Preceded by more than a week of heavy rain, a slow-moving storm system dropped tremendous precipitation across much of Texas and Oklahoma during the nights of May 24–26, 2015, triggering record-breaking floods. Additionally, many areas reported tornado activity and lightning. Particularly hard hit were areas along the Blanco River in Hays County, Texas, where entire blocks of homes were leveled. On the morning of May 26, the National Weather Service issued a flash flood emergency for southwest Harris County (which includes the city of Houston) and northeast Fort Bend County. The system also produced deadly tornadoes in parts of Mexico, Texas, and Oklahoma.
According to Bob Henson from Wunderground, inflow of low-level moisture from the Gulf of Mexico and the combination of very slow moving large-scale storm systems set the stage for the floods. He added,"Upper-level winds were largely aligned with the low-level frontal zone, an ideal setup for “thunderstorm training” (successive downpours over the same area). In addition, rains were concentrated by several mesoscale convective vortices, small-scale centers of low-pressure that developed along the frontal bands, in some cases resembling mini-tropical cyclones."The stationary trough during May is linked to both the El Niño and amplified midlatitude short-wave train.
On May 14, 2015, prior to extensive flooding beginning around May 24, flash flood warnings were issued for counties in South East Texas. At least 31 people were killed, including 27 in Texas and 4 in Oklahoma, and another 11 remain missing.
Flooding along the Wichita River prompted evacuations of 390 homes in Wichita Falls. Projections from the National Weather Service indicated that the river would reach a record crest of 25.5 ft (7.8 m) on May 26. Up to 100,000 customers were without power.
Wichita Falls and Corpus Christi broke their previous records for all-time wettest month. Many parts in northern Texas recorded over 20 in (510 mm) of rain.
A 25-foot-by-25-foot sinkhole near a runway at the Dallas/Fort Worth International Airport caused the closure of the runway for a few hours.
Also on May 25, historic flooding along Shoal Creek inundated House Park in Austin, Texas damaging the turf among other things and forcing the Austin Aztex to search for a temporary home.
More than 500 water rescues were carried out by firefighters, which involved for the most part stranded motorists. At least 2,500 vehicles were abandoned, when drivers had to seek higher grounds.
During the overnight of May 25–26, nearly 11 in (280 mm) of rain fell near Houston, setting off further flash floods. Two people drowned after being trapped in their cars while a third was later found in bayou. A fourth person lost their life when an evacuation boat capsized during the morning of May 26. On May 26, Houston Mayor Annise Parker, estimated up to 4,000 properties with significant damage.
During the overnight of May 24–25, more than 12 in (300 mm) fell along the watershed of the Blanco River. In just a few short hours, the river rose from roughly 5 ft (1.5 m) to a crest just over 41 ft (12 m), well over the 13 ft (4.0 m) flood-stage, near Wimberley. This broke the river's all-time peak of 32 ft (9.8 m) set in 1929. Tremendous flash flooding ensued as a result, with areas of Hays County being particularly hard hit.
Entire blocks of homes in Wimberley were swept away by a "tidal wave of water" residences destroyed in the town alone. For the first time, the river covered portions of Interstate 35, shutting down traffic for hours. Large trees and debris were deposited across the roadway.with officials reporting 350–400
One person in San Marcos, Texas was confirmed dead. people have been left homeless along the river.Thirteen people were carried away when the home they were in was swept downstream. Residents reported seeing it being destroyed after striking a bridge. One occupant was recovered with significant injuries while the other twelve remain missing. At least 1,200
On May 23, flash flooding along Highway 20 near Claremore claimed the life of a firefighter attempting to rescue people in an apartment complex. He was pulled into a storm drain obscured by the rising waters and carried hundreds of yards away. A fellow firefighter attempting to save him was pulled in as well but managed to escape. The day also saw some roads submerged in as much as 9 inches (230 mm) of water, and thousands of OG&E customers experienced power outages as a result of the flooding in Oklahoma City and Del City.
A station Oklahoma City recorded 19.48 inches (495 mm) of rainfall in May 2015, which made it the all-time wettest month on record. Records date back to 1890.
From May 1 to May 25, 122 tornado warnings were reported by the National Weather Service in Oklahoma, more than in the same period
The Oklahoma Department of Transportation reported on May 26 that a number of highways were closed because of high water or damage from previous flooding.
