2007 adjusted dollars) damage to vehicles and buildings. This rates as the 5th most costly insured event in Australia since 1968.[66][67][68]
1999 Sydney hailstorm: 20,000 properties and 40,000 vehicles were damaged during the storm with more than 25 aircraft damaged at Sydney Airport. One person was killed while fishing after getting struck by lightning and several other people were injured.

The 2020 Canberra hailstorm caused severe damage to cars, buildings, trees and local wildlife.
It struck just after midday and passed in a South Westerly direction across the city. Areas of most impact were the inner city suburbs. Many cars were written off by the damage. It also affected the local wildlife taking shelter in the trees with leaves and branches broken by the ferocity of the hail.[75]
The 2020 Brisbane Hailstorms caused major havoc in the southern and western suburbs of the city, with some isolated areas to the north. Damage in excess of AU$50M was recorded on 1 November alone, possibly the day with the most severe weather. Heavily affected suburbs included Coomera, Victoria Point, Ipswich, Amberley, Brisbane's CBD, Redcliffe, and Springfield, which recorded 14 cm hailstones. The event signified the beginning of a forecast La Niña weather phenomenon, in the wake of its destruction.
