The January 2016 United States blizzard produced up to 3 ft (91 cm) of snow in parts of the Mid-Atlantic and Northeastern United States during January 22–24, 2016. A weather system, evolving from a shortwave trough that formed in the Pacific Northwest on January 19, consolidated into a defined low-pressure area on January 21 over Texas. Meteorologists indicated that a resultant storm could produce more than 2 ft (61 cm) of snow across a wide swath of the Mid-Atlantic region and could "paralyze the eastern third of the nation", and regarded it as a "potentially historic blizzard". Winter weather expert Paul Kocin described the blizzard as "kind of a top-10 snowstorm".
On January 20–22, the governors of eleven states and the mayor of Washington, D.C., declared a state of emergency in anticipation of significant snowfall and blizzard conditions. Approximately 103 million people were affected by the storm, with 33 million people placed under blizzard warnings. More than 13,000 flights were cancelled in relation to the storm, with effects rippling internationally. Thousands of National Guardsmen were placed on standby, and states deployed millions of gallons of brine and thousands of tons of road salt to lessen the storm's effect on roadways. A travel ban was instituted for New York City and Newark, New Jersey, for January 23–24. The storm was given various unofficial names, including Winter Storm Jonas, Blizzard of 2016, and Snowzilla.

This page documents the tornadoes and tornado outbreaks of 1999, primarily (but not entirely) in the United States. Most tornadoes form in the U.S., although some events may take place internationally, particularly in parts of neighboring southern Canada during the Northern Hemisphere's summer season, as well as Europe. One particular event, the Bridge Creek-Moore, Oklahoma F5 tornado, produced the highest wind speed ever recorded on Earth, which was 301 ± 20 mph (484 ± 32 km/h).

2024 tornado activity
A multi-day period of significant tornado activity along with significant derechos occurred across the Midwestern United States and the Mississippi Valley as well as an additional tornado in the Canadian province of Quebec. From May 19–27, 2024, two derechos occurred and tornadoes were reported across large portions of the Central United States, with multiple Particularly Dangerous Situation (PDS) watches issued across the sequence. On May 19, strong tornadoes occurred with isolated supercells in Colorado and Oklahoma while a derecho produced widespread wind damage and weak tornadoes across Kansas into the early morning hours of May 20. Limited tornadic activity took place on May 20, but another outbreak along with widespread damage struck mainly Iowa and Wisconsin on May 21. Five fatalities were confirmed with a large, violent, long-tracked EF4 tornado that went through Greenfield, Iowa. Scattered to widespread severe weather and tornadoes occurred over the next two days, including an EF2 tornado that injured 30 people on the west side of Temple, Texas. Another derecho formed in southwestern Nebraska late on May 23 and moved eastward, producing widespread wind damage and weak tornadoes through Nebraska and Iowa and northwestern Illinois before withering away in the northern part of the state during the morning hours of May 24.
A nocturnal outbreak occurred during the overnight hours of May 25 into May 26. An isolated supercell in northern Texas produced multiple tornadoes, including a low-end EF3 tornado that passed near Valley View, Texas, killing seven people. Another longer-lived supercell moved through northeastern Oklahoma and across northern Arkansas, producing several tornadoes along with straight-line winds of 100 mph (160 km/h). Two fatalities were confirmed from an EF3 tornado that struck Claremore, Oklahoma along with areas near Pryor. Later, it produced a very large EF3 tornado near Decatur, Arkansas, which became the largest tornado ever recorded in Arkansas. Another EF3 tornado killed four people near Olvey and Pyatt while an additional tornadic death occurred with yet another EF3 tornado that passed near Yellville and through Briarcliff. Another supercell in southern Missouri produced a low-end EF3 tornado that passed near Morehouse and through Sikeston, killing one. May 26 would be the most active day of severe weather; several rounds of squall lines and tornadic supercells moved through the Mid-Mississippi and the Ohio Valleys, producing widespread wind damage, large hail, and tornadoes. This included a very destructive, intense high-end EF3 tornado that prompted the issuance of four tornado emergencies across areas that had been previously impacted by the 2021 Western Kentucky tornado. One person was killed by this tornado. Severe weather activity became more isolated and scattered on May 27, marking the end of the outbreak sequence.
In all, 222 tornadoes occurred during the outbreak sequence; 21 people were killed by tornadoes while 10 other people died due to non-tornadic events as well. Over 240 people were injured. (Full article...)Tornado anniversaries
June 25
- 1950 – An F4 tornado moved through Rhinelander, Wisconsin and destroyed vacation homes near Crescent Lake, killing two people in an overturned boat and injuring 50 others along its path.
June 26
- 1994 – An F3 tornado moved through St. Joseph and Iron City, Tennessee, damaging more than 100 buildings, including 75% of Iron City. Nineteen people were injured.
June 27
- 1951 – One of the briefest violent tornadoes on record, an F4 tornado touched down in WaKeeney, Kansas, destroying 45 homes, killing five people, and injuring 100. The storm's path was less than a mile long.
- 1955 – A complex tornado family passed near Scottsbluff, Nebraska, including an F4 tornado that killed two people and injured 29. The event was extensively photographed and was the subject of one of the most detailed tornado studies of the time. An attempt to estimated the wind speed of the F4 storm from makings on the ground failed because it had multiple vortices, a phenomenon that was not known until the 1970s.

The 1999 Sydney hailstorm was the costliest natural disaster in Australian insurance history, causing extensive damage along the east coast of New South Wales. The storm developed south of Sydney on the afternoon of Wednesday, 14 April 1999, and struck the city's eastern suburbs, including the central business district, later that evening.
The storm dropped an estimated 500,000 tonnes of hailstones in its path. The insured damage bill caused by the storm was over A$1.7 billion (equivalent to $3.8 billion in 2022), with the total bill (including uninsured damage) estimated to be around $2.3 billion. It was the costliest single natural disaster in Australian history in insured damage, surpassing the $1.1 billion in insured damage caused by the 1989 Newcastle earthquake. Lightning also claimed one life during the storm, and the event caused approximately 50 injuries. (Full article...)Topics
