The April 15-16, 1998 tornado outbreak was a two-day tornado outbreak that affected portions of the Midwestern United States, Mississippi and Tennessee Valleys on April 15 and April 16, 1998, with the worst of the outbreak taking place on the second day. On that day, 13 tornadoes swept through Middle Tennessee—two 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 (the only official one) ever recorded in the state (the other, unofficial however, being in Pinson, Tennessee in 1923). 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: two in Arkansas, three in Kentucky, and seven in Tennessee (one in Nashville, three in Wayne County, and three more elsewhere).
This tornado outbreak occurred at the end of the record-setting 1997-1998 El Niño event.

One week after the Birmingham tornado outbreak took place across Alabama and Georgia on April 8-9, 1998 and several other states on April 7, a similar pattern developed across the Midwest and southeastern United States starting on April 16, 1998. A very strong low pressure system developed across the central part of North America and was associated with a long cold front. Ahead of the storm, the warm moist air generated from the Gulf of Mexico increased the likelihood for a significant weather event. On April 15, activity developed across the Mid-Mississippi Valley and southern Ohio Valley where several tornadoes touched down in Illinois starting in the late afternoon before moving into Arkansas during the overnight hours where the first fatalities were reported.
On April 16, as the main low-pressure system was near the Great Lakes and its cold front crossing the Mississippi River, dew points reached the mid to upper 60s across the Tennessee Valley while later in the day, CAPE values reached 1600 J/kg while dry air intrusion was also on the rise increasing the threat of severe weather across the area. As the bulk of the supercells moved out of Arkansas, the tornadic activity was slower during the morning hours before re-intensifying west of Nashville early in the afternoon. Major tornadoes struck from southern Tennessee to southern Kentucky with additional storms as far north as Michigan and several other storms in Alabama across Walker and Cullman Counties, which was slightly north of the areas that were hardest hit by the previous outbreak.
This tornado, rated F3, touched down near the intersection of Charlotte Pike and Forty-Sixth Avenue and traveled directly through downtown Nashville. The tornado manifested itself as a large area of rapidly rotating rain curtains and dark clouds, rather than a traditional funnel. After crossing the Cumberland River, it passed through East Nashville, Donelson, and Hermitage before finally lifting northwest of Lebanon in extreme northern Wilson County. An ROTC student from Vanderbilt University was trapped under a fallen tree in Centennial Park and later died from his injuries. The tornado blew many windows out of office buildings. Many large buildings, including skyscrapers, were damaged. The TPAC building had over 100 windows blown out. 30 small airplanes were damaged at Cornelia Fort Airport. 35 total buildings in downtown Nashville were deemed structurally unsound after the tornado. The tornado blew down 3 construction cranes on the construction site of the Tennessee Oilers' football stadium near the Cumberland River, before crossing the river. Many signs were downed throughout downtown as well.
The tornado continued east and hit the residential section of East Nashville. At least 300 homes were damaged in East Nashville, many of which lost a good part of their roofs, with a few destroyed. Trees were uprooted and telephone poles were knocked down in this area. A nursing home was hit and all the residents had to be evacuated. A church, which was well over 100 years old, received major damage. It then re-crossed the Cumberland River, where more trees were downed and more homes and other buildings were damaged across Donelson and Hermitage. Over a thousand trees were blown down at Andrew Jackson's home, The Hermitage. Some of those trees were well over 200 years old, with a few having been planted by Andrew Jackson himself.
The tornado moved into Wilson County, downing many trees, power lines, and signs. Several homes suffered mostly roof damage in the area. A baseball field and a lumber yard were damaged in Mt. Juliet. Part of the roof was taken off a bank in Mt. Juliet as well. The tornado then continued across rural Wilson County and produced sporadic damage before it dissipated just south of the Cumberland River in extreme northern Wilson County.
No fatalities were reported with this F5 wedge tornado as it touched down just inside Wayne County and traveled through sparsely populated areas of Lawrence County, west and northwest of Lawrenceburg. There were 21 injuries, however. It did not significantly affect any towns along its 19.3 miles (31.1 km) path. However, many large and well-built homes with anchor bolts were completely leveled with some swept clean from their foundations, and vehicles were thrown hundreds of yards. One truck was rumored to have been taken about 20 miles (32 km), though this was never confirmed. A 200-foot section of grass was scoured away at a pasture, leaving only bare soil behind. Clumps of dirt were pulled up as well. Many trees and power lines were downed as well as 75 utility poles. Some of the trees were completely debarked, and several livestock were killed as well.
South Central Kentucky also received severe weather from this outbreak. The most notable of the storms that occurred in South Central Kentucky that day was a particularly strong supercell storm that dumped baseball-sized hail on central Warren County including the Bowling Green central business district and Western Kentucky University causing massive amounts of damage to cars as well as structures. The storm also caused flash flooding in the area of WKU's main campus. The damage from the hail was so great that it seemed to overshadow the F3 tornado event happening in the southern part of the county, which was more rural. The tornado then moved into Barren County actually crossing a bend in the northern portion of Barren River Lake near the small town of Lucas. The tornado then would pass just south of downtown Glasgow and cross the Cumberland Parkway just west of the Barren/Metcalfe county line. It would then dissipate right at that county line. An F2 was later spawned by this supercell in Metcalfe County, crossing the Cumberland Parkway in the western part of the county and passing just to the south of the county seat, Edmonton.
