The tornado outbreak sequence of May 17–25, 2019 is an ongoing major tornado outbreak sequence affecting the Southern Plains and central areas of the United States, which has so far produced multiple tornadoes, including 29 significant events (EF2+).

Meteorological synopsis

May 17

The threat for organized severe weather on May 17 was first outlined five days prior, when the Storm Prediction Center (SPC) outlined the Texas and Oklahoma panhandles, as well as western Kansas, in a 15% probability contour.[1] On the morning of May 14, this risk area was expanded and 30% severe probabilities were introduced as the SPC gained confidence in a widespread and prolonged severe weather outbreak.[2] For the first time in the organization's history, a threat of severe weather was introduced for their entire day 4–8 period.[3] By May 17, a dual Enhanced risk existed across the Central Plains, one across much of Nebraska and the second across southwestern Texas. As a large scale upper-level trough ejected into the region, dew points in the low to mid-60s °F surged north in front of a dryline. A cap across the region allowed the atmosphere to become extremely unstable, while an eastward-moving dryline was expected to become the focus for severe thunderstorms later in the day. The SPC noted uncertainty regarding convective development farther south across southwestern Kansas into Oklahoma but mentioned that any thunderstorms would be capable of significant severe weather if they came to fruition.[4]

By late afternoon, several discrete supercell thunderstorms formed across northwestern Kansas and progressed into western and central Nebraska. While weak low-level winds and the continuing presence of a cap caused several splitting storms that destructively interfered with one another,[5] one supercell later in the evening formed within a strongly sheared environment, becoming intense and long-lived as it progressed northeastward.[6] It produced seven tornadoes in total, five of which were weak. One EF2 tornado northeast of Stockville rolled 1,400 lb (640 kg) hay bales and snapped twelve power poles. The strongest was a high-end EF3 that extensively damaged or destroyed structures at a farmstead.[7] Later in the evening, a long-lived supercell formed in southwestern Kansas where SPC had previously highlighted uncertainty in convective development. This supercell produced four tornadoes in areas southeast of Dodge City, including an EF3 and two EF2s.[8]

May 20

On the morning of May 20, 2019, the Storm Prediction Center in Norman, Oklahoma issued a high risk for severe weather across western and central Oklahoma and northwest Texas.[9] As a precaution, many public school districts, private schools and colleges (including the University of Oklahoma) throughout Oklahoma announced during the afternoon and evening of May 19 that they would cancel all classes and extracurricular activities for the following day, if not hold classes during the morning only. Ironically, in response to the deaths of seven students at Plaza Towers Elementary School in Moore after the May 20, 2013 tornado hit that school and nearby Briarwood Elementary, several of the public primary and secondary schools that cancelled classes had since installed underground storm shelters for student and faculty use in the event that a tornado approached during school hours. The El Reno, Oklahoma school district – which has storm shelters at seven of its schools (six underground and one above-ground shelter – was one of the few in sections of central and western Oklahoma under highest threat of significant severe weather that decided to hold regular classes that day; El Reno Superintendent Craig McVay defended the decision on safety grounds, acknowledging that between 75% and 90% of students in the district do not have shelters in their home. Businesses, churches and other venues also decided to cancel events and activities, while some city government offices (including in Oklahoma City) and Tinker Air Force Base instituted liberal leave policies to allow employees to arrive home prior to the onset of severe thunderstorm activity.[10][11] By midday, the SPC increased the risk of significant tornadoes in northern portions of the Texas Panhandle, southwestern and central Oklahoma (including Oklahoma City) from 30% to 45%.[12]

The Storm Prediction Center issued a Particularly Dangerous Situation Tornado Watch (the 197th severe weather watch issued in 2019) at 1:35 p.m. CDT for portions of the eastern Texas Panhandle and the Texas High Plains. A second PDS Tornado Watch (watch #199) was issued at 2:45 p.m. CDT for much of Oklahoma and western portions of north Texas, indicating >95% probabilities for all severe hazards (including probabilities of at least two tornadoes and one or more strong tornadoes [rated EF2 or higher], ten or more cases of straight-line thunderstorm winds of at least 58 miles per hour [93 km/h] and at least one case of 75 miles per hour [121 km/h] winds, and ten or more cases of hail of at least one inch [2.5 cm] in diameter and at least one case of hail larger than two inches [5.1 cm] in diameter); this was the second PDS watch with such high probabilities of significant severe weather to be issued by the SPC, after one issued for much of Alabama and portions of southeast Mississippi, southern middle Tennessee and northwest Georgia during the historic Super Outbreak of April 27, 2011.[13]

