On January 1, the Storm Prediction Center (SPC) began highlighting the potential for severe weather across portions of the central Gulf Coast and lower Mississippi Valley.

[12] On January 3, the combination of high dewpoints, marginal instability, and strong wind shear allowed for the development of supercells across central and southern Mississippi, where an Enhanced risk was briefly introduced.

Activity spread eastward on January 4, with a second EF2 tornado causing substantial damage north of Dozier, Alabama.Early on March 24, the SPC outlined an Enhanced risk for severe weather across portions of southwestern Missouri, northwestern Arkansas, and northeastern Oklahoma, where conditions were expected to become favorable for strong supercells.

[16] At 22:21 UTC, a waterspout spawned over Keystone Lake and moved through Sand Springs, Oklahoma, causing EF2 damage in a mobile home park where one fatality and 30 injuries were observed.

[24] The most significant event of the outbreak was a violent, long-tracked, very high-end EF4 wedge tornado that moved along a 30.14 mile-long path across several counties in northern Illinois, killing two people and injuring another 22.

Later that evening, a multiple-vortex EF1 tornado struck Lake City, Iowa, where homes were damaged, trees and power lines were downed, and the local high school had its roof torn off.

[41] Later that evening, a strong, rain-wrapped EF3 tornado partially debarked trees and swept away an unanchored house near Lovilia, Iowa, before weakening and striking the town of Albia at EF1 strength.

Numerous anchor-bolted frame homes in Coal City were damaged or destroyed, and a few were leveled or swept from their foundations, though vehicles parked at these residences were not moved, and nearby vegetation was not defoliated or debarked, precluding a higher rating.

The tornado moved out of Braidwood and maintained EF2 strength as it continued along its southeasterly path through rural areas, rolling a recreational vehicle, damaging the roof of a frame home, snapping numerous power poles, and completely destroying an outbuilding before dissipating.

On the afternoon of July 12, clusters of intense supercells formed over North Dakota and moved southeastward into Minnesota, producing large hail, damaging winds, and tornadoes.

[49][50] The supercells then merged into a long-lived, intense derecho that moved swiftly southeastward from Wisconsin and Illinois through the Ohio and Tennessee Valleys into the Southeastern United States on July 13, producing hundreds of wind damage reports over a 900 miles (1,400 km) stretch.

[51][52] Farther to the west, an isolated, southwestward supercell produced a slow-moving, but destructive high-end EF3 stovepipe tornado near Nickerson, Kansas, completely debarking trees and cleanly sweeping away an unanchored farm home.

[33][54] Later on July 14, another wave of intense severe weather affected mostly the Appalachian Mountains regions with numerous supercells, multi-cells, and bowing segments forming and moving generally southward, producing hundreds of damaging wind reports.

The first two tornadoes touched down in southern Texas during the early morning hours of the 30th, including an EF1 in Los Coyotes that was caught on surveillance video lifting a barn from its foundation and destroying it.

Trees were partially debarked and denuded, homes were heavily damaged, a well-built metal frame hog containment building was obliterated, and a heavy steel oil tank was thrown by this strong tornado.

[78] The outbreak also spawned the only known tornado to touch down in Michigan during the month of December, an EF1 that struck the Detroit suburb of Canton, causing considerable damage to vehicles, an industrial park, and a gas station.

A large, destructive high-end EF3 tornado touched down south of Clarksdale, Mississippi, killing two people and severely damaging or destroying about 15 homes in that area.

[78] Another destructive EF3 tornado struck the small community of Lutts, Tennessee, after dark, destroying homes and a church, and completely flattening the local post office.

A strong F2 tornado passed through the west edge of Groß Laasch, flattening a large swath of trees and severely damaging a brick train station, which sustained roof loss and collapse of multiple exterior walls.

Numerous large and well-built brick homes, churches, and other buildings were heavily damaged, several had their roofs torn off, and a few sustained collapse of exterior walls.

The first tornado of the event, which was rated F2, occurred in eastern France, tearing the roofs off of homes, destroying barns, damaging vehicles, and downing trees and power lines in the Gerbépal area.

Multiple well-built homes and apartment buildings along the path had their roofs torn off, a few sustained loss of exterior walls, and debris was scattered throughout residential areas.

[102][103][104]On the evening of July 8, a large and violent cone-shaped IF4 tornado impacted areas in and around the towns of Dolo and Mira, causing major structural damage within the Riviera del Brenta region of Italy, famous for its villas and channels.

Many buildings were badly damaged or destroyed,[105] and among them was the large, two-story, masonry construction Villa Fini restaurant and hotel from the 17th century, which was almost entirely leveled to the ground in Mira.

Another tornado of unknown strength caused roof damage, destroyed two garden sheds, and overturned a tractor near Bissen before striking Colmar-Berg, downing trees and injuring one person.

A long-tracked, rain-wrapped F3 wedge tornado spawned by a supercell thunderstorm struck the city of Xanxerê, Santa Catarina in Brazil during the afternoon of April 20, resulting in major damage.

Around 5 p.m. local time, a tornado touched down near Dubbo, in the Central West region of New South Wales and in its 200 meter wide path through a semi-rural area damaged homes, sheds, and vegetation.

[139] In Treze Tílias, an F0 tornado downed several trees and destroyed 10 roofs; a hospital was flooded and the electricity service was disrupted at 7:00 pm local time (UTC−02:00).

[141][142] Numerous houses were partially destroyed, a major shopping center and desalination plant were also damaged, whilst many trees were snapped and boats and trucks were reportedly flipped.

[141] Tennis ball sized hail and flash flooding with rainfall up to 144 mm (5.7 in) in an hour was also recorded from the same storm system, with damage reported across the Greater Sydney Area and the Illawarra.
