On November 16, an unusual late-season nocturnal tornado outbreak produced numerous tornadoes in parts of Texas, Oklahoma, Kansas, and Nebraska during the late evening and overnight hours.
A long-track EF3 wedge tornado began northeast of Liberal, Kansas, and moved along a 51-mile-long (82 km) path through several counties before dissipating near Montezuma, causing extensive damage to farmsteads and trees along the path.
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.
Another large EF2 wedge tornado spawned by the same supercell caused considerable damage in rural areas between the towns of Ensign and Cimarron as well.
A separate supercell storm also produced an EF2 tornado that caused damage to farms near Ness City as well.
The towns of Grainfield and Lenora sustained direct hits from EF1 tornadoes, resulting in moderate damage at both locations.
Further to the south, a large EF3 wedge tornado passed to the southeast of Pampa, Texas, before dissipating near Miami, debarking trees, toppling metal high-tension truss towers, and causing some ground scouring as it passed through rural areas.
A well-anchored mobile home was completely swept away with little debris recovered, and nearby heavy farm equipment along with a two-ton truck were thrown 150 yards away.

Shortly after the initial Pampa tornado, a second large EF3 passed to the southeast of the city, missing densely populated areas by just three miles.
This large cone tornado leveled a large chemical plant complex on the outskirts of town, tossed vehicles, and destroyed a manufactured home.
The destruction of the chemical plant complex resulted in a major gas leak and chemical spill, prompting a Hazmat team to respond.
A large EF2 tornado passed near Groom, heavily damaging a frame home, destroying a well-built metal frame outbuilding, and moving a flat-bed truck 50 yards, while another EF2 heavily damaged a well service rig near Seminole.
As the supercells crossed into the Oklahoma panhandle later that night, additional tornadoes touched down, including an EF2 that caused damage near the town of Fort Supply.
Many other tornadoes were sighted in rural areas across the four states that night as well, though they remained mostly over open country and caused minimal damage.
Due to the highly anomalous time of year and geographical locations of the outbreak, the National Weather Service office in Dodge City, Kansas described the event as being "unprecedented in recorded history for southwest Kansas".
The parent storm system went on to produce additional weak tornadoes across the southern United States on the 17th and 18th, some of which impacted suburbs of Dallas and Atlanta.
Overall, the outbreak produced 61 tornadoes, though no fatalities occurred.