An EF-2[14] wedge tornado passed just north of Mangum, Oklahoma, damaging several homes and completely sweeping one home off its foundation. Moderate ground scouring occurred near Mangum with this tornado. Rare and highly visible twin tornadoes caused light damage in Canadian County, Oklahoma and Kingfisher, Oklahoma counties Northeast of El Reno, Oklahoma and Southwest of Piedmont, Oklahoma in Central Oklahoma. They were captured live on air by KFOR-TV's Chopper 4 Helicopter.[15] Several other tornadoes were reported across Texas, as well as damage from a reported tornado in Missouri. After dark, an embedded supercell produced a mile-wide EF2 tornado east of Tulsa, Oklahoma. Radar confirmation along with a nearly 3-mile-wide debris ball as well as a very intense velocity signature from this tornado prompted the National Weather Service office in Tulsa to issue a rare tornado emergency at 10:49 p.m. CDT for portions of Cherokee and Delaware counties; the storm directly impacted Leach, Oklahoma and adjacent communities. A subsequent squall line that moved through the southern half of Oklahoma during the early morning hours of May 21 produced three tornadoes in Cleveland and Pottawatomie counties, including two EF1s in Norman and Noble, which caused mostly tree damage, and an EF2 in Dale. Damage surveys are still ongoing, but 35 tornadoes were reported on May 20.[16]

May 21

The following day, a large and likely intense tornado developed from an embedded supercell west of the St. Louis, Missouri metro area, near Augusta, Missouri. Damage was reported, but the extent of it is unknown. Despite a tornado warning being issued for the St. Louis metro area, the city escaped any major damage. Several tornadoes were also reported in Kansas and Nebraska.[17] An EF-1 tornado tracked over Tulsa International Airport, injuring a man. The Airport was left unscathed; meanwhile, damage was reported across town. 37 tornadoes were reported on May 21. This day, severe weather resulted in a fatal car crash, which killed two people, as well as the drowning of another driver in Perkins, Oklahoma.

May 22

On May 22, the Storm Prediction Center issued a moderate risk for severe weather for Oklahoma, Kansas and Missouri. The potential for powerful tornadoes would linger from Tulsa, Oklahoma to Columbia, Missouri.

An early-morning EF-2 tornado struck Adair, Iowa with 1 fatality and 1 injury reported in addition to damage of 3 buildings and destruction of another on a farm.[18]

By 4:30 PM CDT, three Tornado Watches, stretching from north-central Texas to northwest and west-central Illinois were in effect, with two of them classified as PDS watches.[1]

A Tornado Emergency was issued at 8:19 PM CDT for a large and destructive tornado near Oronogo, MO. 4 tornadoes occured with this dangerous supercell, 3 of them being rated at EF3 strength. One EF3 near Golden City, MO killed 3 people.[19]

A large and violent tornado prompted a tornado emergency to be issued at 11:44 PM CDT by the National Weather Service for Jefferson City, Missouri. [20] Surveys found that this was a high-end EF3 that was on the ground for 19 miles and was almost a mile wide at its peak intensity, but did not cause any deaths.

May 23

At 8:11 AM CDT on Thursday, May 23, 2019, The National Weather Service in Lincoln issued a Tornado Warning for Lawrence County and Eastern Richland County in southeastern Illinois. [21] [22] [23] [24] A wedge tornado passed North of Canadian, Texas, completely leveling 2 homes.

May 24

On the morning of May 24, the Storm Prediction Center issued a slight risk of convective activity stretching from southwest Texas to the lower peninsula of Michigan, with a 5% risk of tornadoes for northern Illinois, far southern Wisconsin, and far eastern Iowa.[25] By the afternoon, this was upgraded to an enhanced risk for a portion of northwest Texas, with a 5% risk of tornadoes from there to Illinois.[26] Two EF1 tornadoes had already touched down in Kansas in the early morning hours, and in the afternoon tornado activity began again for the 8th day in a row. Just after 12:30 local time, two EF1 tornadoes touched down near Industry, Illinois, destroying outbuildings. [27] An EF1 tornado in Iowa City, Iowa destroyed outbuildings and large trailers,[28] and a series of EF0 tornadoes touched down in Missouri and Wisconsin.