Flooding in Ruston, Louisiana on 18 May caused an eleven-year-old boy to drown in a submerged car along Colvin Creek.
On May 24, voluntary evacuations were extended to include 2,177 homes near the Wichita River. On May 25, near Houston, about 400 homes were placed under mandatory evacuation orders downstream from the Louis Creek Dam.
On May 25, Texas Governor Greg Abbott declared a state of emergency for 24 counties as a result of the ongoing disaster, and called the floods the biggest in Texas history. On May 26, President Barack Obama announced federal resources to help affected areas in Texas, and signed a disaster declaration for Oklahoma. Houston Mayor Annise Parker declared a local state of disaster for the city of Houston on May 26.
On May 26, Governor Mary Fallin declared a state of emergency for all 77 counties in Oklahoma.
A study by Utah State Universityanalyzed the pathway in which anthropogenic global warming contributed to the persistent precipitation in May 2015: Warming in the tropical Pacific acted to strengthen the teleconnection toward North America, modification of zonal wave-5 circulation that deepened the stationary trough west of Texas, and enhanced Great Plains low-level southerlies increasing moisture supply from the Gulf of Mexico. Attribution analysis indicated a significant increase in the El Niño-induced precipitation anomalies over Texas and Oklahoma when increases in the anthropogenic greenhouse gases were taken into account.
Studies by the Scripps Institution of Oceanography found for Texas that precipitation totals have increased 10 percent in the last century, but mostly in eastern Texas, with more frequent, severe and longer drought conditions in west Texas.
The report Regional Climate Trends and Scenarios for the U.S. National Climate Assessment (NCA) from 2013 by NOAA, projects that parts of Texas, and parts of the Great Plains region can expect up to 30% (High emissions scenario based on CMIP3 and NARCCAP models) increase in extreme precipitation days by midcentury. This definition is based on days receiving more than one inch of rainfall.
A study from April 2015 concluded that about 18% of the moderate daily precipitation extremes over land are attributable to observed temperature increase since the Industrial Revolution and that this primarily results from human influence.

This page documents notable tornadoes and tornado outbreaks worldwide in 2015. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, Brazil and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather including strong thunderstorms, winds and hail.
The tornado outbreak sequence of May 5–10, 2015 was a six-day outbreak of tornado activity that affected the Great Plains of the United States in early May 2015. On May 6, strong tornadoes impacted the Oklahoma City area, along with rural parts of Kansas, Texas, Arkansas, South Dakota, and Nebraska. The outbreak coincided with major flooding, with large amounts of rain falling in parts of Nebraska, Kansas, Oklahoma, and Texas. The National Weather Service forecast office in Norman, Oklahoma issued a "flash flood emergency" for Oklahoma City following record-breaking rainfall that occurred in the area that evening. The outbreak sequence resulted in five tornado-related deaths, along with two flood-related deaths. A total of 127 tornadoes were confirmed and rated as a result of this outbreak sequence.
The Tornado outbreak of November 16–18, 2015 was a highly unusual nocturnal late-season tornado outbreak that significantly impacted the lower Great Plains on November 16 before producing additional weaker tornadoes across parts of the Southern United States the following two days. The first day of the outbreak spawned multiple strong, long-track tornadoes, including two consecutive EF3s that caused major damage near Pampa, Texas. Overall, the outbreak produced 61 tornadoes in all, and was described as by the National Weather Service office in Dodge City, Kansas as being "unprecedented in recorded history for southwest Kansas." Despite spawning multiple strong tornadoes after dark, no fatalities and only one minor injury occurred as a result of the outbreak.
The December 2015 North American storm complex was a major storm complex that produced a tornado outbreak, a winter storm, a blizzard and an ice storm in areas ranging from the Southwestern United States to New England. Tornadoes impacted areas around Dallas, Texas. Several states, especially Missouri, were affected by heavy rain and snow causing severe floods. As the system moved through the Great Lakes region, heavy rain, ice pellets and heavy snow fell in the entire region. Wintry mix moved through southern Ontario and Quebec had significant snowfall on December 29. Almost 60 people were killed in the storm system and its aftermath, which made it one of the deadliest of such systems of 2015 in the United States.
