This page documents the tornadoes and tornado outbreaks of 1998, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes, however by the 1990s tornado statistics were coming closer to the numbers we see today.
Synopsis
The 1998 tornado season saw record numbers of tornadoes and also the most fatalities since 1974. A number of tornado events resulted in large loss of life. In February, a series of tornadoes caused 42 fatalities in Florida. In March, a tornado killed 12 in Georgia. In April an F5 tornado killed 32 in the Birmingham, Alabama area. By year's end, 130 people had been killed in the United States.

February 15–17
February 22–23

An F2 tornado touched down at approximately 5:25 AM in the town of Mattoon, Illinois. Winds reached around 152 miles per hour and damaged over 90 homes damaged and eight homes and six businesses were destroyed. Tornado Warnings were in effect but had expired at 5:00 AM leaving no warning from tornado sirens or trained spotters in the field.

An unseasonably-strong tornado outbreak affected the Upper Midwest on March 29. 16 tornadoes struck across the region—14 in Minnesota and two in Wisconsin. 13 of the tornadoes in Minnesota were spawned by a single supercell thunderstorm. Two people were killed, and 21 others were injured. Most of the damage was caused by three tornadoes: an F4 tornado that hit the town of Comfrey, Minnesota, an F3 tornado that struck St. Peter, Minnesota, and an F2 tornado that hit Le Center, Minnesota.

April 6–9
An extremely violent F5 tornado started North of Kellerman, Alabama and traveled through Northern Jefferson County, before dissipating in Northern Pratt City. The F5 tornado produced catastrophic damage in Oak Grove, McDonald Chapel, and the small community of Edgewater. The same supercell that spawned the Birmingham F5 spawned an F2 that continued into neighboring St. Clair County, killing two people. A high-end F2 tornado struck Dunwoody, Georgia, a northern suburb of metro Atlanta late on April 8, striking parts of Dekalb and Gwinnett Counties. It is one of the strongest and most damaging tornadoes ever recorded to have hit the area. In all, 62 tornadoes touched down from the Midwestern United States and Texas to the Mid-Atlantic. The outbreak was responsible for at least 41 deaths, with seven in Georgia and 34 in Alabama.
April 15–16
A two-day tornado outbreak affected portions of the Midwestern United States, Mississippi and Tennessee Valleys on April 15–16, with the worst of the outbreak taking place on the second day. On that day, at least 10 tornadoes swept through Middle Tennessee—three of them touching down in Nashville, causing significant damage to the downtown and East Nashville areas. Nashville became the first major city in nearly 20 years to have an F2 or larger tornado make a direct hit in the downtown area. In addition, the outbreak produced several other destructive tornadoes in Middle Tennessee. One of them, southwest of Nashville, was an F5 tornado—one of only two ever recorded in the state. That tornado remained mainly in rural areas of Wayne and Lawrence Counties. Other tornadoes during the 2-day outbreak struck Arkansas, Alabama, Illinois and Kentucky. 12 people were killed by tornadoes during the outbreak, including two in Arkansas, three in Kentucky, and seven in Tennessee.
May
There were 310 tornadoes confirmed in the U.S. in May.
A large squall line with embedded supercells crossed much of Minnesota, producing large hail, destructive downburst winds, and five weak, but damaging F1 tornadoes, which killed one and injured 31. In all, the storms caused $1.5 billion in damage.
May 30–31
A historic tornado outbreak and derecho began on the afternoon of May 30 and lasted into the next day. It affected a large portion of the northern half of the United States and Southern Ontario from Southeastern Montana east-southeastward to the Atlantic Ocean. The initial tornado outbreak, including the devastating Spencer tornado, hit Southeast South Dakota on the evening of the May 30. The Spencer tornado was the most destructive and second deadliest tornado in South Dakota history. 13 people were killed; seven by tornadoes and six by the derecho, and damage was estimated to be at least $500 million. Over two million people lost electrical power, some for up to 10 days.

For portions of New York, New Jersey and Pennsylvania, it was the second historic severe weather outbreak in three days, as it immediately followed the Late-May 1998 tornado outbreak and derecho on May 30–31, which spawned 41 tornadoes over New York, New Jersey, Pennsylvania and Vermont, caused an estimated $83 million in damage, 109 injuries and one fatality.
A very large F2 tornado occurred in the open countryside near Columbus, Nebraska, slowly churning through fields and destroying a few farmsteads.
June 29

The tornado then tracked northeast, causing damage to an abandoned house and destroying a barn and garage. Entering Alfalfa County, the tornado then destroyed an office building and a gas plant and blew the roof off a nearby modular home. Multiple witnesses reported this multiple-vortex tornado to have been at least a quarter of a mile wide. The second tornado, rated F0, touched down southeast of Cherokee in Alfalfa County where it was spotted by a county sheriff's deputy.
