From May 10–12, 2014, a large and widespread tornado outbreak of 44 tornadoes spanned across portions of the central and Great Plains regions of the United States. The May 11 portion is sometimes referred to as the Mother's Day tornado outbreak by locals, due to it occurring on the celebration at the time. The outbreak began on the 10th, with isolated tornadoes across Idaho, Kansas, Missouri and also Alabama. The strongest tornado of that event was an EF2 tornado that struck Orrick, Missouri, causing widespread damage in town.
The following day on the 11th, dozens of tornadoes were reported across Kansas, Nebraska, Iowa and South Dakota, with the event's epicenter taking place across southern and eastern Nebraska, where a prolific and cyclical, high-precipitation supercell produced 17 tornadoes from areas southeast of Hastings, to the Omaha metropolitan area. Two large EF3 tornadoes caused severe damage to portions of Clay, Fillmore, York and Seward counties. The first one impacted rural farmsteads until eventually passing by Sutton. The parent supercell brought in powerful rear flank downdraft winds that were estimated at 100 mph (160 km/h) into the downtown area. The second EF3 was a massive and rainwrapped wedge tornado, which spanned 1.5 mi (2.4 km) wide and struck farms near Cordova, before eventually making a direct hit on the small city of Beaver Crossing. Severe rear flank downdraft and inflow winds occurred alongside as well as the supercell tracked through southeastern Nebraska. Winds of 70 mph (110 km/h) were reported near the Omaha metro area, notably Douglas County.
On the 12th, minor tornadic activity was reported. Only two tornadoes, both rated EF0 occurred outside of Elyria and Medina, Ohio, before the outbreak came to an end.
Alongside tornadic events, major and historic flash floods caused by an organized convective complex struck northern Ohio on May 12. A winter storm brought heavy snow cover for parts of the Rocky Mountains and High Plains. 43 in (110 cm) of snow was reported at the Sierra Madre Range, Wyoming. One person was killed along US 285 near Denver, Colorado by the storm.
Only one person was injured by one of the tornadoes from this outbreak. Other injuries were inflicted by the winter storm that persisted through May 10–12, where one death also occurred.