The tornado outbreak of April 8–9, 2015 was a relatively small but damaging outbreak of tornadoes that occurred in parts of the Great Plains and in the Midwestern United States. 27 tornadoes were confirmed during the two days, most of them weak, however a select few of them were powerful and damaging.
The tornado outbreak of November 30 – December 2, 2018 was a late-season tornado outbreak that occurred across portions of the West South Central states and Midwestern United States. As a potent shortwave trough moved across the southern portions of the country, it was met with ample moisture return and destabilization, resulting in widespread severe thunderstorms that produced damaging winds, hail, and tornadoes. The event began late on November 30 in Oklahoma, spreading east and resulting in one fatality in Aurora, Missouri. Several tornadic supercells moved across portions of Illinois on December 1, and resulted in 29 confirmed tornadoes. This outbreak was the largest December tornado event on record in Illinois history, surpassing the December 1957 tornado outbreak sequence. The most significant tornado of the event was an EF3 that impacted Taylorville, Illinois, damaging or destroying hundreds of structures and injuring 22 people.
This page documents notable tornadoes and tornado outbreaks worldwide in 2019. Strong and destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh, and Eastern India, but can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, Argentina, and Australia. Tornadic events are often accompanied by other forms of severe weather, including strong thunderstorms, strong winds, and hail.
The tornado outbreak of April 17–19, 2019 was a multi-day, widespread severe weather event stretching from the South Central United States to the East Coast of the United States. On the heels of a significant tornado outbreak just a few days prior, another potent upper-level trough progressed eastward and served as the impetus for widespread, damaging thunderstorms. The outbreak began on April 17 with several short-lived, generally weak tornadoes across Kansas, Oklahoma, and Texas. The following day, a total of 44 tornadoes were recorded across central Mississippi, tying the Hurricane Rita tornado outbreak as the largest in Mississippi state history. On April 19, the event spread eastward. North Carolina recorded 12 tornadoes, the state's sixth largest outbreak in a single day, while Virginia recorded 16 tornadoes, its third-most in a 24-hour period. Overall, 96 tornadoes were confirmed, the strongest of which was a high-end EF3 that heavily damaged homes and outbuildings north of Oak Level, Virginia. There were no fatalities recorded in association with tornadic activity, but four people were killed by fallen trees in strong straight-line winds.
The tornado outbreak sequence of May 2019 was a prolonged series of destructive tornadoes and tornado outbreaks affecting the United States over the course of nearly two weeks, producing at least 391 tornadoes, including 51 significant events (EF2+). Eighteen of these were EF3 tornadoes, spanning over multiple states, including Nebraska, Kansas, Texas, Missouri, Oklahoma, Indiana, Iowa, and Ohio, with additional tornadoes confirmed across a region extending from California to New Jersey. Two EF4 tornadoes occurred, one in Dayton, Ohio, and the other in Linwood, Kansas. Four tornadoes during this outbreak were fatal, causing a total of eight fatalities. The deadliest of these occurred on May 22 near Golden City, Missouri, where an EF3 tornado took three lives, including an elderly couple in their eighties.
The tornado outbreak of January 10–11, 2020 was a two-day severe weather event stretching from the South-Central Plains eastward into the Southeast United States. An eastward-moving shortwave trough tracked across the continental United States through that two-day period, combining with abundant moisture, instability, and wind shear to promote the formation of a long-lived squall line. Hundreds of damaging wind reports were received, and 79 tornadoes occurred within this line, making it the third largest January tornado outbreak on record. Three tornadoes—an EF1 in eastern Texas, an EF2 in northern Louisiana, and an EF2 in western Alabama—led to a total of seven deaths, all in mobile homes. Extensive damage and several other injuries occurred as well. The severe weather event was notable in that it was forecast well in advance, with the Storm Prediction Center first highlighting the risk area a full week beforehand.
“The bottom line is that things are not that complicated,” Dr. Knutti said. “You make the world a degree or two warmer, and there will be more hot days. There will be more moisture in the atmosphere, so that must come down somewhere.”
We show that at the present-day warming of 0.85 °C about 18% of the moderate daily precipitation extremes over land are attributable to the observed temperature increase since pre-industrial times, which in turn primarily results from human influence. … Likewise, today about 75% of the moderate daily hot extremes over land are attributable to warming.
